Case No. 3:15-cv-226 JD

OPINION AND ORDER

Five plaintiffs seek damages from Johnson Controls for contamination that originated at 

Johnson Controls’ former manufacturing facility in Goshen, Indiana. As relevant to this motion, 

they argue that they were exposed to asbestos that became airborne when buildings at the site 

were demolished without proper abatement. Johnson Controls moves to exclude three expert 

opinions relative to that alleged asbestos exposure.

As a brief background, after ceasing operations at the site, Johnson Controls sold the site 

to a new owner. Around 2012, the new owner began demolishing some of the buildings without 

first abating all of the asbestos. Demolition activities took place over a couple years, during 

which debris piles remained in the open at the site. In early 2016, the Plaintiffs’ experts took 

samples of materials at the site and detected asbestos in dozens of samples. The Environmental 

Protection Agency then secured the site and implemented an expedited removal action. The 

Plaintiffs argue that by then, they had already been exposed to asbestos that became airborne at 

the site and blew to their properties. They do not attempt to identify the amount of asbestos to 

which they were exposed or argue that they have suffered any health effects, but they argue that 

the exposure itself supports their claims for nuisance, trespass, and infliction of emotional 

distress. [DE 388 p. 17 n.3, see also DE 399].

The Plaintiffs offer three expert reports in support of that theory. They first offer a joint 

report from two asbestos inspectors, Jeffrey Rechtin and Joseph Giddens, who opine that the 

buildings were torn down in violation of applicable regulations, that asbestos at the site became 

airborne, and that asbestos impacted each of the Plaintiffs’ properties. They next offer a report 

from an expert in photo analysis, Kristen Stout, who sets forth a narrative of activities at the site 

along with her observations of pictures taken at the site. Finally, they offer opinions from a 

meteorologist, Adam Stepanek, who analyzed the wind patterns in the area and opined that the 

wind blew in the direction of the Plaintiffs’ homes about a quarter of the relevant time.

Johnson Controls moves to exclude each of these opinions under Rule 702. It argues 

variously that the experts are not qualified, that their opinions are not reliable, or that the 

opinions would not be helpful to the jury. The Court addresses each expert in turn.

A. Standard of Review

Rule 702 governs the admission of testimony by expert witnesses. Under that rule, a 

witness “who is qualified as an expert by knowledge, skill, experience, training, or education” 

may offer an opinion if the following criteria are met:

(a) the expert’s scientific, technical, or other specialized knowledge will help 

the trier of fact to understand the evidence or to determine a fact in issue;

(b) the testimony is based on sufficient facts or data;

(c) the testimony is the product of reliable principles and methods; and

(d) the expert has reliably applied the principles and methods to the facts of the 

case.

Fed. R. Evid. 702.

A court has a gatekeeping role to ensure that expert testimony meets these criteria. 

Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993); C.W. ex rel. Wood v. Textron, Inc., 

807 F.3d 827, 834–35 (7th Cir. 2015). The proponent of the expert testimony bears the burden of 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 2 of 16

demonstrating that the testimony meets each of those elements. Varlen Corp. v. Liberty Mut. Ins. 

Co., 924 F.3d 456, 459 (7th Cir. 2019). However, a court does not assess “‘the ultimate 

correctness of the expert’s conclusions.’” Textron, 807 F.3d at 834 (quoting Schultz v. Akzo 

Nobel Paints, LLC, 721 F.3d 426, 431 (7th Cir. 2013)). Rather, a court must focus “solely on 

principles and methodology, not on the conclusions they generate.” Schultz, 721 F.3d at 432 

(quoting Daubert, 509 U.S. at 595). “So long as the principles and methodology reflect reliable 

scientific practice, ‘vigorous cross-examination, presentation of contrary evidence, and careful 

instruction on the burden of proof are the traditional and appropriate means of attacking shaky 

but admissible evidence.’” Id. (quoting Daubert, 509 U.S. at 596).

