Madison police are trying to determine if gunfire shattered the window of a car on the west side on Sunday.
Officers were called to the 1300 block of Temkin Avenue at 9:23 p.m. for a report of gunshots. A car parked on the street was found to have a shattered window.
A witness told police he saw a van driving in the area and heard what he thought were rounds from a small-caliber handgun. Another witness told police children throwing rocks were to blame, but no other witnesses could substantiate that story.
No shell casings were found. The car was impounded by police for further investigation.
