Court documents read that the father admitted he left the handgun on top of a gun safe, saying that the gun is always loaded with a live round in the chamber.

The mother says all four children were staying in a first floor bedroom because the second floor of the home had no electricity.

The children moved to the master bedroom where the gun was located, when the electricity stopped working on the second floor.

Police found multiple safes and trigger locks in the home, none of them being used.
