his

conviction by jury trial and life sentence for the death of an

His appeal raises a

Background

A. Facts
The overarching series of events giving rise to this
appeal are not in dispute.

Contested issues pertinent to Casey's

arguments on appeal, and the appropriate standard of review for
each, are addressed in the Discussion sections below.

While the

record is brimming with numerous additional details, we keep our
synopsis relevant to the questions we have been asked to consider.
In 2005, Puerto Rico Police Department ("PRPD") Agent
Jesús Lizardi-Espada ("Lizardi") was assigned to investigate Casey
undercover.

He eventually arranged with Casey's assistance to

purchase four pounds of marijuana on the island of Culebra in the
morning hours of August 1, 2005, from the drug supplier Alexander
Hernández.

Lizardi and Casey were to drive to Fajardo, from where

they would take a ferry to Culebra to meet Hernández.

A law

enforcement team led by Lizardi's supervisor, Agent José AgostoRivera ("Agent Agosto"), traveled to Culebra by plane to await
Lizardi and Casey's arrival.

When Agent Agosto did not see Lizardi and Casey arrive
on the ferry as planned, a search for Lizardi commenced. Later
that day, Agent Agosto found Casey at his workplace, a Holiday Inn
in Isla Verde, and spotted Lizardi's gray Ford truck in the hotel
parking lot.

Upon leaving the Holiday Inn in Lizardi's truck,

Casey was arrested and taken to PRPD general headquarters, where
he was read his rights, signed a Miranda waiver, and began being
questioned.

Casey, who remained in PRPD custody until midday the

following day, was moved to a PRPD precinct in Canóvanas and later
to one in Luquillo.

At some point, Casey told officers he was no

longer interested in talking with the police.
While Casey was in PRPD custody, Casey's grandparents
Mr. and Mrs. Rivera, with whom he lived, permitted law enforcement
officers to search his bedroom without a warrant.

In it, the FBI

discovered a loaded firearm inside a jacket pocket, Lizardi's cell
phone,

subsequently transferred from PRPD to FBI custody in Ceiba, where
he was confronted with this evidence, and in the course of further
questioning, requested an attorney.

It was there that his common-

law wife, Crystal Peña ("Peña"), came to visit him.

Statements

Casey made to her during their exchange were overheard by law
enforcement, and later admitted as evidence against him.
Further investigation revealed that on the morning of
August 1, 2005, Luis Algarín ("Algarín"), a cashier working at the

marina parking lot in Fajardo from which ferries to Culebra depart,
witnessed a person he later identified in a photo array as Casey
drive up to his booth in a gray truck, request to leave after
losing his parking lot ticket, and pay with a twenty-dollar bill.
Another parking lot employee, Peter Ávila-Natal, also observed on
that same day in the lot a pick-up truck missing a driver's side
window, and glass dust on the truck driver's elbow.

The FBI

recovered from the Fajardo parking lot a car window with what
appeared to be a bullet hole in the middle, and a projectile which

Lizardi's backpack was then discovered in Luquillo, down
the road from Hernández's home, at a location also just a mile
from where Casey lived.

It contained clothes and a towel with

hair on it that law enforcement concluded was not Casey's, although
no tests were conducted to ascertain whose hair it was.

A few

days later, Lizardi's body was also found in Luquillo, down a hill
in a wooded area behind an abandoned structure that contained
traces of blood.

B. Procedural History
In February 2007, a grand jury returned a three-count
indictment charging Casey with (1) carjacking with the intent to
cause death or serious bodily injury (18 U.S.C. § 2119(3)); (2)
possession, use, discharge, carrying of firearms during a crime of
violence resulting in another's death (18 U.S.C. § 924(j)); and

That July,

the government filed a notice of intent to seek the death penalty.
Pretrial proceedings took place over six years, mostly
concerning the death penalty. Suppression motions were heard in
the fall of 2011 and rulings issued in January 2013.

Casey moved

to suppress the evidence discovered in his bedroom on the ground
that his grandparents had neither actual nor apparent authority to
consent to the warrantless search, arguing the search was unlawful
and the evidence it yielded inadmissible.