B. Jeffrey Rechtin and Joseph Giddens

The Plaintiffs first offer opinions from Jeffrey Rechtin and Joseph Giddens. Mr. Rechtin 

and Mr. Giddens each hold various licenses related to asbestos inspection, and they have 

experience in performing asbestos inspections and designing and supervising asbestos abatement

projects. They offer three opinions in their joint report. First, that the buildings at the former 

Johnson Controls site were torn down in violation of applicable regulations. Second, that 

asbestos fibers at the site became airborne during and after the demolition. And third, that 

“[e]ach of the five Plaintiffs were impacted by asbestos from the JCI Site when they were 

exposed to dust and debris contaminated with asbestos fibers that blew into their homes and onto 

their properties from the former JCI Site.” [DE 383-3]. Johnson Controls moves to exclude these 

opinions in their entirety.

Johnson Controls moves to exclude the first opinion—that the buildings’ demotion 

violated regulations—on the basis that it is an untimely opinion on liability. The Plaintiffs did 

not disclose these opinions during the discovery period, but only after the Court reopened 

discovery on the limited topics of exposure and damages. Johnson Controls thus argues that this 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 3 of 16
4

opinion is untimely. In response, the Plaintiffs argue that they do not offer this opinion as to 

liability, but only as to exposure. Thus limited, however, the opinion is not relevant. Mr. Rechtin 

and Mr. Giddens can discuss how activities at the site may have caused asbestos to become 

airborne—as they do in connection with their second and third opinions. But to add that, in 

addition to disturbing the asbestos, the activities violated applicable regulations (like the 

requirements to file a regulatory form, display signs, and have an inspector present) does not 

bear on whether the Plaintiffs were exposed or suffered damages.

This opinion does not trace noncompliance with regulations to the likelihood that 

asbestos was disturbed, either, as might make it relevant to exposure. It does just the opposite, 

stating that the site is covered with asbestos-containing debris, which proves that regulations

were violated. [DE 383-3 p. 10 (“The USEPA stated that ‘The demolition went forward with no 

(or grossly inadequate) abatement of asbestos. As a result, the site is covered with piles of 

asbestos-containing debris.’ These facts alone demonstrate that the buildings were torn down in 

violation of the applicable standards in Indiana asbestos regulations.”)]. Thus framed, this is just 

an untimely liability opinion, and the Plaintiffs do not argue it should be permitted in that event. 

The Court thus grants the motion to exclude Mr. Rechtin and Mr. Giddens’ Opinion 1.

In their second and third opinions, Mr. Rechtin and Mr. Giddens opine that asbestos at 

the site became airborne and that it reached each Plaintiff’s property. In formulating these 

opinions, they first visited the site and took samples from the demolition debris. Many of those 

samples detected asbestos. Mr. Rechtin and Mr. Giddens also reviewed documents reflecting the 

type and amount of asbestos that was in the buildings, as well as documents reflecting to what 

extent the asbestos was abated. They then reviewed documents and pictures of the site that 

reflected the demolition activities that occurred over the years. Based on their knowledge of

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 4 of 16
5

asbestos’ characteristics and the steps necessary to prevent it from becoming airborne, they 

evaluated to what extent those activities would cause asbestos that remained in the buildings to 

be disturbed and become airborne. They concluded that asbestos fibers had become airborne by 

at least February 2012, and that various activities at the site would have continued causing

asbestos to become airborne though February 2016.

To determine whether that asbestos would have reached the Plaintiffs’ properties, Mr. 

Rechtin and Mr. Giddens noted based on their training and experience that asbestos fibers can 

remain suspended in air for long periods of time, including two to three days in still air, or even

longer with air currents. They further noted that asbestos can be carried by the wind, and that 

because it is lighter than dust, dust is a good marker to show the minimum distance asbestos 

fibers would have traveled. They then considered testimony by the Plaintiffs and other neighbors 

about how the demolition activities created dust that blew onto their properties. Based on their 

earlier conclusion that asbestos fibers had become airborne at the site and were included in the 

debris, Mr. Rechtin and Mr. Giddens opined that those fibers would have traveled at least as far 

as the demolition dust and would have reached the Plaintiffs’ properties. Finally, Mr. Rechtin 

and Mr. Giddens considered the opinions from Dr. Stepanek, a meteorologist who opined that 

the wind blew towards the Plaintiffs’ homes on many days while asbestos was exposed at the 

site. Mr. Rechtin and Mr. Giddens believed that opinion corroborated the Plaintiffs’ statements 

about dust blowing towards their homes and supported their conclusion that asbestos fibers 

would have reached the Plaintiffs’ properties.

