Panel
Before: R. NELSON, MILLER, and DESAI, Circuit Judges.
Adam Phipps was convicted by a jury of attempted receipt and possession of
child pornography. See 18 U.S.C. §§ 2252(a)(2), (a)(4)(B). He appeals his
conviction and the revocation of his supervised release, arguing that the district
court admitted improper expert testimony and hearsay evidence.
1. The district court did not err by allowing Officer Mar to testify as an
expert regarding his imaging of Phipps’s computer using two forensic tools—
Forensic Falcon and Axiom. “Whether the district court applied the correct legal
standard under Daubert is reviewed de novo, and the district court’s decision to
admit expert testimony is reviewed for abuse of discretion.” Hardeman v.
Monsanto Co., 997 F.3d 941, 960 (9th Cir. 2021). First, it was not an abuse of
discretion to conclude that Officer Mar was qualified by his training and expertise.
United States v. Holguin, 51 F.4th 841, 854 (9th Cir. 2022). Officer Mar had over
400 hours of training, including on the proper use of the forensic tools. He also
had notable experience, having conducted at least 15 and 25 prior forensic
examinations using Forensic Falcon and Axiom, respectively. “The fact that
[Officer Mar] lacked an advanced degree, supervisory experience, previous
experience as an expert witness, or relevant publications did not render [him] unfit
to provide expert testimony.” United States v. Brooks, 610 F.3d 1186, 1196 (9th
Cir. 2010).
Panel 2 21-50168
Second, the district court expressly found that Officer Mar reliably applied
his expertise to the facts in the case. Officer Mar carefully described the way he
digitally examined Phipps’s laptop, and FBI Agent Evans (whom Phipps concedes
was a qualified expert) found no fault with Officer Mar’s forensic imaging. At
bottom, the district court properly performed its “gatekeeping duty” in ensuring
that Officer Mar’s expert testimony was relevant and reliable. United States v.
Ruvalcaba-Garcia, 923 F.3d 1183, 1190 (9th Cir. 2019) (per curiam).
2. We do not decide whether the district court abused its discretion by
admitting emails suggesting that Phipps had purchased a laptop without the
required authorization from his probation officer. Phipps’s purchase and use of the
laptop were proven by substantial independent evidence. Probation Officer Paula
Burke testified that during the probation search of Phipps’s workplace, she found
the Toshiba laptop in the section of the break room where Phipps was temporarily
residing. Nearby, she found a note containing words that Phipps used as
passwords in the past. FBI Agent Evans also testified that he obtained various
business records and GPS data, confirming the sale, delivery, and retrieval of the
Toshiba laptop. Thus, any error in admitting the emails was harmless. United
States v. Seschillie, 310 F.3d 1208, 1214 (9th Cir. 2002).
3. Phipps also argues that his Daubert and hearsay arguments justify
reversing the revocation for the same reasons as the conviction. Those arguments
Panel 3 21-50168
fail for the reasons we have already discussed. Thus, Phipps’s arguments do not
support a challenge to the revocation, and the district court did not abuse its
discretion.
AFFIRMED.
