Authorities in Arizona arrested three teenagers in what they called a "copycat" case that mimicked a string of shootings and other attacks in the Phoenix area over the last two weeks.
The three 18-year-olds allegedly used slingshots to shoot granite rocks at pedestrians and vehicles, Maricopa County Sheriff Joe Arpaio and Arizona Department of Public Safety Director Frank Milstead said at a news conference Sunday afternoon.
Arpaio said the teens admitted to shooting at six pedestrians at State Route 24 and Ellsworth Road within four hours on Saturday.
Among the victims was a couple whose car window shattered from the rocks, he said.
