Pocatello Man Gets 33 Months for Sex Offender Registration Fail

Corry Blackmoon Bischoff, 39, of Pocatello, Idaho, is headed to federal prison after being sentenced to 33 months for failing to register as a sex offender—a lapse that stretched across state lines and nearly three years. The sentence, handed down yesterday in U.S. District Court in Boise, includes an additional five years of supervised release, marking the latest fallout from a criminal history that dates back two decades.

Bischoff pleaded guilty on September 13, 2016, to one count of failing to update his registration under the Sex Offender Registration and Notification Act (SORNA). The charge stems from his 1997 rape conviction in Madison County, Idaho, which legally bound him to keep authorities informed of his whereabouts. His last valid registration in Idaho was logged in August 2013. After that, the paper trail went cold.

In September 2013, the Idaho Commission of Pardons and Parole issued a warrant for Bischoff’s arrest after he violated parole conditions. Authorities lost track of him—until January 4, 2016, when officers with the Vancouver, Washington police apprehended him on the outstanding Idaho warrant. At the time of his arrest, Bischoff had neither updated his Idaho registration nor registered in Washington, where he had been living.

The failure to comply with SORNA isn’t a clerical oversight—it’s a federal felony. The law mandates that individuals convicted of sex offenses keep their registration current, especially when crossing state lines. Bischoff’s disappearance from the registry for over two years triggered a multi-agency manhunt and exposed flaws in inter-state offender tracking.

The investigation was led by the United States Marshals Service (USMS) in coordination with the Idaho Department of Correction, Bureau of Probation and Parole. Their joint efforts underscore the growing scrutiny on fugitive sex offenders and the bureaucratic cracks they often exploit.

U.S. Attorney Wendy J. Olson confirmed the sentencing, emphasizing that accountability doesn’t expire with time. For Bischoff, the cost of vanishing has been tallied: 33 months behind bars, followed by years under federal watch. His case serves as a stark reminder—once on the registry, you don’t drop off the map.
