An autopsy has determined that a 13-year-old Detroit boy who was abducted and killed this week was not shot to death.

The Wayne County medical examiner's office conducted an autopsy Friday. County spokesman Lloyd Jackson said in a statement that the manner and cause of Deontae Mitchell's death has yet to be determined, pending further investigation, but that the teenager was not shot.

Deontae had been riding his bike with a cousin Tuesday night when he was abducted outside a market on the city's east side. Surveillance video shows a man forcing the boy into a car.

Police believe that man was 45-year-old Gregory Walker, who was arrested Thursday with a woman in Toledo, Ohio. Deontae's body was found Thursday in a vacant lot on Detroit's east side.