Finding that the room

routinely remained unlocked and that Casey's grandparents had
permission to enter it on a regular basis, the district court
denied this motion.

Casey also moved to suppress Algarín's photo

array identification from the Fajardo parking lot; statements
elicited from him allegedly in violation of his Miranda rights;

Trial then commenced

in March.
Casey argues that a number of erroneous rulings at trial
amounted to a violation of his right to confrontation and to
present a defense.

In particular, he contends it was improper to

preclude evidence which would have shown that the PRPD declined to
properly investigate the possible involvement of Hernández, the
dealer with whom the August 1, 2005, drug buy had been arranged,
in Lizardi's death.

The subject of such purported evidence

included a PRPD internal investigation into its own possible
negligence in the planning and execution of Lizardi's undercover
operation.

After nine days of trial, the jury returned a verdict of
guilty as to all counts but rejected the death penalty.

of conviction was entered on June 13, 2013, and Casey was sentenced
to life in prison.

This appeal followed.
II.

Discussion

A. Prosecution's Use of Peremptory Challenges
Casey, a black American transplant from Brooklyn to
Puerto Rico, argues the district court erred in finding no equal
protection violation in the government's exercise of peremptory
challenges to exclude three black persons from the jury, he claims,
solely on the basis of race.
1.

Batson Challenge

In Batson v. Kentucky, the Supreme Court reaffirmed the
longstanding

principle

that

a

criminal

defendant's

equal

protection rights are violated when jury selection at his trial is
"affected by invidious racial discrimination."

The "[e]xclusion of

jurors,"

stated

Batson,

"constitutes a primary example of the evil the Fourteenth Amendment
was designed to cure."

Batson v. Kentucky, 476 U.S. 79, 85 (1986).

While Batson initially focused on whether the defendant or an
excluded juror was part of a cognizable racial group, subsequent
cases broadened Batson doctrine to encompass an individual juror's
right not to be discriminated against -- making the relevant query
-8-

Case: 13-1839

Document: 00117009226

whether "a peremptory challenge was based on race."

Entry ID: 6005530

See Sanchez

v. Roden, 753 F.3d 279, 292 (1st Cir. 2014) (quoting Snyder v.
Louisiana, 552 U.S. 472, 476 (2008)).
Batson outlined a three-part burden-shifting framework,
a "Batson challenge," through which a defendant can dispute the
government's use of peremptory strikes as racially motivated and
demonstrate an equal protection violation.

See Foster v. Chatman,

No. 14-8349, 2016 WL 2945233 at *8 (U.S. May 23, 2016).

The

defendant is required to first make a prima facie showing that
race formed the basis for a peremptory challenge.

The trial court

must consider all relevant "circumstantial and direct evidence of
intent as may be available" to determine whether an inference of
racial motivation may be drawn.

Batson, 476 U.S. at 93, 96

(quoting Arlington Heights v. Met. Hous. Dev. Corp., 429 U.S. 252,
266 (1977)).

For instance, a "pattern" of strikes against black

jurors, a "prosecutor's questions and statements during voir dire
examination and in exercising his challenges," Sanchez, 753 F.3d

strike may shed on an earlier one, can support an inference of
discriminatory purpose, Snyder, 552 U.S. at 478 (noting that
persisting doubt as to a particular strike requires the court to
consider another strike for the bearing it might have on the
previous challenge); United States v. Charlton, 600 F.3d 43, 55

permissible individual strikes may need "a second look" if, when

Here, the district court did not specifically find, but
rather assumed, that Casey satisfied his burden at Batson's first
step to show a prima facie case of discrimination.

According to

Casey, however, the district court nevertheless committed clear
error at the third step by accepting at face value the prosecutor's
race-neutral explanations, rather than offering the defense an
opportunity to expose the explanations as pretextual.

While we

conclude a Batson error was in fact committed here, because the
error was without doubt harmless, we affirm.

Standard of Review for Batson Challenge Ruling

We review a district court's factual determination that
the government was not motivated by race for clear error, and may
reverse only where we arrive at a "definite and firm conviction
that a mistake has been committed."

