The suspect in this shooting was described as a man in his 30s with long brown or blonde hair. He had a mustache and goatee and was driving a dark gray or black newer sedan with light tinted windows.
The second shooting happened on the eastbound side near the Cactus Avenue and Ayala Drive exits. The driver sustained a gunshot wound to the lower arm and was hospitalized for the non-life-threatening injuries.
The suspect was described as a man between 40 to 50 years old with long dark hair up to his shoulders and a goatee. Police said he was driving an early 2000s dark gray sedan.
