2 Opinion of the Court 23-14112

Before JILL PRYOR, BRANCH, and BLACK, Circuit Judges.

PER CURIAM:

Quinton L. Pete appeals his convictions for attempted 

Hobbs Act robbery and possession of a firearm and ammunition by 

a convicted felon. First, Pete asserts the district court reversibly 

erred by denying his request for a Daubert1 hearing to test the admissibility of the Government’s ballistics toolmark identification 

evidence and testimony. Second, Pete contends the court reversibly erred by excluding or restricting testimony from his firearms 

ballistics expert who was qualified to testify on the subject. Third, 

Pete asserts the court violated his rights under the Confrontation 

Clause by admitting, over his objection, hearsay testimony that an 

unidentified, independent toolmark examiner reached the same 

conclusion as the Government’s expert toolmark witness. We address each of his challenges in turn, and after review, affirm his convictions.

I. DAUBERT HEARING

Rule 702 of the Federal Rules of Evidence allows a witness 

who is qualified as an expert to give testimony so long as:

(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; 

1 Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993).

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 2 of 9
23-14112 Opinion of the Court 3

(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 (version effective to November 30, 2023). In this 

Circuit, scientific expert testimony is admissible if:

(1) the expert is qualified to testify competently regarding the matters he intends to address; (2) the 

methodology by which the expert reaches his conclusions is sufficiently reliable as determined by the sort 

of inquiry mandated in Daubert; and (3) the testimony 

assists the trier of fact, through the application of scientific, technical, or specialized expertise, to understand the evidence or to determine a fact in issue.

United States v. Ware, 69 F.4th 830, 845-46 (11th Cir. 2023), cert. denied, 144 S. Ct. 1395 (2024) (quotation marks omitted). The party 

seeking to introduce the expert opinion has the burden of establishing the three prongs: qualification, reliability, and helpfulness. Id. 

at 846. District courts consider four factors within the reliability 

prong “(1) whether the expert’s theory can be and has been tested; 

(2) whether the theory has been subjected to peer review and publication; (3) the known or potential rate of error of the particular 

scientific technique; and (4) whether the technique is generally accepted in the scientific community.” Id. (quotation marks omitted). Courts are not required to hold a Daubert hearing in every 

case where a party challenges the admissibility of expert testimony.

4 Opinion of the Court 23-14112

Id. The Daubert inquiry provides the district courts, which are 

much more familiar with the facts and needs of a case, the flexibility 

“to manage their dockets and counsels’ time to provide the most 

efficient and just resolution of issues.” Id. 

In Ware, prior to trial, the defendant sought to exclude expert testimony regarding fingerprint evidence because new reports, from the National Research Council (NRC) and the President’s Council of Advisors on Science and Technology (PCAST), 

stated that fingerprint analysis was unreliable and susceptible to 

cognitive biases. Id. at 840. The district court denied Ware’s motion and determined that a hearing under Daubert was unnecessary, 

in part, because he failed to present a case from our Court or another district court in the Circuit that favored excluding fingerprint 

evidence under Daubert. Id. Ware asserted the district court 

abused its discretion by admitting the challenged evidence without 

holding a formal Daubert hearing. Id. at 835. He challenged the 

reliability of the fingerprint analysis generally, and not the qualifications of the Government’s expert or the helpfulness of his testimony. Id. at 846. This Court held the district court was not required to hold a Daubert hearing before admitting the Government’s fingerprint expert and did not abuse its discretion in deciding such a hearing was unnecessary. Id. at 847. Noting the district 

court had “considered the reports and arguments presented and 

found that fingerprint evidence was reliable enough as a general 

matter to be presented to the jury,” we reasoned fingerprint evidence has long been accepted in our Circuit and that the cure for 

questionable, but admissible, evidence is cross-examination, not 

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 4 of 9
23-14112 Opinion of the Court 5

exclusion. Id. at 847-48. This Court added the PCAST and NRC 

reports may cast doubt on the error rates of the fingerprint analysis 

but they go to the weight given to the analysis rather than the legitimacy of the practice. Id. at 848.

