The Mercer County coroner ruled the boy's death an accident on Sunday, the Pittsburgh Post-Gazette reported. The results of the investigation will be given to Mercer County District Attorney Robert G. Kochems, Hermick said. A message left with Kochems was not immediately returned Sunday.
Hermick said the father was very distraught and cooperative; he said he doubts there will be charges, but that it's up to the district attorney. The father could face charges, including involuntary manslaughter, Hermick said.
