PHOENIX — A truck's passenger window shattered on a Phoenix freeway Wednesday as Arizona authorities investigated a string of highway shootings that have rattled nerves and heightened fears of a possible serial shooter.

The state Department of Public Safety has not yet confirmed whether the glass was shot out. Nobody was hurt, agency spokesman Bart Graves said.

Authorities were already investigating nine shootings of vehicles over the past two weeks. Four cars were hit last week along the city's main freeway. One bullet shattered a windshield, and the broken glass cut a 13-year-old girl. The other rounds hit a headlight and the sides of vehicles.

Then on Tuesday, police announced that they were investigating five more shootings, including one that shattered the window of an off-duty police sergeant's vehicle as he drove to work. On Wednesday, investigators raced to a gas station after the driver of a white truck pulled off Interstate 10 with a shattered window.

Department of Public Safety Director Frank Milstead called the incidents “domestic terrorism crimes.”

“Anytime that you have multiple shootings against American citizens on a highway, that's terrorism,” Milstead said. “They're trying to frighten or kill somebody.”
