49 F.4th 382
4th Cir.2022Background
- Undercover HSI detective downloaded child-pornography files from an IP traced to a Lord George Drive house where Arce was housesitting; police executed a warrant in May 2018.
- Officers interviewed Arce (in the house then briefly in a police vehicle), told him he was free to leave, and after questioning Arce admitted viewing child pornography and consented to a search of his apartment.
- Officers found an Alcatel phone with thumbnail images and videos; thumbnails formed the basis for four receipt counts and a possession count (multiple files).
- Forensics used Cellebrite to extract files and Griffeye hashing to compare images to a law-enforcement database; a Cellebrite report labeled some files as “Child Abuse Material / CAM.”
- At a bench trial the court credited the officers, denied suppression, admitted prior downloads from the Lord George IP under Rule 414, allowed lay testimony matching thumbnails to downloaded videos, convicted Arce, imposed 130 months, $5,000 restitution to a victim, and multiple supervised-release conditions including a lifetime internet/computer ban.
- Fourth Circuit: affirmed Miranda/custody ruling; held parts of the Cellebrite report were testimonial (Confrontation Clause) but the error was harmless; upheld other-evidence and lay-opinion admissions and restitution; reversed/remanded the lifetime internet/computer ban and clarified no ban on incidental contact with minors.
Issues
| Issue | Arce's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether interview was custodial (Miranda) | Arce said he was effectively detained, handcuffed, and threatened; confession involuntary without Miranda warnings | Officers said guns not drawn, told Arce he was free to leave, interview brief and noncustodial | Not custodial: district court credibility findings affirmed; Miranda not required before initial questioning |
| Admission of Cellebrite/Griffeye report (Confrontation Clause) | Report’s labels (e.g., “CAM”) are testimonial—law-enforcement judgments—so admitting them violated Crawford | Much of the report is machine-generated, non-testimonial; any labels duplicative of admitted images and lay testimony | Labels identifying matches to known child-pornography were testimonial and inadmissible, but error was harmless beyond a reasonable doubt given the graphic admitted images and lay testimony |
| Admission of other downloads from Lord George IP (Rule 414) | Arce argued government failed to provide required pretrial notice of intent to use Rule 414 evidence | Rule 414(b) requires disclosure of the evidence itself (not separate proffer of purpose); evidence was disclosed months earlier | Evidence admissible under Rule 414; no separate 404(b)-style notice requirement; admission proper |
| Lay-opinion testimony matching thumbnails to videos (Rule 701) | Arce contended Detective Simpson had no specialized basis and testimony was no more helpful than the judge’s own view | Simpson had personal perception from viewing the videos and thumbnails; testimony aided the trier-of-fact | Admissible under Rule 701; district court did not abuse discretion in admitting lay comparisons in a bench trial |
| Restitution to the identified victim (18 U.S.C. § 2259; Paroline) | Arce challenged amount and causal connection to victim’s alleged losses | District court relied on expert reports, Paroline factors, and defendant’s conduct to set an amount | Restitution order affirmed as within broad discretion; Paroline factors considered despite imprecision |
| Supervised-release conditions (lifetime internet/computer ban; pornography ban; no-contact with minors) | Lifetime internet/computer ban and sweeping contact ban are overbroad and not the least restrictive | Court argued internet/computer access related to offense; pornography and contact restrictions needed to protect public | Lifetime total ban on internet/computer use reversed and remanded for tailoring; pornography ban upheld; no-contact-with-minors condition reasonable but must exclude incidental/unintentional contacts and be clarified regarding employment access |
