(TUCSON, AZ) -- A professor was shot and killed on the University of Arizona campus in Tucson on Wednesday afternoon, allegedly by a former student, campus police said.
The suspect, Murad Dervish, 46, was taken into custody hours later following a traffic stop by the state’s Department of Public Safety near the town of Gila Bend, University of Arizona Police Chief Paula Balafas said at a news conference.
The victim was identified Thursday as professor Thomas Meixner, department head of the Department of Hydrology and Atmospheric Sciences, said university president Robert Robbins.
"This incident is a deep shock to our community, and it is a tragedy. I have no words that can undo it, but I grieve with you for the loss, and I am pained especially for Tom’s family members, colleagues and students," Robbins said.
