Three cars were hit by thrown rocks, two of those along a stretch of I-10 near Sunset, according to the Arizona Department of Public Safety.
Annelise Brokaw says she left work Monday and was driving on I-10 near Sunset when suddenly her windshield was hit out of nowhere.
"I heard a big pop and glass kind of flew at me so I immediately pulled over and called 911 because I was not sure what happened and someone threw a rock through my windshield," she said.
Arizona DPS's Quentin Mehr says the day before Brokaw's incident two other cars on I-10 were struck with a rock.
One happened around 7:30 a.m. near Craycroft and the next happening around 2 p.m. west of milepost 251.
"The other two victims the rock had actually gone in their side windows and shattered completely and a rock was found in the car so they were able to get fingerprints on that rock," Brokaw said.
Mehr says if caught, some of the charges a person could face are assault, criminal damage, and endangerment.