United States v. González-

Meléndez, 594 F.3d 28, 35 (1st Cir. 2010); Charlton, 600 F.3d at
50. We are mindful that only the trial court observed first-hand
"the demeanor of the attorney who exercise[d] the challenge, along
with whether [each stricken panelist's] demeanor can credibly be
said to have exhibited the basis for the strike."

v. Mensah, 737 F.3d 789, 796 (1st Cir. 2013) (internal quotation

Crediting the government's race-neutral explanations for
its peremptories, the district court denied Casey's challenge.

It

held that because Juror 175 had not self-identified as black, Casey
failed to make a prima facie case of purposeful discrimination;
but that even if she was black, "she expressed reluctance to apply
the death penalty in cases where the victim was not a child,
elderly, or otherwise a defenseless victim."

As for Juror 182,

who self-identified as "Catholic (Black)," the district court
looked to his statement on his questionnaire and at voir dire that
the death penalty "is inhuman."

Finally, with regard to Juror

354, who first identified as Hispanic and later modified this to
"Hispanic black," the district court concluded the government's
peremptory strike was not racially motivated because her response
to a hypothetical in which a defendant killed an unarmed law
enforcement officer was that life in prison, not the death penalty,
would be the appropriate punishment; Juror 354 did, however, say
she could take into account other aggravating factors to consider
the death penalty.

This was fortunate because the record demonstrates a

even

though

for

Casey.

Specifically, the parties and the district court labored under the
misimpression that the defendant must be of the same race as the
stricken juror in order to raise a Batson challenge.

The district

court even denied one of Casey's challenges on this very basis.
This runs afoul of Powers v. Ohio.

499 U.S. 400, 402 (1991) ("[A]

criminal defendant may object to race-based exclusions of jurors
effected

through

peremptory

challenges

whether

or

not

the

defendant and the excluded juror share the same races.").
The error was, nevertheless, harmless.

Casey, whose

Batson challenge was based almost entirely on numbers alone,
stresses that the prosecution's use of 3 of its 14 peremptory
challenges on blacks "strongly suggests that something more than
chance was at work."

But the venire contained very few persons

who self-identified as black to begin with, especially after the
various excusals and stipulated dismissals.

This is materially

different from where "the numbers are larger and the pattern is
inescapably apparent."

Mensah, 737 F.3d at 801.

Casey's arguments on appeal misstate the statistics at
the crux of his argument.

For instance, he claims the government's

use of the 3 of its 14 peremptories against black prospective
jurors constituted 42 percent of its peremptories; the actual
-14-

figure is 21 percent.

the

And just 3.7 percent of

that pool (12 regular jurors and 5 alternates, 17 altogether out
of the 457-person venire) made it onto the jury.

"Thus, as is

common, the numbers considered in isolation are inconclusive in
determining whether [Casey] met his burden on step one."

Schneckloth

v. Bustamonte, 412 U.S. 218, 245-46

Common authority is not, however, to be implied from the
mere property interest a third party has in the property.

See

Stoner v. California, 376 U.S. 483, 487-88 (1964) (finding the
warrantless search of a hotel room by consent of the hotel clerk,
absent the guest's consent, unlawful); Minnesota v. Olson, 495
U.S. 91, 96-97 (1990) (finding that a defendant's status as an
overnight guest in the upper unit of a duplex home was sufficient
for him to claim a protected privacy interest in the premises,
even though he was not given a key or left alone in the unit, and
did not pay for his stay).
Rather, common authority arises from having a shared
privacy interest in the premises or effects to be searched.

United

States v. Matlock, 415 U.S. 164, 171-72 (1974) (reasoning that
through mutual use -- as opposed to mere joint access -- of the

Background
The parties agree that the day after Casey's arrest and

while he was in custody, PRPD and FBI agents obtained consent from
Casey's grandparents, the Riveras, to search Casey's bedroom in
their house, where Casey had resided since 2002.

PRPD agents

found the room door open, and taped it off upon arrival to preserve
the room for the FBI to inspect.
The district court was faced with conflicting testimony
from Mr. Rivera, on the one hand, and Agent Marrero and Lieutenant
Nazario of PRPD and FBI Special Agent Villareal, on the other.

