County medical examiners have determined that 4-year-old Christopher Acers died as a result of the fire at his Celia Avenue home Saturday, Hernando County Sheriff's spokesman Lt. Joseph Paez said.
Paez said Monday's autopsy indicated there was "no foul play."
Dispatchers received the call shortly before 7 a.m. Saturday. Three of the four occupants at 18005 Celia Ave. were able to escape . James and Kevin Crowley escaped without major injury. Jennifer Howard, Acers' mother, suffered serious burns and was flown to Tampa General Hospital, a sheriff's report said.
