In cases in which defendants are

accused of trafficking in narcotics, drug quantity is often both
an element of the offense and a critical integer in the sentencing
calculus.

These appeals illustrate that duality and, at the same

time, serve to explicate the shifting standards of proof that
pertain.

Because

the

court

below

applied

these

standards

appropriately, we affirm both of the challenged convictions and
two of the three challenged sentences.

With respect to the third

sentence, though, the government concedes that the district court
relied on too weak a foundation in classifying the defendant as a
career offender and we are not persuaded by the government's
attempt to brand the error harmless.

We therefore remand that

sentence for further proceedings consistent with this opinion.
I.

BACKGROUND
We start with an overview of the case, drawing relevant

facts from the trial transcripts, line sheets of recorded telephone
calls introduced into evidence, and (where appropriate) undisputed
portions of the defendants' presentence investigation reports.
This case has its roots in an investigation into drug
dealing in and around Worcester, Massachusetts, commenced by the
Drug Enforcement Administration (DEA) and local police officers.
The probe initially focused on defendants James Dunston and Sergio
Hernandez.

Its scope later expanded to include defendant Anthony

Wooldridge.

All three were charged with conspiring to possess

The district court ordered the probation department to

At the

disposition hearings, the court adopted the reports without change
and classified all three defendants as career offenders under the
sentencing guidelines.

It found Wooldridge responsible for at

least 840 grams of crack cocaine and sentenced him to a 132-month
term of immurement.

With respect to Dunston and Hernandez, the

court found each of them responsible for at least 2.8 kilograms
(2,800 grams) of crack cocaine; sentenced Dunston to 144 months'
imprisonment; and sentenced Hernandez to 162 months' imprisonment.
These timely appeals followed.
II.

ANALYSIS
The defendants' appeals have been consolidated, and we

turn first to the claims of error that implicate their convictions.
From that point, we proceed to their claims of sentencing error.
A.

Lay Opinion Testimony.

Dunston contends that the district court should not have
allowed Agent Boyle to testify about the meaning of slang terms
and jargon used in the course of the wiretapped conversations.

He

submits that although Boyle may have been qualified to give some
lay opinion testimony, the government failed to erect an adequate

Case: 15-1812

Document: 00117129479

Page: 7

Entry ID: 6076235

foundation for his interpretations of particular slang terms.

To

illustrate his point, Dunston notes that Boyle was allowed to
testify that the word "tweezy" referred to crack cocaine and that
the phrase "step up a yard" referred to turning powder into crack.
In

Dunston's

view,

Boyle's

familiarity

with

the

defendants'

conversations did not qualify him to give an informed opinion about
the meaning of these and other specific phrases used within those
conversations.

We do not agree.

All three defendants raised this issue below, but only
Dunston pursues it on appeal.

Objections to the admission of

evidence are reviewed for abuse of discretion.

See United States

v. Valdivia, 680 F.3d 33, 50 (1st Cir. 2012).

The parties agree

that Agent Boyle's testimony should be considered lay opinion
testimony.

Hence, Federal Rule of Evidence 701 controls.

See id.

Rule 701 permits the admission of lay opinion testimony "rationally
based on the witness's perception" that would help the factfinder
"determin[e] a fact in issue."
Application of Rule 701 in the drug-trafficking context
is not novel: "we have long held that government witnesses with
experience in drug investigations may explain the drug trade and
translate coded language" for factfinders through lay opinion
testimony.

United States v. Rosado-Pérez, 605 F.3d 48, 56 (1st

Cir. 2010); accord United States v. Hoffman, 832 F.2d 1299, 1310
(1st Cir. 1987) (holding that "interpretation of codes and jargon

used in the drug trade can be supplied through one experienced in
the field").

Such testimony is especially useful where, as here,

it can afford the factfinder the benefit of specialized knowledge.
See United States v. Albertelli, 687 F.3d 439, 446 (1st Cir. 2012).
Of course, such interpretive testimony must be anchored
in the witness's personal experience in the field, see Hoffman,
832 F.2d at 1310, and his experience-based understanding of the
meaning of the terms used, United States v. Prange, 771 F.3d 17,
28 & n.3 (1st Cir. 2014).

