The teenage boys were discovered after detectives spoke to one of their parents who said he had seen them out shooting the night of the incidents.
On Feb. 14 and Feb. 15, reports were made of several Wal-Mart tractor-trailers being struck by bullets on Highway 75, a press release by the Tulsa County Sheriff’s Office states.
While they were driving, drivers believed the loud noises were rocks hitting the rigs, which is common, however, upon arrival at their destination, drivers realized it was bullets not rocks that hit them, the press release says.
Authorities began canvassing the area while Wal-Mart asked its drivers to make a detour and not drive on Highway 75, according to authorities.
