BOZEMAN — A Bozeman man who left the police station while being questioned in a sexual assault case has waived extradition from Oregon, where he was arrested last week.
Kevin Briggs, 28, waived extradition in Multnomah County Circuit Court in Portland, Ore., on Tuesday morning.
Gallatin County Attorney Marty Lambert said he's not sure when Briggs will be returned to Bozeman, where he faces charges of attempted sexual intercourse without consent, aggravated assault, assault on a peace officer and escape.
Officers say Briggs walked out of an unlocked interview room during a shift change early on Feb. 1. He was arrested after his former girlfriend called police to say Briggs had attacked her in her apartment.
He was able to get a ride to Missoula where officials believe he bought a bus ticket to Spokane, Wash., and left the next day. The FBI said Briggs told an acquaintance he intended to travel to Seattle, south to Mexico and then take a ship to Russia, which does not have an extradition treaty with the U.S.
Gallatin County Justice Court issued a $500,000 warrant for his arrest while the FBI offered a $10,000 reward. The FBI said Briggs was seen in Northern California two weeks ago. He was arrested in Portland on Friday night.
A federal charge of unlawful flight to avoid prosecution was dismissed by U.S. Magistrate Jeremiah Lynch on Monday.
Briggs' mother, Kathleen Ely of Helena, Mont., said her son was required to register as a sex offender after being convicted of kidnapping and sexual intercourse without consent involving his 14-year-old former girlfriend in Helena in 2003, when he was 16.
"It makes it seem like he's a predatory guy and he's not," Ely said of her son, whom she said was a senior in biochemical engineering with a 3.92 grade point average.
Officials at Montana State University confirm Briggs was a student at the time of the alleged assault, but school officials say he is no longer enrolled.