Put another way, "an interpretation of

a phrase or reference ought to be explicable" — a standard that
typically requires the witness to point to similar statements
surrounding similar events.

Albertelli, 687 F.3d at 450.

In the case at hand, the government erected a sturdy
foundation for Boyle's testimony.

The record reflects that Boyle

had a twenty-four-year career in law enforcement, with significant
experience in undercover drug investigations.

He had received

specialized training in narcotics enforcement, had participated in
over fifteen wiretap investigations, and had supervised more than
twenty other such investigations.

In this particular probe, Boyle reviewed nearly all of
the 30,000 calls and texts collected during the wiretaps.

He not

only drew on his extensive experience to inform his understanding
of specific slang terms but also took into account the context in
which those terms were used.

Boyle explained that he often

listened to "several calls leading up to" the use of a given bit
of slang as well as "conversations that would take place after
that" to ensure his understanding.
Confronted with objections, the district court prudently
allowed defense counsel to conduct a voir dire and question Boyle
about his credentials, his experience, and his knowledge.

This

additional safeguard, coupled with Boyle's cross-examination by
all three defense attorneys, mitigated any risk of unfair prejudice
from his testimony.

See United States v. Henry, ___ F.3d ___, ___

B.

Sufficiency of the Evidence.

The next leg of our journey takes us to Dunston's and
Wooldridge's claims that the district court lacked sufficient
evidence to find them guilty of the charged offense.

These claims

share a common focus: they are aimed at the district court's
finding, at trial, that at least 280 grams of crack cocaine was
"attributable and reasonably foreseeable" by the defendant making
the claim.

Such a defendant-specific finding is an element of the

offense of conviction: it means that a defendant cannot, simply by
reason of his membership in a conspiracy that traffics in large
amounts of drugs, automatically be "saddled with the full weight
of the conspiracy's wrongdoing."

United States v. Sepulveda, 15

F.3d 1161, 1197 (1st Cir. 1993).

He can only be held responsible

for drugs that he "personally handled or anticipated handling," as
well as "drugs involved in additional acts that were reasonably
foreseeable by him and were committed in furtherance of the
conspiracy."

Id.

Here, the district court held a bench trial on the drugweight issue — a trial that was necessary because any fact that
increases the mandatory minimum sentence for an offense must,
absent a plea or a stipulation, be submitted to a factfinder to be
determined beyond a reasonable doubt.

The ultimate question is whether,

after viewing the evidence in the light most hospitable to the

We begin with Dunston and then move to

Wooldridge.

1.

Dunston.

Page: 12

Date Filed: 03/15/2017

Entry ID: 6076235

Dunston contends that the court's finding

that he was responsible for at least 280 grams of crack cocaine
was plucked out of thin air.

Pointing out that the authorities

never seized any of the drugs to which he alluded in the wiretapped
conversations, he insists that it remains unclear how much powder
was converted to crack.
Dunston is whistling past the graveyard.

The government

presented evidence linking Dunston to at least eight separate
transactions.

We need examine only two of these occurrences to

defuse Dunston's attack.
On June 26, the government intercepted a telephone call
in which Dunston and Hernandez discussed their plans to cook 200
grams of powder cocaine recently purchased from Wooldridge.

The

two men split the contraband, and Dunston told Hernandez that he
was going to "step up a yard right now and see what it is."

This

meant, Agent Boyle testified, that Dunston intended to convert 100
grams of powder into crack.

reference to drying the product was also consistent with making
crack.
When judges sit as factfinders, they are not obliged to
put their common sense into cold storage.

Given the wiretaps and

Boyle's testimony, the district court surely had a rational basis
for

finding,

beyond

any

reasonable

doubt,

that

Dunston

was

responsible for at least 200 grams of crack stemming from the June
26 events.

For one thing, the court supportably could have found

Dunston responsible for the 100 grams that he himself cooked.

For

another thing, the court supportably could have found that the
remaining 100 grams, retained by Hernandez, was to be converted
from powder to crack as part of the conspiracy and that the
conversion was reasonably foreseeable to Dunston.1
Dunston protests.

