LIST: Where the confirmed shootings have happened
State troopers have responded to several reports of broken windshields since them, but most have been determined to be caused by road debris and not connected to the larger freeway investigation.
DPS has placed 16 digital billboards advertising the case and the $50,000 reward along the freeways and passed out thousands of fliers to nearby neighborhoods hoping to reach those who may not be following media coverage.
Arizona Department of Transportation has also placed the DPS Tip Line phone number on all of its electronic signs.
Friday evening's incident is still under investigation.
