CASE NO. 4:15-CV-0130
MEMORANDUM AND ORDER
Pending before the Court is Defendant Trippe Manufacturing Company’s
(“Trippe”) Motion to Strike and Exclude the Testimony of Plaintiff’s Expert
Witnesses (“Motion”) [Doc. # 36]. Plaintiff Harris CapRock Communications,
Inc. (“Harris”) has filed a Response [Doc. # 41]. Trippe has neither filed a Reply
nor requested additional time to do so. Having reviewed the record and relevant
legal authorities, the Court denies the Motion.
This lawsuit arises from a fire that ignited in the early morning hours of
Sunday, March 3, 2013, at Harris’s global headquarters, located in Houston,
The record reflects the following.
The fire was contained to
“Teleport/TelOps Building C,” a freestanding, detached modular steel building
located behind the main facility and used for operations maintenance and

equipment storage.2 The Houston Fire Department responded soon after receiving
notice of the fire, extinguishing it within hours.3
Observing that the “[f]ire
appeared to have started in the middle of the room,” the Fire Department, after
learning Building C had been vacant for the two days prior to the fire, suspected
arson and called in the Houston Arson Bureau.4
Based on its investigation of the scene and interviews with firefighters and
Harris employees who worked in the building, the arson investigators concluded
the fire originated on or near two plastic carts, whose fire-damaged remains were
in the center of the room, when equipment on the carts malfunctioned.5 By the
time the arson investigators arrived on the scene the carts’ contents had fallen to
the floor.6 The arson investigators photographed the area as they observed it
before engaging in what one of Harris’s experts refers to as “minimal
reconstruction” of the scene, including attempting to place several of the items
back onto the carts.7 The Houston Arson Bureau classified the fire an accident.8
Harris retained fire investigator Joseph Ellington, who was the first person to

survey Building C after it was released by the Houston Fire Department.9 On
March 5 and 6, 2013, Ellington inspected Building C, taking more than three
hundred photographs of the scene over the course of the two days.10 Ellington’s
goal in conducting the initial inspection was to document and preserve the scene
and physical evidence.11 Relying on information provided by Kevin S. McElroy,
who, at the time of the incident, was a Teleport Engineer responsible for the
equipment in the building, Ellington attempted to identify where each of the fallen
items would have been located on the carts prior to the fire.12
Ellington concluded that the fire originated on the northern-most of two carts
(the “north cart”). He “bagged and tagged” as evidence items that were on both
the north and south carts, among other items.13 Ellington apparently positioned
those items where the north and south carts typically stood.14
Approximately a week later, on March 11, 2013, Ellington and Kevin R.
Davis, an engineer and fire investigator retained by Harris’s insurer, conducted a

joint examination of Building C at Harris’s request.15 Davis ultimately concluded
that the source of the fire was a Trippe Uninterruptible Power Supply system
(“UPS”), which was located at the time of the fire on the bottom shelf of the north
cart.16 Ellington accordingly notified Trippe of the fire, in accordance with fire
investigation protocol.17 On April 17, 2013, Ellington and Davis conducted a joint
examination of the scene with, among others, Trippe’s retained fire origin and
Harris filed suit against Trippe in the 164th Judicial District Court of Harris,
County, Texas, asserting claims of strict products liability and breach of implied
warranties.19 Trippe timely removed the case to federal court [Doc. # 1]. Trippe
now moves to exclude the expert opinions proffered by three of Harris’s
designated experts. Harris has responded in opposition. The Motion is ripe for

Witnesses who are qualified by “knowledge, skill, experience, training or
education” may present opinion testimony to the jury. FED. R. EVID. 702; see, e.g.,

v. Gayden, 571 F.3d 442, 452 (5th Cir. 2009). To be admissible, an expert’s
proffered testimony must be both relevant and reliable. Daubert v. Merrell Dow

Sys., Inc., 822 F.3d 194, 199 (5th Cir. 2016).
The expert testimony must be relevant and the expert’s proposed opinion
must be one that would assist the trier of fact to understand or decide a fact in
issue. See Weiser-Brown Operating Co. v. St. Paul Surplus Lines Ins. Co., 801
F.3d 512, 529 (5th Cir. 2015); Bocanegra v. Vicar Servs., Inc., 320 F.3d 581, 584
(5th Cir. 2003) (citing Daubert, 509 U.S. at 591-92). “A party seeking to introduce
expert testimony must show (1) the testimony is based upon sufficient facts or
data, (2) the testimony is the product of reliable principles and methods, and (3) the
witness has applied the principles and methods reliably to the facts of the case.”