He says that there is no evidence

that this latter 100 grams of powder was actually converted to
crack and that this part of the district court's drug-quantity
calculation was faulty because it implicitly assumed that 100 grams
of powder cocaine, when converted, would yield 100 grams of crack

1

For example, the court heard evidence that once Dunston told
Hernandez that he "got back 2 . . . extra grams" after cooking the
powder, Hernandez responded, "You should have done mine." Dunston
replied, "You're the only one that didn't want me to do yours!"
and indicated that Hernandez had mentioned planning to cook his
powder in a particular type of pot. Several hours later, Hernandez
called a third party and asked to use his kitchen.

cocaine.

Page: 14

Date Filed: 03/15/2017

Entry ID: 6076235

He insists that, even in optimal conditions, 100 grams

of powder cannot be converted into more than 89.2 grams of crack.
This attack misfires.

The court had before it evidence

that, on both June 26 and June 29 (discussed infra), Dunston
himself had performed conversion operations and had gotten better
than a one-to-one yield.

Given that evidence, the court was

entitled to apply a one-to-one conversion ratio in its appraisal
of the conspiracy's output.2
The court also heard the particulars of a transaction
that occurred on June 29. On that date, the government intercepted
a call between Hernandez and a third party, during which Hernandez
bought 200 grams of powder cocaine.

Just over two hours later,

Dunston called Hernandez to inform him that he planned to "do the
whole thing together."

He subsequently reported that the result

was "206 wet," and yellow in color, but quickly turning white.
Given

this

evidence

and

Boyle's

explanatory

testimony,

the

district court could have attributed, beyond any reasonable doubt,
an additional 200 grams of crack to Dunston.

After all, proof

We note, moreover, that the statute of conviction
criminalizes conspiracies involving the possession and intended
distribution of "280 grams or more of a mixture or substance
. . . which contains cocaine base." 21 U.S.C. § 841(b)(1)(A)(iii)
(emphasis supplied).
Whether the weight of the defendants'
products came from pure crack cocaine or crack combined with water
or some other adulterant is beside the point: the record reflects
that the defendants conspired to possess and distribute a "mixture
or substance" that contained cocaine base. Id.

beyond a reasonable doubt does not require proof to an absolute
certainty.

See United States v. Lasseque, 806 F.3d 618, 623 (1st

Cir. 2015), cert. denied, 136 S. Ct. 1472 (2016).
Dunston counters that the government offered no direct
or tangible evidence that this batch of cocaine ever existed.

But

it is old hat that proof of a defendant's guilt can be based, in
whole or in part, on circumstantial evidence.

See United States

v. George, 841 F.3d 55, 63 (1st Cir. 2016); United States v.
Williams, 717 F.3d 35, 39-40 (1st Cir. 2013).

In this instance,

the district court, qua factfinder, drew a series of reasonable
inferences from the evidence, and its conclusion that Dunston was
responsible for this additional 200 grams of crack is unimpugnable.
For these reasons, Dunston's conviction must stand.
2.

Wooldridge.

The record also provides ample support

for the district court's decision to attribute at least 280 grams
of crack cocaine to Wooldridge.

Wooldridge was arrested with

ninety-three grams of crack on his person.

In addition, there was

cogent evidence that Wooldridge sold his codefendants the 200 grams
of powder cocaine mentioned in the June 26 conversation.

As

explained above, 200 grams of powder could be found, beyond a
reasonable doubt, to equal 200 grams of crack.

Because the

production of crack was a reasonably foreseeable act in furtherance
of the conspiracy, the district court did not err either in finding
that Dunston and Hernandez converted their shares of the powder

sold by Wooldridge into crack or in holding Wooldridge responsible
for a corresponding amount of crack.

See Sepulveda, 15 F.3d at

1197.
In an effort to stave off this conclusion, Wooldridge
insists that he was not yet part of the charged conspiracy when he
sold drugs to his codefendants at the end of June.

history, and we reject it.

This is revisionist

Wooldridge pleaded guilty to being a

member of the conspiracy beginning in August of 2011 — long before
the sale occurred.

He is bound by his plea.

See United States v.

Laracuent, 778 F.3d 347, 351 (1st Cir.), cert. denied, 135 S. Ct.
2875 (2015).
That ends this aspect of the matter.