The district court did not abuse its discretion in denying 

Pete’s request for a Daubert hearing regarding the admissibility of 

the Government’s ballistics toolmark identification evidence and 

testimony. See Ware, 69 F.4th at 845 (reviewing the district court’s 

decisions regarding the admissibility of expert testimony, the reliability of an expert opinion, and the denial of a Daubert hearing for 

abuse of discretion). The court held a conference on the issue, permitted the parties to submit any additional documents and arguments on the issue, and decided the issue in a detailed order discussing each of the Daubert factors. The court also determined the 

parties’ schedules did not permit time for a Daubert hearing prior 

to trial, and, therefore, the trial would have been pushed back if the 

court had conducted a Daubert hearing. Although Ware revolved 

around the admissibility of fingerprint evidence, the court did not 

err in relying on Ware in deciding whether to hold a Daubert hearing, because Ware also involved a challenge to the reliability of a 

commonly used forensic science method. Ware, 69 F.4th at 846. In 

the order, the court looked to Ware on the issue, but conducted its 

own detailed Daubert analysis based on the unique facts, evidence, 

and arguments the parties presented. Ware supports the district 

court’s finding that Firearm Toolmark Identification (FTI) evidence is sufficiently reliable to present to the jury and that crossexamination was the proper means to attack the expert testimony’s 

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 5 of 9
6 Opinion of the Court 23-14112

reliability. Id. at 847-48. Particularly, FTI evidence continues to be 

used in federal courts after the PCAST Report and NRC Report 

criticized the existing studies of its reliability, and Pete did not provide a federal court decision that prohibited FTI evidence based on 

Daubert. Additionally, other courts of appeals have upheld the admissibility of FTI evidence. See United States v. Hunt, 63 F.4th 1229,

1249 (10th Cir. 2023); United States v. Brown, 973 F.3d 667, 704 (7th 

Cir. 2020); United States v. Johnson, 875 F.3d 1265, 1280-81 (9th Cir. 

2017); United States v. Williams, 506 F.3d 151,162 (2d Cir. 2007). 

In his motion for a Daubert hearing and to exclude the Government’s FTI evidence, Pete attacked the reliability of FTI broadly 

and contended it was not credible enough to meet the Daubert reliability requirements. The court adequately addressed that argument in analyzing the proposed evidence under each of the Daubert 

considerations. The court found that Andrew Pike was qualified 

to provide the FTI testimony of his findings because of his training 

and experience, including his role as a firearms toolmark examiner 

with Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). 

It found that Pike’s testimony on the connection between the firearm found in Pete’s possession and the shell casings found at the 

scene of the shooting would help the jury, particularly because 

such information was relevant to the crimes charged and was beyond the expertise of the jury. See Fed. R. Evid. 702; Ware, 69 F.4th 

at 845-46. The court’s extensive reliability analysis considered the 

four factors under the reliability prong. Ware, 69 F.4th at 846. 

While acknowledging the critiques, the court found the methodology had been tested, subjected to peer review and publication, and 

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 6 of 9
23-14112 Opinion of the Court 7

had a known error rate. The court found the Association of Firearm Toolmark Examiners methodology continued to be generally 

accepted in the firearm expert community, despite the criticisms 

raised in the report and studies on which Pete relied.

In sum, the district court did not apply an incorrect legal 

standard, follow improper procedures in making its determination, 

or make findings of fact that were clearly erroneous. See United 

States v. Harris, 989 F.3d 908, 911 (11th Cir. 2021) (“A district court 

abuses its discretion if it applies an incorrect legal standard, follows 

improper procedures in making the determination, or makes findings of fact that are clearly erroneous.” (quotation marks omitted)). 

Accordingly, we affirm as to this issue. 