227 (5th Cir. 2007)); see also Carlson, 822 F.3d at 199.
“Reliability” requires that the proponent of the expert testimony must
present some objective, independent validation of the expert’s methodology. See
Brown v. Illinois Cent. R. Co., 705 F.3d 531, 536 (5th Cir. 2013). The objective of
the Court’s gatekeeper role is to ensure that an expert “employs in the courtroom
the same level of intellectual rigor that characterizes the practice of an expert in the
relevant field.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 152 (1999); Hodges
v. Mack Trucks Inc., 474 F.3d 188, 194 (5th Cir. 2006).
The Court’s gatekeeping role is no substitute, however, for the adversarial

Ellington, the regional fire division manager of Rimkus Consulting Group,
is a fire investigator certified by the National Association of Fire Investigators and
the International Association of Arson Investigators with over thirty years’
experience in advanced technical investigations generally. Ellington has expertise
in investigating fires of unknown or disputed origin, and in causes and
responsibility of fires and explosions.20 Based on Ellington’s detailed examination
of the scene of the fire, including observable fire damage and burn patterns in the
building and its contents, he opines that the fire originated on the lower level of the
north cart.21 In reliance upon his investigation and the opinion of Kevin Davis,
another Harris expert, Ellington adopts the conclusion that the Trippe UPS caused
the fire.22 Ellington ruled out other potential origins of the fire.23

Trippe seeks to exclude Ellington’s testimony on two grounds. First, Trippe
contends that Ellington’s opinion that the north cart was the origin of the fire is
purely speculative. Second, Trippe argues that Ellington’s opinions are unreliable
because he failed to comply with standard fire investigation protocol when he
“bagged and tagged” evidence selectively and without cause.
Ellington’s expert opinions are based upon his multiple examinations of the
fire scene, evidence secured from Building C, the reports of the Houston Fire
Department and Houston Arson Bureau, and Davis’s reports. They are sufficiently
reliable as required by Daubert, Kumho and Federal Rule of Evidence 702.
Ellington concluded that the fire originated on the north cart based upon the burn
patterns in the building and on various items within it.24 To the extent Trippe urges
the Court to strike Ellington’s testimony because Ellington personally fails
specifically to identify the Trippe UPS as the cause of fire, the argument is
unavailing. Ellington may testify to his opinion on the point of origin of the fire
and rely on other reliable expert testimony in concluding the precise cause at that
origin. See FED. R. EVID. 702 Advisory Committee’s note to 2000 amendment
(“The term ‘data’ is intended to encompass the reliable opinions of other experts.”)
It is an approved practice in fire investigations for a fire investigator to consult
persons with specialized knowledge or experience that the investigator lacks.25
Trippe also contends that Ellington’s testimony is unreliable because of the
way he identified items to save as evidence. The 2011 edition of the National Fire

