FLORIDA -- Carbon monoxide is being blamed for the deaths of five teens in a south Florida motel.

The teens were found in a room at this hotel in Hialeah Florida Monday Morning.

Police believe a car left running in a garage below the room is to blame for contaminating the room with carbon monoxide. 

Witnesses say the car needed a jump start earlier and was left on to recharge the battery. 

Investigators say no alcohol, illegal drugs or other suspicious items were found inside the room.
