A student at Indiana’s Purdue University has been killed in the nation’s latest campus shooting. Purdue University Police Chief John Cox said a suspect was in custody after carrying out what appeared to be a targeted attack.

John Cox: “This individual seemed to have had intentions for the decedent and took the action the individual took and then turned around and left the building and was taken into custody outside of the Electrical Engineering Building moments after the act by a West Lafayette city police officer that was arriving to assist.”

The shooting is at least the fourth at a U.S. school in the past week. Last week, five students were shot at middle schools and high schools in Philadelphia, Albany and Roswell, New Mexico.
