LOS ANGELES, June 18 (Xinhua) -- Authorities said Friday that a teenager was charged after going on a shooting spree that left one dead and 12 others wounded Thursday in the Phoenix metropolitan area in the U.S. state of Arizona.
Ashin Tricarico, 19, was charged with one count of first-degree murder, multiple counts of aggravated assault and drive-by shooting, and endangerment, according to the Peoria Police Department that led the investigation.
The male suspect, of the city of Surprise, Arizona, was booked into the Maricopa County Jail Friday morning, the department said in a release.
The release said that the motive of the suspect "is still unknown at this point as detectives are still sorting through evidence to determine exactly what occurred."
The shootings happened Thursday afternoon at eight locations throughout the West Valley cities, including Peoria, in the Phoenix metropolitan area and lasted more than one and a half hours.
Police said Thursday that the suspect was later found during a traffic stop in Surprise, where the suspect surrendered to policemen without incident.
Both Peoria and Surprise are major suburbs of Phoenix. The two cities are 15 km apart.
The victims range in age from 19 to 56 and are males and females of various races. The victim is a 56-year-old male, the Peoria Police Department said.
