Hundreds of law enforcement officers, including those from the FBI, were combing the canyons of Utah’s Wasatch Mountains early Tuesday after a fatal carjacking led to the lockdown of the University of Utah’s Salt Lake City campus. University authorities told students to “shelter in place” as police launched a manhunt, which was sparked after a woman came to campus cops and told them she was assaulted by her husband while they were camping in Red Butte Canyon. Shortly afterward, police say her husband, Austin J. Boutain, 24, shot and killed someone during a carjacking in the mouth of the canyon and was at large. Salt Lake City Police Sgt. Brandon Shearer confirmed that one person was dead but gave no further details about the circumstances of the shooting. Classes at the University of Utah were canceled Tuesday; the lockdown was lifted just before 3 a.m.
