                            /                                            
                            ORDER                                        
    This cause is before the Court on Defendants’ Revised Daubert Motion to 
Exclude  Anonymous  Opinions  in  the  Fire  Rescue  Report  and  Fire  Chief 
Wienckowski’s  Alleged  Opinions.  (Doc.  95  (the  “Motion”)).  The  Plaintiff 
submitted a response in opposition. (Doc. 101). Upon consideration, the Motion is 
denied because the alleged opinions do not constitute expert or lay witness opinion 
testimony. For the sake of clarity, the Court also addresses in this Order lay witness 
opinions that are admissible.                                             
I.   BACKGROUND                                                           
    The Defendants seek to exclude findings, which they describe as expert 
opinions, contained in the Orange County Fire Rescue Report (Doc. 95-1 (the 
“Report”)),  that  the  fire  damaging  the  Plaintiff’s  home  was  caused  by  the 
Thermacell  Patio  Shield.  (Doc.  95,  pp.  1–4).  Lieutenant  Lizbeth  Desio  (“LT 
Desio”) states in the Report that:                                        
         Per home owner [sic], fire started in the second[-]floor patio  
         from a ‘Thermocell Patio Shield Mosquito Repellent’ device.     
         She [Flynn] stated that she followed manufacturer directions    
         and placed the device on a patio table with no flammable        
         objects in its immediate vicinity, ignited the device and when  
         she returned to the device several minutes later, the device    
         had caught on fire.                                             
(Id. at pp. 3–4 (quoting Doc. 95-1, p. 4)).                               
    The Defendants also seek to exclude findings attributed to Fire Chief Garrett 
Wienckowski  (“Chief  Wienckowski”)  in  Plaintiff’s  Amended  Answers  to 
Interrogatories that “the Thermacell Patio Shield product was the origin and cause 
of the January 21, 2021, fire which damaged the Flynn’s home in Orlando, Florida.” 
(Id. at p. 3 (quoting 95-2, pp. 2–3)).1 The Defendants claim that LT Desio and Chief 
Wienckowski’s findings, or opinions, that the fire originated with the Patio Shield 
must be excluded, because they are based on the incorrect impression that the 
Plaintiff observed the Patio Shield to have caused the fire, and otherwise fail to 
satisfy the Daubert standard for admissibility. (Id. at pp. 5–7).         
    The Plaintiff responds that the Report is admissible under Federal Rule of 
Evidence 803(b) as a business record. (Doc. 101, p. 6). The Plaintiff also contends 
that Chief Wienckowski’s opinions regarding the cause of the fire are admissible 
based on his observations at the scene and information learned from witnesses. 
(Id.  at  pp.  7–8).  The  Plaintiff  argues  that  Chief  Wienckowski  should  not  be 


1   As discussed below, Chief Wienckowski did not identify the cause of the fire.  
prevented from testifying to the following opinions: (1) the damage is consistent 
with the fire starting on the second-floor balcony; (2) no evidence suggests an 
electrical  fire;  (3)  the  fire  was  accidental;  and  (4)  information  learned  from 

witnesses (that the Patio Shield caused the fire). (Id. at p. 8).         
II.  LEGAL STANDARDS                                                      
    The Daubert standard is properly summarized in the Defendants’ Motion. 
Defendants note that Federal Rule of Evidence 702 permits “[a] witness who is 
qualified as an expert by knowledge, skill, experience, training, or education” to 

testify in the form of an opinion. Rule 702 imposes an obligation on district courts 
to act as gatekeepers “to ensure that speculative, unreliable expert testimony does 
not  reach  the  jury”  under  the  mantle  of  reliability  that  accompanies  “expert 
testimony.” McCorvey v. Baxter Healthcare Corp., 298 F.3d 1253, 1256 (11th Cir. 
2002); see Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 589 (1993). This 
gatekeeping role applies “not only to testimony based on ‘scientific’ knowledge, but 

also to testimony based on ‘technical’ and ‘otherwise specialized’ knowledge.” 
Kumho Tire Co. v. Carmichael, 526 U.S. 137, 141, 147–48 (1999).           
    The party offering an expert opinion has the burden of establishing three 
criteria  by  a  preponderance  of  the  evidence:  qualification,  reliability,  and 
helpfulness. See McClain v. Metabolife Int’l, Inc., 401 F.3d 1233, 1238 (11th Cir. 

2005); Rink v. Cheminova, Inc., 400 F.3d 1286, 1292 (11th Cir. 2005). That said, 
“neither Daubert nor its progeny preclude experience-based testimony.” Butler v. 
First Acceptance Ins. Co., 652 F. Supp. 2d 1264, 1272 (N.D. Ga. Aug. 17, 2009) 
(quoting  Kumho  Tire,  526  U.S.  at  151).  “When  an  expert  relies  primarily  on 
experience, the witness must explain how that experience leads to the conclusion 
reached, why that experience is a sufficient basis for the opinion, and how that 

experience is reliably applied to the facts.” Id. (quoting U.S. v. Frazier, 387 F.3d 
1244, 1261 (11th Cir. 2004)).                                             
    While  the  parties  focus  on  the  standard  announced  in  Daubert,  they 
overlook the fact that “[Federal] Rule [of Evidence] 701 does not prohibit lay 
witnesses from testifying based on particularized knowledge gained from their own 

