UPDATE: Tuesday @ 6 p.m.
SCIOTO COUNTY, Ohio (WSAZ) -- While it seems like common sense, locking guns and bullets away from kids is vitally important.
That rule of thumb was broken once again Monday. A 2-year-old boy was shot and killed by his 8-year-old brother. But just who was responsible?
Investigators on Tuesday showed us the 20-gauge shotgun that killed 2-year-old Austin Burchett. They said a grandparent was watching four young brothers in a rural Scioto County mobile home Monday afternoon while the parents went out for cigarettes.
While the grandparent was playing a video game with some of the kids in one room, the 8 year old got the gun in a back room and shot it, grazing his 3-year-old brother and killing Austin.
"The 8 year old did not seem to understand," Scioto County Sheriff's Capt. David Hall said. "Maybe he's in shock; it's a bad situation."
The boy's aunt said the 8-year-old shooter is mentally challenged. A great uncle said the shotgun was hidden under three mattresses, and the adults thought the shells were all out of the trailer, but at least one was not.
"We don't know where he got the shell -- somewhere inside the trailer," Hall said.
He said prosecutors will present suggested charges of child neglect against the parents to a grand jury -- neglect also stemming from what investigators said were the unlivable conditions inside the home, including exposed electrical wires and dog feces.
About two weeks ago, a Jackson County, Ohio, 4-year-old boy loaded and fired a shotgun -- wounding a teenage babysitter. Hall said both incidents were highly preventable.
"They have responsibility," Hall said of the adults in both cases. "We have gun locks."
Gun locks usually are provided free of charge. Meanwhile, Scioto County Children's services officials removed the surviving brothers from the parents' home. They are staying with other family members.
Family member tell WSAZ.com that they thought the shells were separated from the gun and out of the house.
Monday night, deputies say the 8-year-old shot his 2-year-old brother, killing him. Another brother, a 3-year-old, was also shot, but only had minor injuries.
The Scioto County Sheriff’s Office says the parents were not home at the time of the shooting -- they had gone out to get cigarettes. One of the children’s grandparents was in the trailer at the time of the shooting.
The sheriff’s office does not plan to release the name of the victim or family members involved in the incident, but the 2-year-old's great uncle who lives next door tells WSAZ.com the boy's name was Austin Burchett.
Prosecutors say they plan to recommend charges of child neglect against the parents. They say the neglect is due to what they call “unlivable conditions” in the trailer.
There were four children in the trailer at the time of the shooting and all have been removed from the home. They are currently staying with family members.
The incident happened about 4 p.m. Monday inside a home in the 2000 block of Kinker Road in Minford. When EMS workers arrived at the home, they found the younger child dead. They also found a 3-year-old boy who had been shot in the arm. The 3-year-old child is another sibling.
He was taken to Southern Ohio Medical Center in Portsmouth where he was later released for pellet wounds. The names of the children haven't been released, but the children have been removed from the residence by Scioto County Children's Services due to the nature of their living arrangements.
911 dispatchers are not releasing much information, but tell WSAZ.com that it happened in the Minford area.
No word yet how seriously anyone was hurt.