We conclude that

the evidence was sufficient to allow the district court to find
beyond a reasonable doubt that at least 280 grams of crack were
attributable to Wooldridge.

Consequently, his conviction must

Dunston was subject to the career offender guideline.
See USSG §4B1.1(a).

The court below set his guideline sentencing

range (GSR) at 262-327 months and sentenced him appreciably below
the bottom of that range.

A defendant who challenges a below-the-

range sentence as substantively unreasonable must carry a heavy
burden.

The greater the drop from the bottom of the

It explained that a significant period of

Given the

scope and duration of the conspiracy, the force of this explanation

The court added, though, that "incarceration

at or near the advisory guideline range seems to be more than what
is necessary to meet the goals of sentencing."

For that reason,

it executed a sharp downward variance.
Despite the court's seeming leniency, Dunston assails
the result, arguing that his ultimate sentence was skewed by a
"mechanical application" of the career offender guideline.

This

argument is constructed out of whole cloth: it overlooks the
undeniable fact that the sentencing court's downward variance was
anything but mechanical, yielding a sentence almost ten years below

designation as a career offender, see USSG §4B1.1(a), resulted in
a GSR of 262-327 months.

The district court proceeded to impose

a below-the-range sentence of 132 months.
Although the district court varied downward from the
guideline range, any error in calculating that range would likely
be material on appeal.

See Molina-Martinez v. United States, 136

S. Ct. 1338, 1346 (2016) ("In most cases a defendant who has shown
that the district court mistakenly deemed applicable an incorrect,
higher Guidelines range has demonstrated a reasonable probability
of a different outcome.").

Here, however, the district court's

drug-quantity determination (and, thus, its configuration of the
GSR) is not clearly erroneous.
The district court identified three transactions that
linked Wooldridge to well over 840 grams of crack cocaine.

First,

Wooldridge sold powder cocaine to Hernandez and Dunston at the end
of June and, as discussed above, see supra Part IIB, that sale
formed a solid basis for a finding attributing approximately 200
grams of crack cocaine to him.

Second, the court supportably tied

Wooldridge to a purchase of 300 grams of powder cocaine that
occurred on July 31.3

The record includes discussions among all

three defendants about the purchase and about their plans to

3

Indeed, Wooldridge admits that the ninety-three grams of
crack cocaine found on his person when he was arrested was his
share of this purchase.

convert the powder into crack.

Date Filed: 03/15/2017

Entry ID: 6076235

That evidence, coupled with the

court's permissible use of a one-to-one conversion ratio, was
sufficient to ground attribution of 300 grams of crack cocaine to
Wooldridge.
Third, and finally, the court reasonably attributed an
additional 497 grams of crack cocaine to Wooldridge with respect
to events occurring on August 31.

At that time, federal agents

seized a package sent by Cruz (in Puerto Rico) to an acquaintance
of Hernandez (in Massachusetts).
497 grams of powder cocaine.

The package was found to contain

Although the evidence indicated that

Hernandez was the prime mover in arranging for the shipment, both
Wooldridge and Dunston encouraged his efforts. Thus, the 497 grams
of powder cocaine, destined for conversion into crack cocaine,
could fairly be attributed to Wooldridge for sentencing purposes.
See Cintrón-Echautegui, 604 F.3d at 5; USSG §1B1.3(a)(1)(B).
The fact that the package was intercepted before its
contents reached the defendants is of no moment.

The record makes

manifest that the defendants, in furtherance of the conspiracy,
sought the shipment of powder cocaine as a prelude to conversion
and would in all probability have converted it to crack cocaine if
given the chance.

drug traffickers have forged a well-defined pattern and practice
for their operations, a sentencing court need not turn a blind eye
to that pattern and practice.
Wooldridge tries to distance himself from this drug
weight, asseverating that no part of the August 31 shipment should
be attributed to him because his coconspirators had "cut[] [him]
out of the picture" by then.

But the evidence of exclusion is

meager, and the district court was not obliged to resolve this
issue in Wooldridge's favor.