It

decided to afford "more credence to the testimony provided by [the
officers than by] Rivera."

In doing so, it reasoned that Mr.

Rivera had contradicted himself about his employment status and
admitted he had illegally avoided paying taxes, and further that
while Mr. Rivera had motive to lie to protect his grandson, the
testifying officers had no similar stake in the case.
At the suppression hearing, Mr. Rivera testified that
the room was used only by Casey and contained only his personal
belongings; that Casey paid rent whenever he was working; that the

According to Agent Villareal, Mr. Rivera said Casey "could

not afford to maintain his own household and provide his own food,"
so he received lodging and food "for free" with the Riveras.

Agent

Villareal further recalled that, when asked whether Casey lived in
a specific room of the house, Mr. Rivera responded that Casey
indeed resided in a room in the "posterior part of the house."
Its "door did not have a lock," said Mr. Rivera, and both Riveras
"had free access to the room at all times, since it was their
residence."

Agent Villareal's testimony then shifted to his

conversation with Mrs. Rivera, who provided him with aligning
information.

She told Agent Villareal that Casey "did not have

enough income . . . to support himself and had to live with [the
Riveras] . . . rent free and was provided food by [the Riveras]."
Mrs. Rivera also said to Agent Villareal that Casey's room "did
not have a lock" and she "was free to come and enter at will."
Agent Marrero, who arrived at the Rivera home before the
FBI, similarly testified that when she got there, Mrs. Rivera said

she had "no problem" with Agent Marrero's presence, or the search
of the residence to which Mr. Rivera had given consent at the
police station.

Agent Marrero further recalled finding the door

to Casey's room open, and taping it off to preserve evidence while
she waited for the FBI to arrive.

When Agent Marrero asked who

could go into and use the room, Mrs. Rivera replied, "[o]nly the
three of them."
While Agent Nazario did not specifically recall Mr.
Rivera's response about who could enter the room, he, like the
other agents, testified that Mr. Rivera readily offered consent
and gave Agent Nazario no reason to believe he lacked authority to
do so.

"[O]n the contrary," testified Agent Nazario, "Mr. Rivera

always identified himself as the owner of the house and as the one
who can authorize [a search]."

Agent Nazario furthered that Mr.

Rivera "represented himself to be . . . the one that ordered people
around there."

The district

D.

Discussion
Casey argues that his grandparents did not have the

requisite authority to consent to the search.

He bases this solely

on Mr. Rivera's on-the-stand statements, which differ materially
from what the Riveras told officers prior to the search at the
Rivera home.

Indeed, the law enforcement officers recount that

the Riveras affirmatively indicated they could freely enter and
exit the room and treated it as a part of their home, and never
once did the Riveras do or say anything to suggest otherwise.
There was no clear error in giving greater credence to
the three agents' testimony than to Mr. Rivera's.

While their

statements do differ materially from Mr. Rivera's assertions on
the stand, the district court offered reasoning to back up its
determination: "Rivera . . . has close ties to defendant . . .

changed his tune between the time the officers asked to search
Casey's room -- when he readily shared that he had full access to
the room and authority to consent to its search –- and the moment
he took the stand at the suppression hearing.

That Mr. Rivera

contradicted himself about his employment status provided further
reason to discredit his on-the-stand statements.
The question is thus whether the district court was
correct that the officers' testimony established that the Riveras
had common authority to consent to the search of Casey's bedroom.
The officers appear to have asked the Riveras very few questions.
We encourage law enforcement officers in the future to obtain
sufficient facts about a given living situation to not only give
them the ability to assess the validity of third-party consent
before initiating a search, but also to allow a reviewing court to
make an assessment in the event that consent is later challenged.
Nevertheless, the facts that the officers had before
them at the time of the search gave them sufficient reason to
believe that the Riveras had full "run of the house," see United
States

that between a hotel clerk and guest, see Stoner, 376 U.S. at 488.
We thus agree with the district court that the Riveras had apparent
authority to consent to the search, and we do not reach the
question whether the Riveras had actual authority as well.
In so holding, we note that the facts of this case are
different from those in United States v. Whitfield, 939 F.2d 1071
(D.C. Cir. 1991), one of the cases on which Casey relies.

