Mississippi police say they’ve located the vehicle of a nonverbal, autistic Louisiana teen, but the young man is still missing.

Noah Daigle, 19, went missing on Sept. 18, when he left his home in Ponchatoula, Louisiana. He was driving a white, 2001 Cadillac Eldorado. It was located on I-10 near the Mississippi-Alabama state line where it appears to have run out of gas.

Daigle was reportedly last seen wearing blue jean shorts and a black t-shirt. He has low cut brown hair, brown eyes, stands 5’8″ and weighs approx. 130 lbs.

Anyone who sees Daigle is asked not to approach him, but to call 911 or contact the Ponchatoula Police Department at 985-386-6548.