II. LIMITING EXPERT TESTIMONY

Daubert’s gatekeeping function applies to all expert testimony. Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 147 (1999). 

The helpfulness prong of the Daubert analysis looks to whether expert testimony “concerns matters that are beyond the understanding of the average lay person.” United States v. Frazier, 387 F.3d 

1244, 1262 (11th Cir. 2004). Further, “[p]roffered expert testimony 

generally will not help the trier of fact when it offers nothing more 

than what lawyers for the parties can argue in closing arguments.” 

Id. at 1262-63.

The district court did not abuse its discretion in limiting J. 

Christopher McKee’s expert testimony. The district court followed 

the Daubert analysis, conducted a hearing on the issue, and made 

reasonable findings that some of McKee’s proposed testimony was 

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 7 of 9
8 Opinion of the Court 23-14112

beyond his expert scope and some of it was unhelpful to the jury, 

and therefore, the court did not apply an incorrect legal standard, 

follow improper procedures in making its determination, or make 

findings of fact that were clearly erroneous. See Harris, 989 F.3d at 

911. Additionally, on appeal, Pete asserts new topics on which 

McKee would have testified that he failed to raise in the district 

court. Accordingly, we affirm as to this issue.

III. CONFRONTATION CLAUSE

We examine whether a statement is testimonial under the 

Confrontation Clause de novo. United States v. Caraballo, 595 F.3d 

1214, 1226 (11th Cir. 2010). We will excuse a violation of the Confrontation Clause if the error is harmless beyond a reasonable 

doubt. Delaware v. Van Arsdall, 475 U.S. 673, 684 (1986). Whether 

error is harmless depends upon numerous factors, including “the 

importance of the witness’ testimony in the prosecution’s case, 

whether the testimony was cumulative, the presence or absence of 

evidence corroborating or contradicting the testimony of the witness on material points, the extent of cross-examination otherwise 

permitted, and . . . the overall strength of the prosecution’s case.” 

Id. Further, “[t]o require a new trial . . . [a] significant possibility 

must exist that, considering the other evidence presented by both 

the prosecution and the defense, the . . . statement had a substantial 

impact upon the verdict of the jury.” United States v. Ransfer, 

749 F.3d 914, 927 (11th Cir. 2014) (quotation marks omitted).

Even assuming without deciding that Pete’s rights under the 

Confrontation Clause were violated when Pike testified on redirect 

USCA11 Case: 23-14112 Document: 29-1 Date Filed: 09/04/2024 Page: 8 of 9
23-14112 Opinion of the Court 9

examination that an unidentified, independent toolmark examiner 

reached the same conclusion as he did, any potential error was 

harmless beyond a reasonable doubt, because the Government 

presented substantial evidence of Pete’s guilt. The Government’s 

evidence included information extracted from Pete’s cellphone 

that the phone was in the parking lot of the Coyote Sports Bar at 

the time of the shooting and then traveled west. The phone also 

showed a google search for “Two Shot Outside of Pensacola Bar” 

around 5:30 p.m. on the day of the shooting and revealed that two 

articles on the Coyote Sports Bar shooting were viewed. Pete was 

also found with the same type of gun and ammunition that was 

used in the shooting, and he met the general description provided 

by the victims. There is not a significant possibility that Pike’s 

statement confirming the peer-reviewer’s findings at the end of his 

re-direct examination had a substantial impact on the guilty verdict, such that a new trial should be required. See Ransfer, 749 F.3d 

at 927. Notably, Pete does not challenge any other portion of Pike’s 

testimony as violating the Confrontation Clause, and therefore, the 

jury properly heard Pike’s finding, as an ATF examiner, that the 

gun found at Pete’s arrest was the gun used to shoot the victims. 

Based on the overall strength of the prosecution’s case, any potential Confrontation Clause violation was harmless beyond a reasonable doubt.

Accordingly, we affirm as to this issue.

AFFIRMED.
