A coroner says Wyatt drowned Sept. 5 in the septic tank on his family's property in Greene Township, about 25 miles northwest of Pittsburgh. But authorities have yet to rule whether the boy accidentally fell into the tank or whether his death was the result of criminal negligence or some other crime.
The boy was playing with two young sisters when he went missing, prompting an 18-hour search.
A prosecutor says it's possible the boy removed the tank's 14-pound lid by himself before he wound up in the tank.