Entry ID: 6005530

Here, by contrast, the

statements made by the Riveras when questioned by the officers
permitted the inference that there was an arrangement in the house
whereby the Riveras could come and go from Casey's room at will.
Finally, Casey's contention that the Riveras' consent
was not voluntary fails.

While Mr. Rivera did testify that the

presence of numerous officers at his home made him nervous, the
record contains no suggestion that Mr. Rivera was coerced or
threatened, or that he did not comprehend the officers' questions.
He gave consent both at the police station before agents arrived
at his home, and again just before the search commenced.

slim build and black hair."

As the district court noted, while

Casey had the darkest complexion among them, each individual could
have been described as black, and they shared relatively similar
facial features, a near-identical haircut, and groomed eyebrows.
See DeCologero, 530 F.3d at 62 (while officers creating a photo
array must make "every effort reasonable under the circumstances"
to conduct a "balanced representation," they need not "search for
identical twins").

The array displayed no names, and bore a

disclaimer in Spanish and English stating that the person the
witness saw may or may not appear among the presented pictures.
Agent Moulier testified the array was prepared according to "policy
about the race, sex, skin color of the person," based on the
descriptions Algarín and other parking lot witnesses gave of the

ticket, which prompted Algarín to ask for the driver's name,
address and phone number for a lost ticket form.

The driver,

furthermore, was unable to provide his license or registration
documents, and told Algarín to keep the change from a twentydollar bill tendered for a parking fee Algarín testified could not
have been more than two or three dollars.
Also, while general, Algarín's description of the driver
is consistent with his selection from the photo array, made a few
weeks after his earlier contact with a driver leaving a significant
gratuity.

See id. at 61-63 (finding no issue with an array

The

district court thus did not err in denying Casey's motion to

Casey asked to see his grandfather and told Agent Marrero he was

Casey was, in the meantime, transferred to

the Luquillo precinct, and then to FBI premises in Ceiba, shortly

In this same conversation, Casey also advised Peña to
obtain employment certificates from his social worker and change
the dates on them to obtain a loan.

Their exchange also included

reference to some prior offense "when they got us with drugs and

Casey asserts this entire interaction comprised an

unconstitutional interrogation, and none of its content should
have been admitted.

Casey's motion to suppress the statements made to Agent Marrero at
Ceiba and those overheard by Agent Vachier-Serrano.

contended to no avail that all his statements to Agent Marrero
should have been suppressed because he was assaulted upon arrest,
leading him to waive his

Miranda

rights involuntarily.

The

district court found no evidence to substantiate the purported
assault, and ruled that even had Casey been assaulted, the waiver
he gave at PRPD headquarters was voluntary.

Finding that Casey

had, however, asserted his right to counsel during his interview
with Agent Marrero at Ceiba just before Agent Marrero appealed to
Casey's sensibilities as a father, the district court suppressed
Casey's statements made thereafter.

Finally, the district court

concluded that Casey's conversation with Peña was not a custodial

that

the

On appeal,

Casey contends that questioning him after both instances in which
he asserted his Miranda rights not to speak was impermissible under

Because it was

impossible to tell, he argues, no part of the conversation should

There was no clear error in placing

Casey's invocation of his right to an attorney after his statement
that Lizardi was "maybe alive" or "maybe dead" but before Agent
Marrero's appeal to his values as a father, and admitting only
part of the conversation accordingly.

Agent Marrero testified as

Finally, the district court was correct to conclude that
Casey's conversation with his wife was not the result of an

Even if his assertions on appeal about his earlier invocations
of the right to remain silent are accurate and not waived,
statements made after a defendant has invoked his right to remain

between interrogations, the provision of fresh Miranda warnings,
the scope of the follow-up interview, and the zeal of the officers

States v. Hsu, 852, F.2d 407, 410 (9th Cir. 1998). It is not in

indication that the officers approached him with any particularly
coercive tactics.

(1st Cir. 2008).

United States v. Jackson, 544 F.3d 351, 357

Casey offers no evidence that the FBI brought

Peña in for interrogation purposes.