Johnson Controls moves to exclude these opinions on multiple grounds. It argues, for 

example, that Mr. Rechtin and Mr. Giddens are not qualified to offer these opinions because they 

have not conducted air modeling studies or reviewed scientific studies. It also argues that their 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 5 of 16
6

opinions are unreliable because they did not perform air sampling at the Plaintiffs’ properties, 

did not calculate the quantity of asbestos fibers to which the Plaintiffs were exposed, and did not 

employ a suitable methodology.

These arguments attempt to make this testimony more complicated than it needs to be. 

Not all expert testimony has to be offered by PhDs, entail a review of scientific literature, or 

employ complex modeling. See Fed. R. Evid. 702 (allowing expert testimony based on 

“scientific, technical, or other specialized knowledge”); Tuf Racing Prods., Inc. v. Am Suzuki 

Motor Corp., 223 F.3d 585, 591 (7th Cir. 2000) (“The Federal Rules of Evidence . . . do not 

require that expert witnesses be academics of PhDs, or that their testimony be ‘scientific’ . . . in 

character. Anyone with relevant expertise enabling him to offer responsible opinion testimony 

helpful to judge or jury may qualify as an expert witness.”). Mr. Rechtin and Mr. Giddens have 

the practical training and experience necessary to allow them to conduct asbestos inspections and 

to plan and oversee asbestos abatement. That training and experience produces specialized 

knowledge about how asbestos can become airborne, how long it can remain airborne, and how 

far it can travel. That knowledge is necessary to their jobs, as it allows them to take appropriate 

precautions for their own safety and to ensure that abatement is conducted in a manner that will 

prevent exposure to asbestos. They are not unqualified because they gained that knowledge in a 

practical instead of academic or scientific setting, and their opinions are not unreliable just 

because they did not perform advanced air modeling.

Nor is their opinion based solely on ipse dixit, as Johnson Controls contends. Mr. Rechtin 

and Mr. Giddens explain in their report how they conclude that asbestos became airborne at the 

site, as they discuss how buildings were demolished with asbestos still inside and without taking 

the precautions necessary to prevent asbestos from becoming airborne, and they explain how 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 6 of 16
7

those activities would have caused asbestos fibers to become airborne. They further explain how 

they conclude that asbestos reached the Plaintiffs’ properties. They note that asbestos is so light 

that it can remain in the air for days at a time. It is also lighter than dust, meaning that it will 

likely have travelled at least as far as any dust from the same place. As they explain by analogy, 

a river is likely to carry a pebble farther downstream than a rock, as a pebble is lighter and more 

easily carried by the current. And since the Plaintiffs observed dust being created at the site and 

settling on their properties, Mr. Rechtin and Mr. Giddens concluded that the lighter asbestos 

fibers would have travelled at least that far.

This analysis adequately grounds their opinions in their expertise and traces that expertise 

to their conclusions.1 Johnson Controls is entitled to point to the lack of air modeling or other 

lines of evidence that might have been used to confirm the presence of asbestos, and to ask the 

jury not to credit these opinions. But that is a matter of weight, not admissibility. Johnson 

Controls likewise argues that this analysis is so simple that expert testimony is not even helpful. 

The Court disagrees. Asbestos’ size and characteristics and its capacity to travel in the air are not 

matters of common knowledge, and these experts apply their knowledge of those topics to the 

facts of this case in a way that would help the jury understand whether asbestos would have 

reached the Plaintiffs’ properties.

