Background
During a routine probation-compliance check at registered sex offender Scott Michael Nelson’s home, Tennessee probation officers searched his Alcatel flip phone under a warrantless-search condition of his probation. They found a video composed of six sexually explicit still images of a minor female. Nelson admitted that the phone was his but denied owning or knowing about the video. Police seized the phone, obtained a warrant, and recovered the video through forensic extraction.
A jury convicted Nelson of knowingly possessing child pornography under 18 U.S.C. § 2252A(a)(5)(B). The government’s evidence included the video, a thumbnail, Cellebrite extraction reports, and personal images from the phone. A government expert testified that the video followed the phone’s sequential file-naming convention and was created around the same time as images of Nelson’s paychecks and license plate. Nelson presented competing expert testimony about when thumbnails are generated and whether the video had previously been viewed. He moved for acquittal after the government’s case but declined to renew that motion after presenting his defense or after the government’s rebuttal. The district court sentenced him to 120 months in prison.
The Court’s Holding
The Sixth Circuit affirmed. Because Nelson did not renew his Rule 29 motion at the close of all the evidence, the court reviewed his sufficiency challenge only for a manifest miscarriage of justice—whether the record was devoid of evidence pointing to guilt. That demanding standard was not met. Nelson owned and had registered the phone, the video was stored in an application rather than inaccessible space, its file name followed the phone’s sequential naming pattern, and it was created near the time of Nelson’s personal photographs. The jury was entitled to infer knowing possession from that circumstantial evidence and to credit the government’s experts over Nelson’s expert.
The court also found no plain error in admitting the video, thumbnails, cached data, Cellebrite reports, and related digital evidence because Nelson had not objected at trial. The evidence was relevant to knowing possession, and its probative value was not substantially outweighed by unfair prejudice or juror confusion. Nelson’s Rule 702 argument failed because he identified no unreliable expert methodology and instead disputed the inferences drawn from the evidence.
Finally, the district court did not reversibly err by declining to give Nelson’s requested theory-of-defense instruction in full. The instruction actually given told jurors that Nelson denied guilt and maintained that the government had not proved knowing possession beyond a reasonable doubt. That substantially covered his legal defense; the omitted language merely presented his preferred view of the facts, which the court was not required to include.
Key Takeaways
- A defendant who presents evidence after an unsuccessful Rule 29 motion must renew the motion at the close of all evidence to preserve ordinary sufficiency review.
- Ownership and control of a device, combined with file location, naming patterns, creation dates, and related personal data, can support an inference of knowing possession.
- Disagreement over competing forensic interpretations generally concerns evidentiary weight and witness credibility, matters reserved for the jury.
- A theory-of-defense instruction need not recite the defendant’s preferred factual interpretation when the jury charge already covers the governing legal defense.
Why It Matters
The decision illustrates how procedural defaults can sharply narrow appellate review. Nelson’s failure to renew his acquittal motion required him to show that the record contained no evidence pointing to guilt, rather than merely arguing that the government’s proof was insufficient under ordinary de novo review.
It also confirms that digital-forensic artifacts need not conclusively establish a defendant’s mental state to be admissible. When such evidence has some tendency to support knowledge and is explained through expert testimony, competing interpretations ordinarily go to weight and credibility rather than admissibility.