Rather, the record reflects

that she had been following Casey to the various locations he was
taken and wanted to meet with him of her own volition.

Casey also does not dispute

that he was fully aware Agent Vachier-Serrano was present and

We therefore affirm the district court's order

statements he made while in custody.
VI.

Challenge to Admission of All Statements Due to Lack of
Prompt Presentment
Casey argues for the first time on appeal that all of

his statements should have been suppressed for failure to promptly
bring him before a magistrate judge.

He admits, however, that he

declined to raise this argument below.

be raised prior to trial, and failure to do so in a timely manner
constitutes waiver.

We therefore deem this argument waived.

VII. Challenge To Alleged Trial Errors Infringing Casey's Right
to Confrontation and to Present a Defense
Next, Casey urges that the district court committed a
series of errors throughout his trial, including: (1) admitting
irrelevant and unduly prejudicial evidence under Federal Rule of
Evidence 404(b), specifically statements he made to Peña while in
custody and photographs of Lizardi's body; (2) limiting Casey's
cross-examination of agents about investigation efforts prior to
August 1, 2005; and (3) rejecting under Daubert the preliminary
report from an internal PRPD investigation and its recommendation
of sanctions against several involved officers.
A.

Standard of Review
Preserved evidentiary objections are reviewed under an

abuse of discretion standard.

This court must nevertheless affirm

reversal, may have a cumulative effect, rendering the trial unfair.
United States v. Sepúlveda, 15 F.3d 1161, 1195-96 (1st Cir. 1993).

B.

Irrelevant and Unduly Prejudicial Evidence
1.

Federal Rules of Evidence 402, 403, and 404(b)

Rules 401 and 402 provide that all "relevant" evidence,
or that which has a "tendency to make a fact more or less probable
than it would be without the evidence," is admissible.

However,

under Rule 403, "[t]he court may exclude relevant evidence if its
probative value is substantially outweighed by a danger of one or
more of the following: unfair prejudice, confusing the issues,
misleading the jury, undue delay, wasting time, or needlessly
presenting cumulative evidence."

Under Rule 404(b), evidence of

past wrongs is not admissible character evidence to demonstrate a
defendant's propensity to behave in a certain manner.
2.

Application
a.

Casey's Statements to Peña

Agent Vachier-Serrano first testified as to statements
Casey made to his wife about falsifying an employment certificate,
described above.

The court denied a hearsay objection and granted

a relevance objection.

It then gave a limiting instruction to the

jury, stating that because the "references to fraudulent conduct

Casey's relevance objection was overruled.

refusal to strike the testimony about falsifying an employment

Casey contends

this evidence had no probative value, and was merely introduced

There was no plain error in finding to the contrary.
The limiting instruction as to Casey's instructions to Peña to
falsify an employment certificate made clear to the jury that the
fraudulent conduct Casey was describing to Peña had no bearing on
this trial.

See United States v. Williams, 717 F.3d 35, 42 (1st

Cir. 2013).

Case: 13-1839

Nor does the court's rationale to permit Agent VachierSerrano's testimony about the prior drug case constitute an abuse
of discretion.

While it is conceivable that Casey's statements

about the prior drug offense perhaps reflected his consciousness
of guilt, any such error was likely harmless.

Other evidence

alerted the jury to Casey's ties to the criminal underworld; it
was, indeed, no secret that Casey led the police around for several
hours just after his arrest to point out to them other drug
traffickers with possible tips on Lizardi's whereabouts.

It is

doubtful that knowledge of an unspecified prior drug offense could
convince a jury to convict Casey of the charges in this case.

It is more than plausible that the first five photos
corroborated various pieces of testimony:

to Peña that the body would be difficult to find; and the time it
took to locate the body.

The jury received instruction prior to

The last two photos might likewise have corroborated

testimony that the body had been left outdoors for a few days.

Casey also argues abuse of discretion in keeping him
from impeaching Agosto based on purportedly conflicting statements
about whether Lizardi, Casey and Hernández met a few days before
the events of August 1, 2005.

On the stand, Agent Agosto testified

Hernández and Lizardi did not meet on July 28, 2005, days before
the events of August 1.

