TULSA, Oklahoma - Tulsa Police are looking for the person who shot a passenger in a car headed west on Interstate 44 Monday night.

Police said the victim was intoxicated after celebrating his birthday. He didn't realize he'd been shot until he arrived home with his brother and friend and discovered the pain in his left shoulder was actually a gunshot wound.  

They called police who found two bullet holes in the car he'd been riding in, one in the rear window and the other in the trunk.  

The victim was taken to a Tulsa hospital to be treated for the wound. Doctors located a second gunshot wound with a bullet lodged in the victim's buttocks.

The victim and the two others in the car told officers they heard multiple "popping" noises while driving on I-44 and saw a maroon Toyota Camry exit at Highway 75.

Police said the victim was not seriously injured.
