Professor killed in shooting

A University of Arizona professor was shot and killed on campus Wednesday by a former student, who has since been arrested, authorities said.

Arizona state troopers stopped Murad Dervish, 46, in a vehicle roughly 120 miles northwest of the Tucson campus, just a few hours after the shooting.

Officers were on their way when they received reports of a shooting that left one person wounded and that the gunman had fled.

Firefighters transported the victim to the hospital, where he was pronounced dead.

There were no other injuries reported.University of Arizona Police Chief declined to identify him, but she confirmed he was a professor of hydrology. She did not know what the history was between Dervish, who used a handgun, and the professor.

The building where the shooting occurred is just northwest of the university bookstore and student union.

Campus alerts instructed people to stay away from the area, which was under lockdown.

Classes, activities and other campus events were canceled for the rest of the day. Classes will resume Thursday. But the building where the shooting happened may remain closed.
