A professor was shot and killed on the University of Arizona campus in Tucson on Wednesday, campus police said.
The campus police chief said a male professor in the Department of Hydrology was shot and killed by a former student. The suspect was identified by police as Murad Dervish. The professor has not been identified.
Dervish, 46, was arrested following a traffic stop by the state Department of Public Safety near the town of Gila Bend, University of Arizona Police Chief Paula Balafas said during a news conference.
Police said the suspect used a handgun.
The victim was taken to a local hospital but was pronounced dead by medical personnel, Balafas said.
Police responded to the campus’ John W. Harshbarger Building “for a shooting,” University of Arizona Police said on Twitter shortly after 2 pm local time on Wednesday.
Police did not issue a lockdown, but warned people to stay away from the building and the surrounding area.
“The male suspect was identified but no longer at the scene. Police are currently searching for him,” University of Arizona police had said, describing the suspect as being in his mid-30s with short brown hair and wearing a blue baseball cap and with a dark backpack.
All remaining classes held at the school’s main campus were canceled Wednesday, police said.
