LITTLE ROCK, Ark. (KTHV) – Additional details were released on Thursday in a home explosion that killed a toddler in Paris, Arkansas last week.

The investigation and autopsy revealed that two-year-old Ryatt Reese was already dead at the time of the explosion.

Detectives say his mother's boyfriend, 27-year-old Ricky Carter admitted to pulling the boy's feet out from under him, making him hit his head.

Carter claims he tried to revive Reese, but when the boy died, Carter set off a gas explosion to cover it up.

Three other children were in the house at the time, but they made it out safely.

Carter is charged with first degree murder and arson.