Johnson Controls also argues that the Plaintiffs did not address the factors identified in 

Daubert as potentially bearing on the reliability of scientific testimony, such as whether the 

method has been peer reviewed or has a known rate of error. Daubert v. Merrell Dow Pharm., 

Inc., 509 U.S. 579, 593 (1993). Those factors were only “meant to be helpful, not definitive,” 

1 This analysis was absent from the report that was excluded at the class-certification stage, 

which also addressed a different question.

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 7 of 16
8

and they do not apply to all types of testimony. Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 

137, 150–51. Given the nature of these experts’ analysis and testimony, the Court does not find 

those factors useful here. See id. at 152 (“[T]he trial judge must have considerable leeway in 

deciding in a particular case how to go about determining whether particular expert testimony is 

reliable. That is to say, a trial court should consider the specific factors identified in Daubert

where they are reasonable measures of the reliability of expert testimony.”).

Johnson Controls further argues that Mr. Rechtin and Mr. Giddens failed to calculate the 

quantity of asbestos that became airborne or reached the Plaintiffs’ homes. That argument is not 

responsive to their opinions, though. They address only the fact of exposure, not the dose. The 

limited nature of that opinion may affect the scope of the Plaintiffs’ claims when it comes to 

liability or damages, but it does not render their opinion on that limited issue irrelevant or 

unreliable. The Court therefore denies the motion to exclude Opinions 2 and 3.

Finally, Johnson Controls objected to other aspects of the joint report that stray beyond 

these witnesses’ expertise. The report discusses, for example, the health impacts of asbestos, 

including the diseases it can cause and the latency periods to develop those diseases. [DE 383-3 

p. 6]. The Court agrees that Mr. Rechtin and Mr. Giddens lack the medical expertise to offer 

those opinions, and the Plaintiffs do not respond to this aspect of Johnson Controls’ motion. The 

Court thus excludes testimony on the medical impacts of asbestos. Johnson Controls also objects 

that the report includes extended recitations of documents and excerpts of deposition testimony, 

which were provided by counsel, not the experts. Many of those materials may be hearsay, but 

the experts’ opinions themselves are admissible, and the extent to which any otherwise 

inadmissible materials can be disclosed through these witnesses can be addressed at a later stage. 

See Fed. R. Evid. 703.

C. Kristen Stout

The Plaintiffs next offer an expert report from Kristen Stout. Ms. Stout has experience in 

aerial photographic analysis, which she has applied in assessing hazardous waste sites for the 

Environmental Protection Agency. Though she has experience in photogrammetry—the use of 

aerial photographs to create maps and generate measurements—her work in this case did not 

draw on that expertise. Rather, she applied what she called photo analysis, which entailed 

reviewing pictures and documents to create a timeline of activities at the site. Her report offers a 

factual narrative of the demolition activities at the site, with recitations of documentary evidence 

and her observations from various pictures. In her words, Ms. Stout “tells the story” of what 

activities took place at the site. [DE 383-16 p. 57; see also id. p. 40 (“[M]y role was, primarily, 

to document the demolition activities and how the debris was handled and moved around the 

site.”)].

In moving to exclude this testimony, Johnson Controls primarily contends that the 

Plaintiffs are simply offering their own factual narrative under the guise of expert testimony. It 

argues that Ms. Stout did not bring an expertise to bear, but recited documents and other peoples’ 

opinions and offered observations of pictures that a jury would be equally capable of observing 

for itself. Rule 702 allows expert testimony if “the expert’s scientific, technical, or other 

specialized knowledge will help the trier of fact to understand the evidence or to determine a fact 

in issue.” Fed. R. Evid. 702(a). This does not merely mean that the expert’s testimony must be 

relevant; expert witnesses must bring their expertise to bear in such a way that their expertise

helps relate the evidence to the jury in a way that will assist the jury’s understanding of the 

evidence. United States v. Benson, 941 F.2d 598, 604 (7th Cir. 1991), amended on unrelated 

grounds, 957 F.2d 301 (7th Cir. 1992) (“An expert’s opinion is helpful only to the extent the 

expert draws on some special skill, knowledge, or experience to formulate that opinion; the 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 9 of 16
10

opinion must be an expert opinion (that is, an opinion informed by the witness’ expertise) rather 

than simply an opinion broached by a purported expert.”); see also Sullivan v. Alcatel-Lucent 

USA Inc., No. 12 C 07528, 2014 WL 3558690, at *5 (N.D. Ill. July 17, 2014); In re Rezulin 

Prods. Liability Lit., 309 F. Supp. 2d 531, 540 (S.D.N.Y. 2004).

