CLEVELAND, Tenn. -- A 5-year-old Bradley County boy who was airlifted Thursday to Children's Hospital at Erlanger died there Friday, authorities said.

Bradley County Sheriff's Office spokesman Bob Gault said Leland Bates died Friday afternoon.

He said authorities are awaiting results of an autopsy of Leland's 3-year-old brother, River Bates, who died in an ambulance Thursday en route to SkyRidge Medical Center in Cleveland. The autopsy was scheduled for Friday, but Gault could not confirm the examination's status late in the day.

Investigators with the sheriff's criminal investigations division are trying to find out what happened to the children, he said.
