PATUXENT RIVER, Md. (AP) — Navy officials say a 17-month-old boy was found dead in a vehicle at a naval station in southern Maryland.

Public affairs officer Connie Hempel said in a news release that the child was found unresponsive in the back of a vehicle about 3:30 p.m. Wednesday at Naval Air Station Patuxent River. Hempel said emergency workers from the station performed CPR but the boy was pronounced dead at 4:15 p.m.

The Naval Criminal Investigative Service is investigating. NCIS spokesman Ed Buice said in an email late Wednesday that the boy was left in his car by his father, who works at the base. Buice did not know how long the child had been in the vehicle.
