The FBI was earlier asking for the public's help in locating the fugitive who was thought to possibly be making his way through Southern California.
Kevin Anthony Briggs, 28, a convicted felon and registered sex offender, was believed to be headed to Mexico from the San Francisco area.
Briggs is accused of attacking a woman and a police officer in Bozeman, Montana.
He escaped from police last week, and is also known as Aimee MacIntire, Kevin Bacon, Kevin A. Briggs, Timothy McCoy, James Meismer, James Zenon Meismer.
Briggs was wanted for numerous charges including aggravated assault, attempted sexual intercourse without consent, assault on a police officer and escape. Briggs was also wanted on federal charges of unlawful flight to avoid prosecution.
Authorities believe Briggs purchased a one-way bus ticket to Spokane, Washington, on Feb. 1 from Missoula, Montana. He was considered armed and dangerous and had last been seen in San Francisco, Berkeley and Oakland.
A $10,000 reward was offered for information leading to his arrest. The FBI said Briggs may have been staying in homeless shelters.
Briggs was described as a white male, standing 5 feet 5 inches tall and weighing about 135 pounds. He has brown hair and hazel eyes. He also has a sunburst tattoo around his right nipple, a tattoo in his armpit and a tattoo on his lower lip. He has a double "snake bite" piercing on his bottom lip, a belly button piercing and pierced ears.
The suspect was last seen wearing gray sweatpants, a dark-colored hooded jacket or parka, black shoes and a dark baseball cap.
