JACKSONVILLE, Fla. -- A 16-year-old boy was run over by a car while he slept as he waited for a school bus early Friday morning on the Westside.

According to police, the teenager apparently was sleeping in the 500 block of Towering Pines Drive and was lying in the street when he was hit by a vehicle about 6:30 a.m.

Police said the driver did not stop, possibly not knowing the boy was hit.

The boy was on the side of road waving for help when a passerby spotted him and called 911.

Jacksonville-Fire Rescue personnel responded and the boy transported to Shands-Jacksonville Medical Center. Police said the boy suffered head injuries, broken ribs and a broken leg -- serious but not life-threatening injuries.

"We're not certain what the thinking of this 16-year-old was, but clearly he was irresponsible by lying in the roadway -- from what I'm told with a blanket and pillow," Jacksonville Sheriff's Office spokesman Ken Jefferson said. "If you're going to rest and wait on the bus, get to the side of the road."

Traffic homicide investigators said there were no skid marks at the scene and no witnesses.

Channel 4's Adam Landau is learning more about the incident and the victim and will have full reports beginning at 5 p.m. on the local station.