personal experience. United States v. Hill, 643 F.3d 807, 841 (11th Cir. 2011). Thus, 
a  lay  witness  may  offer  opinions  that  are  “rationally  based  on  the  witness’s 
perception”;  “helpful  to  clearly  understanding  the  witness’s  testimony  or  to 
determining a fact in issue”; and “not based on scientific, technical, or other 
specialized knowledge within the scope of Rule 702.” United States v. Jeri, 869 
F.3d 1247, 1265 (11th Cir. 2017). For example, a law enforcement officer who read 

and listened to thousands of wiretap conversations may testify about the meanings 
of code words that he learned during the investigation. United States v. Jayyousi, 
657 F.3d 1085, 1103–04 (11th Cir. 2011); see also Eberhart v. Novartis Pharms. 
Corp., 867 F. Supp. 2d 1241, 1252–53 (N.D. Ga. Mar. 6, 2023) (permitting treating 
physicians  to  testify  as  lay  witnesses  on  matters  that  may  resemble  expert 

testimony where such testimony is only “offered for the purpose of explaining the 
physician’s decision-making process or the treatment provided”); Tampa Bay 
Shipbuilding & Repair Co. v. Cedar Shipping Co., 320 F.3d 1213, 1218 (11th Cir. 
2003) (allowing project manager to testify as a lay witness to whether bill was 
reasonable for repairs to ship’s rudder).                                 
III.  DISCUSSION                                                          

    The Defendants seek to exclude the information contained in the Report 
appearing on page one under the heading “Cause of Ignition: Failure of equipment 
or heat source,” and the Narrative on page four wherein LT Desio writes that the 
homeowner identified the Thermacell Patio Shield as causing the fire. (Doc. 95, p. 
2  (quoting  Doc.  95-1,  pp.  1,  4)).  The  Defendants  incorrectly  characterize  the 

statements attributing the fire to the Patio Shield as opinions and mislabel the 
opinions as anonymous. The Defendants are correct in that LT Desio wrote in the 
Report that the homeowner stated the “fire started in the second[-]floor patio from 
a ‘Thermacell Patio Shield Mosquito Repellent’ device.” (Doc. 95-1, p. 4). And 
Defendants are also right that LT Desio could not recall if this information was 
obtained from the Plaintiff or Chief Wienckowski. (Doc. 95-8, 12:21–13:11; 18:12–

17). That said, Chief Wienckowski testified that he assumed LT Desio provided this 
information  from  the  homeowner.  (Doc.  95-7,  6:13–24,  9:14–21).  Chief 
Wienckowski also testified that he has no opinion concerning the cause of the fire. 
(Id. 7:14–20; 19:2–17).                                                   
    Since Chief Wienckowski is not the source of the contested statement in the 

Report, a simple process of elimination shows that LT Desio is. Accordingly, the 
information  is  not  anonymous.  It  is  also  not  an  opinion.  Neither  Chief 
Wienckowski nor LT Desio opine that the fire on the second-story balcony was 
caused  by  the  Patio  Shield.  They  merely  repeat  what  LT  Desio  believes  the 
homeowner said about the cause of the fire.2 And the homeowner’s statement is 
hearsay. The business records exception does not change this conclusion since the 

Plaintiff’s statement to LT Desio is hearsay within hearsay. See FED. R. EVID. 805. 
The Plaintiff, however, will be available to testify about the sequence of events 
culminating in the fire.3                                                 
    To  avoid  confusion,  the  Court  will  address  the  admissible  lay  witness 
opinions offered by LT Desio and Chief Wienckowski. LT Desio testified that her 

fire engine was first on scene around 8:19 p.m. (Doc. 95-8, 6:1–17, 9:7–17). When 
she arrived, fire was observed emitting from the rear balcony of the home located 
on the second floor. (Id. 29:20–24). LT Desio further testified that, based upon her 
observations at the scene, there is no indication that the fire began anywhere other 
than the second-floor patio. (Id. 40:12–20). LT Desio’s opinion that the fire began 
on the second-floor balcony is based on her personal observations as informed by 

26 years in the fire department and is properly admitted under Rule 701. See FED. 
R. EVID. 701. Chief Wienckowski also concluded from his personal observation that 
the fire started on the second-floor balcony. (Doc. 95-7, 8:22–23, 26:13–25). The 


2   LT Desio testified, “I can’t recall who exactly gave me the info but I wrote down what I was 
 told.” (Doc. 95-8, 12:21–13:11). An opinion, either expert or lay, requires more than merely 
 repeating what one is told by a third party.                            

3   The Plaintiff testified that around 7:15 p.m. on the night of the fire, she placed the Thermacell 
 Patio Shield on the table located on the second-story patio and turned it on. (Doc. 95-6, 29:16–
 19, 36:8–17, 39:4–18, 42:12–20). Around 7:30 p.m. to 7:45 p.m., her family sat down to 
 dinner, and by 8:00 p.m., a family member saw flames from the upstairs patio. (Id. 48:19–23, 
 49:7–18).                                                               
Chief also concluded the fire was accidental and testified there is no information 
to suggest this was an electrical fire. Ud. 27:23—-28:22). These lay witness opinions 
by LT Desio and Chief Wienckowski are based on their observations as informed 
by years of experience and are properly before the jury. 
IV.   CONCLUSION 
      For  these  reasons,  the  Defendants’  Revised  Daubert  Motion  to  Exclude 
Anonymous Opinions in Fire Rescue Report and Fire Chief Wienckowski’s Alleged 
Opinions (Doc. 95) is DENIED.4 
      DONE AND ORDERED in Orlando, Florida on July 22, 2025.

4   The Court has found that neither LT Desio nor Chief Wienckowski has offered opinions that 
   the Thermacell Patio Shield caused the fire, and so the Plaintiff may not represent such to the 
  jury in her opening statement.
