MOON TOWNSHIP, Pa. -- A father is behind bars accused of leaving his three young children home alone.

Police said Chad Victor Braun left his three children alone inside a Moon Township home. Investigators said the children, ages 1, 3 and 4, were living in horrible conditions.

On March 21, police were called to the home on Oak Drive. A Children Youth and Families worker made an unannounced visit. No one answered the door, but she heard children inside.

According to the criminal complaint the kids were home alone, naked and had severe redness and irritation on their bodies. The children were reportedly eating uncooked frozen french fries.

Moon Police Chief Leo McCarthy said, “Horrendously filthy, horrendously filthy; mattresses overturned, filthy. The sink completely piled with dishes and stuff. There's one toilet in the house and it was nonfunctional.”

Police also found two pieces of rubber tubing tied around both bedroom doors. Investigators believe it was put there to keep the children from getting in or out of the rooms.

The children were examined at Children's Hospital and diagnosed as being malnourished. One had ringworm.

Braun remains in the Allegheny County Jail, charged with three counts of child endangerment. His children are in foster care.
