United States v. Ross

Summary

Kevin Lee Ross, on supervised release from a 2014 child-pornography conviction, was charged with and convicted of possessing child pornography again after probation officers found over 1,380 CSAM files across an unauthorized cell phone, laptop, and external hard drive. Before trial, Ross stipulated that nine specific government exhibits were child pornography produced using actual minors. He then objected under Fed. R. Evid. 403 when the government moved to publish those nine exhibits and to have HSI Agent Kelly describe them in his forensic testimony. The district court overruled the objection, relying on Ross I (2016) and Old Chief's rule that the prosecution is entitled to the 'full evidentiary force' of its case. Ross's defense was that he did not know the devices or their contents — a denial that kept 'possession' and 'knowledge' squarely at issue notwithstanding the stipulation. The First Circuit affirmed. The limited publication (six images + three short video clips) had probative value for possession and knowledge that the stipulation did not supply, and Agent Kelly's descriptions served the same purpose. No abuse of discretion under Rule 403.

Structured facts

Parties

Petitioner/Appellant: Kevin Lee Ross (defendant-appellant)
Respondent/Appellee: United States

Jurisdiction

federal — First Circuit on appeal from the District of Maine

Statutes cited

18 U.S.C. § 2252A(a)(5)(B), 18 U.S.C. § 2252A(b)(2), 18 U.S.C. § 2256(8)(A), Fed. R. Evid. 403, Fed. R. Crim. P. 52

Issue

Whether a stipulation that specific files are child pornography precludes the government under Rule 403 from publishing the files and having its forensic agent describe them, given the defendant's denial of possession and knowledge.

Holding

No. The stipulation did not eliminate the probative value of showing and describing a limited representative sample, because the defendant's denial of possession and knowledge kept those elements squarely in dispute.

Outcome

affirmed

Vote

unanimous panel (Montecalvo, Thompson, Aframe)

Judge Thompson

Key facts

• Ross had a 2014 child-pornography conviction and was on supervised release with internet-use restrictions.
• Probation officers searched Ross's home and car and found an unauthorized cell phone (with a CSAM image in view when airplane mode was enabled), a laptop, and an external hard drive, collectively holding 1,380+ CSAM files.
• Parties stipulated before trial that nine government exhibits depicted actual minors and were produced using materials transported in interstate commerce.
• At trial, Ross objected to the government publishing the stipulated exhibits and to Agent Kelly describing them.
• Jury convicted; Ross was sentenced to 121 months plus 24 months consecutive for the supervised-release violation.

Reasoning

Under Old Chief, a defendant generally cannot 'stipulate his way out' of the government's full evidentiary presentation. When the defense theory puts possession and knowledge in issue, visual proof of CSAM across all three devices is probative on: (a) whether the same owner possessed all three devices (inferred from common 'type' of files + mundane Ross-interest search data), and (b) whether anyone in possession would have known the contents (the CSAM was readily visible on the cell phone at a single power-on). Limiting the display to nine files out of 1,380 — six images plus three short videos — was within the court's broad Rule 403 discretion. Agent Kelly's descriptive testimony served the same valid, non-cumulative purpose.

Implications

The decision closes one of the few remaining openings defense counsel had for cabining CSAM evidence via stipulation in possession cases where the defendant denies knowledge. Three implications. First, defense counsel should not rely on stipulations alone to keep CSAM images from the jury whenever possession and knowledge are contested. Second, prosecutors can continue to present a limited but real sample of CSAM, even with a stipulation, so long as the display is calibrated to probative value and the district court engages in a meaningful Rule 403 analysis on the record. Third, the opinion reinforces Ross I's recurring doctrinal role in the First Circuit: the 'proposed/actual stipulation' distinction is not outcome-determinative when the defendant puts possession or knowledge at issue. Importantly, the panel flags a future case where voluminous CSAM introduction despite a stipulation might tip toward unfair prejudice — litigation strategy should continue to police the volume, not just the fact, of display.

Practical guide

For federal defense counsel in CSAM possession cases: (1) stipulate but keep pressure on volume and manner of display — Rule 403 arguments should focus on the marginal prejudicial value of each exhibit beyond the stipulated fact; (2) consider conceding possession and knowledge if you want stipulations to carry more weight — the Ross/Dudley rule is triggered precisely by defendant denials. For federal prosecutors: calibrate CSAM evidence to the minimum needed to prove possession and knowledge; a representative sample across all charged devices is defensible, but avoid cumulative presentation. For district judges: make Rule 403 balancing on the record, noting specifically why the defendant's defense theory keeps the stipulation from fully substituting for evidence. For US Probation officers managing supervised release on sex offenses: the factual pattern here — random inspections plus a sibling tip — proved effective; maintain graduated screening procedures and document third-party tips carefully.
