Authorities issued a Blue Alert on Thursday after a shooting involving an Arizona state trooper in a Phoenix residential area.
One suspect was in custody and another was at-large after the incident near 37th Avenue and Portland Street, Department of Public Safety Director Heston Silbert said during a press conference.
Around 9 a.m., a teenage male got out of a car and fired multiple shots with an AK-47 assault rifle at a DPS detective in a vehicle, who returned fire, Silbert said.
The suspected shooter, identified as 17-year-old Luis German Espinoza Acuna, was taken into custody and the weapon was seized, but the search for the driver, believed to be a Hispanic male in his late teens, continues. No injuries were reported.
“There was no question, it was an ambush,” Silbert said.
