The Arizona Department of Public Safety has determined that a vehicle that had a window broken on Interstate 10 Wednesday morning was not hit by a bullet.
The driver of a Pontiac Grand Am was heading west on I-10 around 43rd Avenue when he heard something hit his left rear window at about 3:30 a.m.
"I just heard a big bang and then heard that my window shattered," Brandon Waters said.
Waters said he followed what he is calling a suspicious vehicle for a number of miles and then lost track of it but managed to get the license plate number.
He pulled over at I-10 and Dysart Road to talk to DPS.
Investigators later confirmed that the window was broken by road debris and the incident is not related to the string of freeway shootings.
DPS said there have been 11 confirmed shootings, mostly along I-10, since Aug. 29.
Phoenix police officers will be going door to door Wednesday to pass out fliers to help DPS get more tips. The fliers contain information about a $50,000 reward and details about the shootings.
Anyone with information is asked to call the tip line at 602-644-5805.