Thus, “an expert witness may not simply summarize the out-of-court statements of others 

as his testimony.” United States v. Brownlee, 744 F.3d 479, 482 (7th Cir. 2014) (internal 

quotation omitted). Likewise, “An expert ‘cannot be presented to the jury solely for the purpose 

of constructing a factual narrative based upon record evidence.’” Newman ex rel. Newman v. 

McNeil Consumer Healthcare, No. 10 C 1541, 2013 WL 9936293, at *6 (N.D. Ill. Mar. 29, 

2013) (quoting In re Fosamax Prods. Liab. Litig., 645 F. Supp. 2d 164, 192 (S.D.N.Y. 2009)). 

“Acting simply as a narrator of the facts does not convey opinions based on an expert’s 

knowledge and expertise; nor is such a narration traceable to a reliable methodology. Mere 

narration thus fails to fulfill Daubert’s most basic requirements.” S.E.C. v. ITT Educ. Servs., Inc., 

311 F. Supp. 3d 977, 987 (S.D. Ind. 2018).

The Court agrees with Johnson Controls’ characterization of Ms. Stout’s report as 

offering only a factual narrative, which is not the realm of expert testimony. The Plaintiffs 

disagree, arguing that the narrative provides the factual underpinning for her opinions. Yet, they 

have great difficulty articulating what those opinions are or what expert gloss she offered beyond 

reciting a narrative or offering observations that would be apparent to a lay person. They even 

say that her role was to review pictures and documents and “develop a timeline of site activities.” 

[DE 388 p. 26]. As just noted, “constructing a factual narrative based upon record evidence” is 

not a role for expert testimony—that’s a lawyers job through the presentation of evidence and 

through opening statements and closing arguments. Newman, 2013 WL 9936293, at *6; see also 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 10 of 16

Empire Med. Review Servs., Inc. v. CompuClaim, Inc., No. 13-cv-1384, 2018 WL 5823660, at *3 

(E.D. Wis. Mar. 16, 2018). Ms. Stout likewise had difficulty identifying what expert opinions 

she had to offer, as she testified that her opinion was “actually the narrative” in her report. [DE 

383-16 p. 36]. Of course, it is possible that an expert could draw on her experience to provide 

insight that would be helpful in understanding the course of events, see Newman, 2013 WL 

9936293, at *6, but the Plaintiffs have not shown how Ms. Stout did so here.

An example helps illustrate the point. The following excerpt is representative of much of 

Ms. Stout’s report:

In February the plaintiffs’ environmental consultant, Keramida, Inc., collected 

debris samples from the debris piles which tested positive for asbestos. 

(KERA030776) This triggered an EPA Emergency Response Action. EPA’s 

contractors were dispatched to the Site to conduct an inspection and collect 

additional samples. The inspection and sampling confirmed the presen[ce] of ACM 

[Asbestos Containing Material] on Site, including friable asbestos. The EPA 

determined that, “the site is covered with piles of asbestos-containing debris. Some 

of the asbestos is on the surface and can (and has) become airborne.” (EPA Action 

Memorandum, 2016) The debris piles were covered with plastic tarps to prevent 

further releases of asbestos dust into the air. A security fence was installed along 

East Monroe Street and the alleyway to restrict access to the Site, and warning signs 

were posted. See Figures 10-1, 10-2. (https://response.epa.gov/site/site_profile.

aspx?site_id=11449)

In August 2016, EPA initiated a Time-Critical Removal Action to remove 

approximately 7,000 tons of readily identifiable ACM wastes from debris piles and 

pits (sub-grade structures) on Site. The Removal Action employed standard safety 

practices for handling asbestos wastes. In Figure 10-3 a worker in a hazmat suit and 

wearing a respirator is applying water to the debris pile. The debris piles were kept 

wet to prevent asbestos dust from becoming airborne while handling and loading 

the debris into trucks for offsite disposal. Note the plastic sheeting covering the 

transport truck in Figure 10-4. Figures 10-5 through 10.8 show several of the subgrade structures after EPA had removed the debris.

