United States v. Bruce Niggemann, 881 F.3d 976

In 2014 Homeland Security agents traced IP address 24.1.138.60, using Ares peer-to-peer software to share child pornography, to Bruce Niggemann's Comcast account.
Agents downloaded a video from the account showing prepubescent sexual activity; Niggemann had a 1994 conviction for long-term sexual abuse of minors.
A search warrant for Niggemann’s home seized a desktop and laptop; forensic review found 40 child‑pornography videos (36 in a "temp" folder on the desktop) and Ares registered to "Bruce Niggemann" and his business email.
Forensic evidence tied the computers to Niggemann (business/financial files, email shortcut colocated with Ares shortcut, a draft obituary saved 45 minutes before creation of the "temp" folder); Ares history showed thousands of child-pornography–related downloads.
Niggemann waived a jury; at a bench trial the government presented agent testimony and stipulated evidence of Niggemann’s prior sexual‑abuse conviction; defense presented no evidence and the judge convicted on receipt and possession counts under 18 U.S.C. § 2252A.
Sentenced to 182 months (above the 15‑year statutory minimum triggered by his prior conviction but below the Sentencing Guidelines range). Niggemann appealed on sufficiency and Eighth Amendment grounds.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of evidence that Niggemann, not someone else, used the computers	Prosecution: forensic links (account registration, file locations, personal files) and Niggemann’s statements and prior abuse establish ownership and use	Niggemann: computers were in an open room, not password protected, wife had access; government failed to prove he personally downloaded/viewed files	Affirmed — ample direct and circumstantial forensic evidence plus statements and prior conviction support conviction beyond a reasonable doubt
Non‑exclusive computer possession doctrine applicability	Prosecution: account and files uniquely tied to Niggemann distinguish this from non‑exclusive cases	Niggemann: similar to Moreland and Lowe where other users plausibly accessed the device	Affirmed — facts materially differ from Moreland/Lowe; inferences support conviction
Sentencing Eighth Amendment proportionality challenge	Prosecution: sentence justified by Congress’s policy, severity of child‑pornography harms, and defendant’s prior hands‑on abuse	Niggemann: 182 months (effectively life) is grossly disproportionate given age, old prior conviction, and offenses were receipt/possession not distribution	Affirmed — claim foreclosed by precedent; sentence not grossly disproportionate
