Authorities in Phoenix are investigating a report of another possible shooting of a vehicle in the same area where cars have been shot at over the last two weeks.

Department of Public Safety spokesman Bart Graves says no information is immediately known on the circumstances of what happened on Wednesday. Authorities are at the scene of a gas station where the vehicle apparently exited Interstate 10. Graves says nobody was injured.

Authorities were already investigating nine shootings of vehicles over the past two weeks that have heightened fears of a possible serial shooter on Phoenix-area freeways. Department of Public Safety Director Frank Milstead has called the incidents "domestic terrorism crimes."
