United States v. Manning, 361 F. Supp. 3d 839

Background

In August 2016 Omegle's moderation team flagged a video snapshot depicting an adult woman sexually abusing a young child and submitted a CyberTip (with 12 snapshots and an IP address) to NCMEC, which forwarded it to the Minnesota BCA.
BCA Special Agent Dawn Johnson reviewed the snapshots, matched 11 other snapshots from the same webcam/IP showing a white male she identified as Ryan Manning, traced the IP to Manning's residence, and conducted surveillance linking Manning to the address.
On December 15, 2016 Judge Oleisky issued a search warrant for Manning’s residence, vehicles, and electronic devices based on Agent Johnson’s affidavit; the warrant was executed December 16, 2016 and electronic evidence of child pornography was seized.
During the search Agent Johnson interviewed Manning in a small room after telling him he was not under arrest and was free not to speak; Manning made incriminating statements and cooperated (gave passwords, identified devices).
Manning moved to suppress the seized evidence (challenging probable cause and staleness) and his statements (arguing custodial interrogation/Miranda violation); Magistrate Judge Schultz recommended denying suppression and the district judge adopted that recommendation (with somewhat different reasoning).

Issues

Issue	Plaintiff's Argument (Gov't)	Defendant's Argument (Manning)	Held
Probable cause for warrant to search residence and devices	Affidavit linked the flagged CyberTip (child‑sex snapshot) to Manning by IP, webcam, photos, and surveillance; expert testimony supported likelihood collectors retain material	Affidavit was speculative/"bare bones": single image, no date clarity, no independent corroboration of collecting/possessing child pornography	Denied suppression — affidavit provided substantial basis for probable cause; Leon good‑faith applies if needed
Staleness of CyberTip/evidence	Child pornography is typically hoarded; multi‑month gaps do not render information stale	At least five months passed and affidavit failed to specify when the offending chat occurred, so information is stale	Denied — courts give weight to hoarding tendency; lapse not fatal under circumstances
Whether single intercepted image suffices to infer ongoing collection	Single streamed image combined with same webcam/IP snapshots, identification, and expert opinion supports inference of ongoing possession	A single streamed image without corroboration cannot support inference of collector/possession at home	Denied — single image can suffice when tied to suspect and considered with context and expertise
Miranda/custodial interrogation	Interview was non‑custodial: agent told Manning he was not in custody, he voluntarily acquiesced and could have left; room not so police‑dominated	The environment (multiple armed officers, intercepted in vehicle, door partly blocked, told he couldn’t leave with truck) was police‑dominated and effectively custodial	Denied suppression — totality shows a reasonable person would feel free to terminate and leave; not custodial