at 6, at ECF 9.
See NATIONAL FIRE PROTECTION ASSOCIATION, GUIDE FOR FIRE AND EXPLOSION
INVESTIGATIONS § 15.5.1 (2014 ed.) (“NFPA 921-2014”), Exh. 1 to Harris
Response [Doc. # 41-1], at ECF 16.
Protection Association Guide for Fire and Explosion Investigations (“NFPA 9212011)26 specifically contemplates the alteration and movement of evidence,
including collecting and removing physical evidence in order to test items or to
ensure their preservation.27
NFPA 921-2011 affords discretion to the fire
investigator in determining what physical evidence to collect.28 Further, during the
April 17, 2013 joint examination of the scene, Trippe’s experts had the opportunity
to—and in fact did—identify as additional evidence items Ellington had not
originally “bagged and tagged.”29
Trippe’s arguments challenging Ellington’s
decisions regarding which evidence to collect and the significance to be drawn
from his examinations go to the weight rather than to the admissibility of his
opinions. Trippe may cross-examine Ellington on these matters, as needed to test
his conclusions and their bases.
Kevin R. Davis
Kevin R. Davis is a certified fire investigator and licensed engineer.30 He
holds a BS in Electrical Engineering, and is a member of the National Association
of Fire Investigators and the Institute of Electrical and Electronic Engineers,
Trippe cites the 2014 edition of the NFPA 921 in challenging Ellington’s expert
opinion. As Harris correctly points out, that edition had not yet been released at
the time Ellington examined the fire scene. Accordingly, the Court considers both
NFPA 921-2014 and its predecessor, the 2011 edition.
See §§ 18.104.22.168 & 16.2.2 of NFPA 921-2011, Exh. 2 to Harris Response [Doc.
# 41-2], at ECF 12-13.

among other organizations.31 He is presently employed as a professional engineer
by Goodson Engineering.32
Davis provides various opinions. Trippe seeks to exclude Davis’s
conclusions because they allegedly are not supported by “any” Daubert reliability
factors. More specifically, Trippe argues that Davis’s opinions are unreliable
because they are based on evidence that was “cherry-picked” by Ellington. Trippe
also contends that Davis’s opinions on the source of the ignition and the “first fuel”
are not reliable. Harris has provided persuasive arguments in response.
First, it is noted that there is ample support in the record for the methodology
Davis adopted to analyze the evidence Ellington and others analyzed. See Section
II.B, supra. Trippe’s contention that the evidence was “cherry-picked” evidence
ignores Davis’s and Ellington’s cited references and reliance on techniques
approved in NFPA 921, practices in the fire investigation industry, and Ellington’s
personal close examinations of the fire scene and the condition of many items
found there. See, e.g., Section II.B supra. Further, Davis arrived at his opinions
based on, inter alia, his own detailed examinations of the fire scene, tests he
conducted on the evidence Ellington “bagged and tagged,” and scrutiny of other
Trippe UPS exemplars.
As noted, Trippe had the opportunity to add to the
evidence items that Ellington had not chosen, and did so. This challenge is without
Davis’s opinions that Trippe particularly challenges are that the origin of the
fire was wires at the front of the Trippe UPS; that the source of ignition of the fire
was an internal electrical failure of the Trippe UPS; and that the first fuel ignited
was debris that collected in the UPS unit, which then set aflame the plastic bezel
on the front of the Trippe UPS.33 For reasons summarized below, the Court denies
Trippe’s Motion regarding Davis’s opinions because the challenges are essentially
attacks on the weight his conclusions should be given, matters for the fact finder.
Trippe argues that Davis’s opinions regarding the source of ignition at the
UPS and the “first fuel” that started the fire are speculative and unreliable because,
for instance, Davis does not know that there was debris in the UPS unit at issue and
did not test the flammability of the north cart. These assertions technically are
true. However, the UPS was essentially destroyed in the fire and it was impossible
to ascertain whether dust or debris was in pertinent parts of the UPS. Davis,
however, found debris or dust in one or more exemplar UPS units. Second,
Harris’s third expert, Thomas W. Eagar, Sc.D., supplies considerable support for
Davis’s opinions.34 Further, the flammability rating of the north cart is a matter
ascertainable from independent sources by experts, including those Trippe
retained.35 The approaches Davis has taken to theorize the conditions of the UPS
at the time of the fire, and to eliminate other potential causes of ignition and first
fuel of the fire, has support in the specialized arena of fire investigation.36

