Oct. 31 (UPI) -- The man suspected of killing a student at the University of Utah -- and who also is a suspect in a Colorado homicide -- has been arrested, authorities said Tuesday.
The gunman was identified by police as Austin Jeffery Boutain. Police say he shot and killed a woman late Monday during a carjacking attempt near the college campus.
A manhunt involving at least eight security agencies, hundreds of officers and the FBI concluded Tuesday, when a librarian noticed Boutain, 24, on the third floor of the main Salt Lake City library and called security. Police said Boutain surrendered peacefully and was detained just after 1 p.m.
Boutain has a criminal history -- having been charged eight times in Marion County, Ala., since 2015 for crimes including theft, manufacturing of a controlled substance, attempt to elude police and failing to register as a sex offender.
A manhunt for Boutain began after a woman told Salt Lake City police that Boutain, her husband, assaulted her while they were camping near the school. As she was being treated, authorities said, Boutain shot and killed a student in a carjacking attempt.
Boutain's wife, Kathleen, is also a suspect in the Colorado homicide and has been jailed on separate drug and theft charges.
Authorities identified Monday night's victim as CheinWei Guo, a 23-year-old international student. Classes were canceled Tuesday in her honor.
"We have canceled classes today in respect of ChenWei and the impact this violent event has had on our campus community," University of Utah President David Pershing said in a letter.