[DE 383-4 p. 13–14].

The first paragraph does not include any photographic analysis—the sole area of 

expertise the Plaintiffs invoke. [DE 388 p. 27]. It offers only a passing citation to two pictures 

after noting things that are readily apparent from the pictures themselves: that a fence was 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 11 of 16
12

erected and a warning sign was posted. The rest of discussion in this paragraph merely recites 

documents without bringing any expertise to bear. The second paragraph references several 

pictures, but again offers no expertise. It notes, for example, that a worker in Figure 10-3 is 

wearing a hazmat suit and respirator, but that is apparent to any lay juror from observing the 

picture.

The only aspect of that discussion drawing on expertise—the statement that debris piles 

were kept wet to prevent asbestos from becoming airborne—is not a product of Ms. Stout’s 

expertise in photo analysis. Rather, that statement would require expertise in the proper handling 

and abatement of asbestos. That is the subject of Mr. Rechtin and Mr. Giddens’ report, as already 

discussed, but Ms. Stout is not an expert in that subject. She testified that she has read standards 

on handling asbestos and previously worked on a project involving asbestos. But having read 

standards on handling asbestos does not qualify someone as an expert on that topic, see Bagher 

v. Auto-Owners Ins. Co., No. 1:12-cv-980, 2014 WL 1224453, at *5 (D. Colo. Mar. 25, 2014), 

and Ms. Stout’s role in the previous project was reviewing pictures to determine distances and 

directions and create demonstrative exhibits. Again, Mr. Rechtin and Mr. Giddens can testify on 

the proper handling of asbestos, but Ms. Stout is not an expert on that topic, and her narrative of 

the other evidence is not helpful to the jury.

In other portions of her report, Ms. Stout notes that pictures taken at different times show 

debris piles in different places, indicating the piles had been moved, or describes how pictures 

reflect that different buildings were torn down over time. Those may be accurate observations of 

those pictures, but they do not require expert testimony for a jury to understand. See Sullivan, 

2014 WL 3558690, at *6 (“Expert testimony does not assist the trier of fact when the jury is able 

to evaluate the same evidence and is capable of drawing its own conclusions without the 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 12 of 16
13

introduction of a proffered expert’s testimony.” (quotation and alteration omitted)); Rezulin, 309 

F. Supp. 2d at 551 (“[The expert’s testimony] is merely a narrative of the case which a juror is 

equally capable of constructing. In [the expert’s] own words, the purpose of this testimony is 

simply to ‘provide an historical commentary of what happened’ . . . . Such material, to the extent 

it is admissible, is properly presented through percipient witnesses and documentary evidence.”).

Other portions of the report recite at length from other documents or other people’s statements or 

opinions without applying any expertise in photo analysis.

As a contrary example, the Plaintiffs point to a statement in Ms. Stout’s report where she 

notes that a picture reflects “heterogeneity of the materials in the debris piles,” suggesting the 

materials had been smashed and mixed together. A jury does not need expert testimony to look at 

the picture and see that the materials in the debris appear to have been broken up and mixed 

together, though. The Plaintiffs have not articulated how Ms. Stout drew on her expertise in 

photo analysis to appreciate anything more than would be apparent to a lay juror, or how she 

applied a reliable methodology in offering that observation. Again, Mr. Rechtin and Mr. Giddens 

may be able to address what demolition activities would produce the conditions shown in those 

pictures and whether those activities would cause asbestos to become airborne, but that is not 

within Ms. Stout’s expertise in photo analysis.

That is not a slight to Ms. Stout or the value of her work. Her assimilation of information 

into a narrative may have been quite useful to the Plaintiffs’ counsel in investigating their case

(which she noted was the purpose for which she was originally retained). The problem is that 

counsel offered her testimony in a capacity that is not a proper subject of expert testimony. 

