The children’s mother attempted to contact and locate the man and the children Sunday, to no avail.
Police were unable to get in contact with the man before visiting his home Monday and finding the three dead.
The man hanged himself, but police aren't yet saying how the children died, WXIN reported. According to KRON, there were no obvious signs of trauma or what caused the children's deaths.
The man and the children’s mother were married but separated for six months. The two were going through a divorce.
