FORT LAUDERDALE, Fla. (AP) - Authorities in Broward County are investigating the death of a 4-year-old boy who was pulled from a hot day care vehicle where he had been left alone.

The Broward Sheriff's Office says Jordan Coleman was found unconscious in the vehicle Wednesday afternoon with temperatures in the low 90s. Attempts to revive the boy failed, and he was pronounced dead a short time later.

The vehicle belonged to the 3C's Day Academy in Sunrise. BSO's Child Protective Investigations Section is investigating the boy's death and the safety of other children at the day care center. Authorities say the center is now closed.

An autopsy was done Thursday on the boy's body but the results have not yet been announced. No one has been charged in the case.