Defense counsel moved unsuccessfully to

Case: 13-1839

introduce, as a prior inconsistent statement, a report prepared in
2005 by Agent Agosto documenting that such a meeting did occur, on
information Lizardi had shared with Agosto at that time.

While

the district court excluded the report, it did allow defense
counsel to question Agent Agosto about the July 28 meeting.

Agent

Agosto's answers revealed that Lizardi, with Casey at the Holiday
Inn, spoke to Hernández by phone on July 28 to plan the August 1
drug buy (although Agent Agosto maintained that Hernández was not
present in person).
Any error by the court here was certainly harmless.
Casey was able to use Lizardi's telephone records to impeach Agent
Agosto's testimony to show that Lizardi did speak to Hernández on
July 28.
2.

Commander Morales

The district court similarly did not err in limiting
Morales's testimony to events on August 1, 2005, and thereafter as

precluded him from contending that authorities "dropped the ball

from a non-expert witness, it did permit Casey's counsel to elicit
a critical point on cross-examination -- that hair found on the
discovered black backpack did not belong to Casey or Lizardi (with
the caveat that the results could have been affected over time),
but was not tested against Hernández.

its discretion in precluding him from presenting a police practices

While Casey stresses on appeal the relevance of Dr.

standards or policies for undercover work; and that he was not
even aware whether the FBI or PRPD were part of the Commission for
Accreditation of Law Enforcement Agents.

reduced to orientation training), and whether it represented a
final administrative determination.
Moreover, it became clear that Agent Agosto had never
seen this preliminary report, and thus could not be impeached with
its contents.

Finally, the government was unable to demonstrate

that the officers whose statements appeared in the report had
personal knowledge of the events they were describing -- or, for
that matter, that Agent Rodríguez-Torres had sufficient personal
knowledge.

See Fed. R. Evid. 602.

The district court thus did

not abuse its discretion in excluding testimony concerning the
Rodríguez-Torres report.
F.

Cumulative Effect
Casey argues the cumulative impact of this purported

litany of errors precluded him from receiving a fair trial.

Even

if some, or all, of the above decisions were mistakes, they appear
to concern evidence tangential to the government's case against
Casey.

Indeed, even had Casey been able to implicate Hernández

as the more likely perpetrator with some of the above evidence, or
to undermine the PRPD's credibility, he would not have been able
to eviscerate the positive evidence against him.

Before trial, expert Brendan Shea had prepared a report

that DNA from the twenty-dollar bill matched Lizardi; DNA from the
floors and swabs of the abandoned structure matched Lizardi; and
Lizardi was "potentially the major contributor" of DNA on the flipflops found in Casey's bedroom.

IX.

Denial of Recusal Motion

It may nevertheless be worth briefly examining how this move
might have been an intended tactic of Casey's trial strategy. At
closing, Casey's counsel neatly summed up their theory of the case:
that the PRPD and FBI investigation was so affected by "tunnel
vision" that it leapt to pin Lizardi's death on Casey without
adequately investigating other potential suspects, chiefly
Alexander Hernández. It was in service of this narrative that,
throughout the trial, Casey's counsel highlighted how the FBI could
have collected more DNA samples and conducted more DNA tests that
could have implicated Hernández. One such instance, she argued,
was when the blood on Casey's sandal was revealed to contain "a
mixture of DNA," indicating "more then [sic] one contributor," but
was not subjected to further analysis. Such a strategy, we think,
hinged on the accuracy and admission of the FBI's DNA analyses.
There otherwise would have been little reason for the jury to
believe that more testing would have led the FBI to Hernández.
Although this is mere speculation on our part, Casey, it appears,
had plausible reason to welcome admission of the government's DNA
reports.

believes no party will gain an advantage as a result.

Standard of Review
A district court's decision not to recuse itself is

reviewed for abuse of discretion.
F.3d 52, 62 (1st Cir. 2009).

United States v. Pulido, 566

This court must sustain the district

court's ruling unless it can find the decision was not reasonable
and is unsupported by the record.

Background
The district court maintained that communications with

the documents together, or had any other substantive exchange.