Just as withdrawal from a conspiracy

requires more than an empty claim of disaffection, see United
States v. Piper, 298 F.3d 47, 53 (1st Cir. 2002) (explaining that,
in order to withdraw, a conspirator must take affirmative action
to disavow or defeat the conspiracy), so too does a claim of
exclusion.

There is simply no credible evidence that either

Wooldridge or his partners in crime took any such action here.

Hernandez's Sentence.

Hernandez's claim of sentencing error similarly embodies
a challenge to the district court's drug-quantity determination.

The court found him responsible for at least 2.8 kilograms of crack
cocaine.

Combined

calculations and a career offender enhancement, this drug quantity
resulted in a GSR of 292-365 months.

The district court imposed

a below-the-range sentence of 162 months.
The record is replete with circumstantial evidence that
Hernandez headed up the conspiracy.

He was involved in every

transaction that we have discussed: the events of June 26 (200

the probe, Hernandez can properly be held responsible for a minimum
of 2.2 kilograms of crack cocaine.
To boost that total to 2.8 kilograms, the district court
reasonably relied on two additional events.

First, the evidence

showed that, on July 29, Hernandez arranged the payment of $19,000
to

Cruz

for

powder

cocaine

supplied.

The

court

supportably concluded that this payment represented the purchase
of roughly 500 grams of powder cocaine.

See Sepulveda, 15 F.3d at

1201 (holding that when cash is likely dedicated to the purchase
of contraband, "a sentencing court may convert the cash into
equivalent amounts of narcotics" for sentencing purposes).

After

applying a one-to-one conversion ratio, this transaction yielded
500 grams of crack cocaine attributable to Hernandez.
The court reasonably added another 100 grams, based on
evidence that Hernandez was actively dealing crack cocaine between
January and June (when the wiretaps were instituted).

While this

finding represented an estimate, it was by all odds a conservative
estimate — especially since Hernandez pleaded guilty to conspiring
to deal crack as early as August of 2011.

the side of caution" (citation omitted)).
This gets the grease from the goose.

While we could

analyze these multiple transactions in more granular detail, doing
so would serve no useful purpose.

It suffices to say that the

record discloses ample evidence to ground a finding that Hernandez
was responsible for at least 2.8 kilograms of crack cocaine.

As

a result, we discern no clear error in the district court's drugquantity determination.
Hernandez has one last string to his bow. He takes issue
with the district court's designation of him as a career offender
under the sentencing guidelines.

§4B1.1(a)).

The government may carry this burden in divers ways,

such as by furnishing "a certified copy of the conviction or an

But anecdotal CORI descriptions, if objected to, are not

See id. at 154-55; cf. United States v. Brown, 510 F.3d

The district

court stayed the proceedings to give the government the opportunity
to make a more persuasive evidentiary proffer; but when the
government produced nothing more, the court overruled Hernandez's
objection and sentenced him as a career offender.
On appeal, Hernandez insists that the record before the
district court was insufficient to show the required predicate
offenses.

The government concedes this point and instead proffers

As a general

matter, we do not consider evidentiary materials that were not
proffered in the district court.

See United States v. Farrell,

672 F.3d 27, 30-31 (1st Cir. 2012); United States v. Kobrosky, 711
F.2d 449, 457 (1st Cir. 1983). Although we have occasionally taken
judicial notice of state court documents identified for the first
time on appeal, see, e.g., Farrell, 672 F.3d at 31; United States
v. Mercado, 412 F.3d 243, 247-48 (1st Cir. 2005), we cannot do so
here.

The proffered documents bear no hallmarks of authenticity

and, in all events, are subject to interpretation.

A career

offender designation can expose a defendant to a significantly
higher sentence, and it remains the district court's duty to ensure
that documents offered to prove the existence of predicate offenses
are "sufficiently reliable."

CONCLUSION
We need go no further. For the reasons elucidated above,

we affirm the judgment in appeal number 15-1812, thus affirming
Dunston's conviction and sentence. We likewise affirm the judgment
in appeal number 15-2000, thus affirming Wooldridge's conviction
and sentence.

With respect to appeal number 15-1999 (Hernandez),

we remand for further proceedings consistent with this opinion and
for the time being retain appellate jurisdiction over this appeal.

So ordered.