Trippe also contends that Davis’s “creep” theory—that the insulation
covering battery wires inside the Trippe UPS gradually deteriorated from the
wires’ constant contact with fixed portions of the UPS, which created detrimental
arcing—is not supported sufficiently in the scientific literature. First, Trippe does
not cite to authority rejecting the creep theory completely, but instead
acknowledges that the NFPA delineates “very narrow circumstances” in which
creep may cause a fire.37 Further, Eagar provides some support for “creep” as an
accepted scientific concept in his deposition and affidavit.38 As noted, Eagar’s
report also supports Davis’s conclusions regarding the ignition and sequence of the
fire.39 Further, significantly, Davis considered and eliminated various potential
alternate causes for the fire, and has provided reasons for his conclusions that
demonstrate he generally followed procedures and engaged in analysis that appear
to be consistent with accepted protocol in fire investigations as suggested by NFPA
921.40 The Court is persuaded that Davis has developed his theories using the
same rigor as accepted in the fire investigation industry. See Kumho Tire, 526 U.S.
Trippe also argues that certain of Davis’s views are not endorsed by Harris’s
third expert, Eagar. Any such disagreements or purported weaknesses in Davis’s

2011) (“[a]s a general rule, questions relating to the bases and sources of an

admissibility and should be left for the jury’s consideration.”) (quoting United
States v. 14.38 Acres of Land, 80 F.3d 1074, 1077 (5th Cir. 1996)).
Therefore, Davis’s opinions are sufficiently grounded in methodology,
technical theory, specialized knowledge, and logic to satisfy the Court’s Daubert
gatekeeping responsibility. The Court will allow Davis’s expert testimony and
Trippe will be free to test his conclusions and methodology through crossexamination, to enable the jury to decide whether these opinions are credible and
Thomas W. Eagar
Harris retained Thomas W. Eagar, Sc.D., to respond, as a rebuttal expert, to
Trippe’s expert disclosures. Eagar is a professor of Materials Engineering and
Engineering Systems at Massachusetts Institute of Technology (“MIT”), and has
been on its faculty since 1976.41 Eagar is a member of the American Society of
Mechanical Engineers and the National Academy of Engineering, among other
organizations, and is the author of numerous publications related to metals and the
effect of heat on metals.42 He has conducted analyses on more than one hundred
metallurgical and forensic engineering projects and has qualified as an expert in

state and federal courts and international arbitrations for over three decades.43
Eagar reviewed Davis’s report, dated November 11, 2015. On April 11,
2016, Eagar inspected the items Ellington had segregated as evidence from the
north and south carts at the time of the fire, and that Davis tested.44 Eagar also
reviewed Trippe’s disclosure of expert testimony and the written reports and
deposition testimony of Trippe’s retained experts.45 Based on the foregoing, as
well as his experience and education in materials engineering, heat flow, physics,
and failure analysis, Eagar formed several rebuttal opinions in response to Trippe’s
Trippe’s objections to Eagar’s opinions, like those made with respect to
Ellington and Davis, actually are challenges to the weight of Eagar’s testimony.
Trippe argues, for example, that Eagar’s opinion that the battery packs in the
Trippe UPS could leak electric current is speculative and unreliable because Eagar
did not perform any tests to determine whether his theory was possible. Trippe
makes a similar argument with respect to Eagar’s theory that heat produced by the
alleged leak ignited lint in the UPS unit that, in turn, ignited the plastic bezel on the
front of the Trippe UPS: Trippe asserts that the opinion is speculative because
Eagar failed to test the flammability of the plastic on the front of the Tripp UPS.
Trippe also argues that Eagar’s opinions regarding compromised insulation of
battery wires, offered in addition to the battery leakage theory, are speculative and

unreliable.47 The Court has carefully reviewed Eagar’s report, deposition, and
affidavit, and concludes that his testimony is adequately tethered to accepted
technical knowledge and methodology. Eagar’s experience, logic, and specialized
skills in various pertinent subject areas satisfy applicable legal standards. He
explains in detail the bases of his conclusions. Trippe’s disagreements go to the
weight of his testimony and are matters that may be explored through crossexamination before a jury.

Some of these criticisms, such as the lack of flammability tests, may be unfounded
in light of Trippe’s own expert’s deposition testimony.
