One person is dead and a dozen people injured after an apparent drive-by shooting spree near Phoenix, authorities said.
Police are investigating at least eight different shooting incidents that occurred over the course of a 90-minute period Thursday morning throughout the West Valley, according to Sgt. Brandon Sheffert, a spokesperson for the Peoria Police Department, which is leading the investigation.
"This is an extremely complex investigation," Sheffert said during a press briefing, noting that multiple agencies are involved, including several police departments and the FBI. The number of shooting sites "could obviously grow," he said.
The Bureau of Alcohol, Tobacco, Firearms and Explosives told ABC News it is working to match ballistic shell casings from the various shooting scenes and tracing the recovered gun to figure out where the shooter bought or obtained the gun. It will also search the suspect's home for any other weapons.