Reviewing evidence and drafting a timeline does not qualify a person to testify as an expert 

witness on the course of events any more than a lawyer becomes qualified to testify as an expert 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 13 of 16
14

by drafting a statement of facts. Because the Plaintiffs have not shown that this report goes 

beyond presenting a narrative or that it draws on expertise that would assist the jury, the Court 

excludes Ms. Stout’s expert testimony.

D. Adam Stepanek

Finally, Johnson Controls moves to exclude the opinions by Adam Stepanek, a 

meteorologist. Dr. Stepanek was asked to opine on how often the wind blew in the direction of 

the Plaintiffs’ homes from the Johnson Controls site. He examined the wind observations from a 

nearby airport, which he found to be a suitable proxy for the conditions in the neighborhood. He 

then averaged the observed wind speeds and directions for each day. He concluded that over the 

relevant period, the wind blew in the direction of at least one of the Plaintiffs’ homes on 415 

days.

First, Johnson Controls moves to exclude this testimony on the basis that expert 

testimony on this topic would not be helpful. Fed. R. Evid. 702(a). The Court disagrees. Dr. 

Stepanek’s expertise is helpful in connecting observations from a nearby observation site 

(Goshen Municipal Airport) to the conditions in the Plaintiffs’ neighborhood, and in interpreting 

and synthesizing those observations to determine average wind directions during the relevant 

period. Johnson Controls argues that this wind-direction testimony is unhelpful because it fails to 

establish that the Plaintiffs were actually exposed to asbestos. That argument misconceives the 

role of Dr. Stepanek’s testimony, though. Dr. Stepanek’s testimony is a building-block upon 

which Mr. Rechtin and Mr. Giddens rely in reaching their opinion that asbestos reached the 

Plaintiffs’ properties. Dr. Stepanek opines on the wind direction, and Mr. Rechtin and Mr. 

Giddens use their expertise on the characteristics of asbestos to opine that wind traveling in that

direction would have carried asbestos to the Plaintiffs’ properties. Dr. Stepanek’s opinion is 

USDC IN/ND case 3:15-cv-00226-JD document 404 filed 08/21/20 page 14 of 16
15

narrow, but it is still helpful for that narrow purpose, so that is not a ground for excluding his 

testimony.

The rest of Johnson Controls’ arguments appear directed only to statements Dr. Stepanek

made at his deposition, not opinions in his report. Dr. Stepanek opined in his report that “there 

are days in which the wind direction would have supported the motion of airborne particles from 

the JCI site toward each of the four specified households.” [DE 383-5]. As just noted, his report 

does not address or offer opinions on asbestos. Johnson Controls argues that he went beyond that 

opinion during his deposition, though, and opined that the wind would have carried asbestos in 

particular. [E.g., DE 383-18 p. 132 (“In the event that there were airborne particles to potentially 

include asbestos in the air, on these days, the wind direction would have moved said particles 

from the JCI site toward one or more of those homes.” (emphasis added))].

In context, however, it is apparent that Dr. Stepanek is not offering any opinion specific 

to asbestos, including whether asbestos was actually in the air, whether its characteristics would

cause it to remain in the air, or whether it would have traveled all the way from the site to any 

Plaintiffs’ property. He was merely noting that the wind was blowing in a given direction, and 

that any particles suspended in the air and being blown by the wind would have been blown in 

that direction. There’s no need to further complicate this opinion; Dr. Stepanek is a meteorologist 

who opines on wind direction and speed. The Plaintiffs confirm in their response that they only 

offer Dr. Stepanek’s testimony for that narrow purpose, and that they rely on the other experts to 

connect that testimony to asbestos. Dr. Stepanek’s opinions on that narrow topic satisfy Rule 

702, so the Court denies the motion to exclude Dr. Stepanek’s testimony.

E. Conclusion

Johnson Controls’ motion to exclude the expert opinions on asbestos exposure is granted 

in part and denied in part. [DE 383]. As to Mr. Rechtin and Mr. Giddens, the Court excludes
