952 F.3d 954
8th Cir.2020Background
- From Sept. 2014–Mar. 2015, law enforcement using undercover BitTorrent downloads tied dozens of child-pornography files to two IP addresses at Fechner’s home; additional downloads occurred in Apr. 2015.
- Forensic exam of Fechner’s phone and SD card showed extensive child-pornography activity: files moved to the SD card, deleted, and recoverable only as thumbnails and short video fragments whose hash values matched known child-pornography files.
- Because many original files on Fechner’s devices were deleted/unplayable, the government introduced three independently downloaded BitTorrent videos (matching names, thumbnails, lengths, and hashes) as demonstratives to identify the deleted files.
- The government also offered a Rule 1006 summary (Exhibit 6) of 36 downloaded video files to avoid presenting voluminous pornographic material, and over 400 non-pornographic but sexualized images of minors (“child erotica”) were recovered on the SD card.
- Fechner testified he was a BitTorrent expert who denied knowingly downloading or sharing child pornography; trial evidence included short video clips, the Rule 1006 summary, and the child erotica images. The jury convicted on all counts.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of independently downloaded videos (Rule 403 relevance/prejudice) | Independently downloaded clips are unfairly prejudicial and do not prove Fechner knew his devices contained child pornography. | Clips are probative to identify unplayable files on Fechner’s devices and make knowledge more likely (matching hashes/thumbnails). | Admissible: short clips were probative and not unfairly prejudicial; district court did not abuse discretion. |
| Admissibility of Rule 1006 summary (Exhibit 6) | Summary included brief descriptions of videos not previously admitted; hearsay and introduced evidence not in record. | Summary fairly summarizes voluminous evidence, the preparer viewed videos, and it assisted the jury; underlying evidence was available for cross. | Admissible under Rule 1006; even if error, inclusion of descriptions was harmless given other evidence. |
| Admissibility of child erotica images (intrinsic evidence vs. Rule 404(b)) | Images are improper propensity evidence offered only to show bad character and are unduly prejudicial. | Images are relevant to knowledge/motive because items had to be manually moved to SD card and were co-located with deleted child-pornography artifacts. | Not intrinsic, but admissible under Rule 404(b): relevant to knowledge/motive; any error in admission was harmless. |
| Limiting instruction for child erotica (plain-error review) | Limiting instruction was unclear and insufficient to cure prejudice. | Court gave immediate limiting language and a standard 404(b) final instruction that cured any prejudice. | No plain error: instructions, including final 404(b) charge, were adequate; conviction stands. |
