The mother of a teenager has told authorities she believes her son killed 16-year-old Ryan Roberts.

ABC 13 talked to the mother of the friend who Ryan's mother claims killer her son. She told reporters that she "didn't raise him like that" and that her son had killed the family pets and started worshiping Satan.

"He doesn't believe in God, he believes in the devil," she said.

Roberts' mother was very upset because his "friend" had stayed under their roof on many occasions.

The alleged killer's mother signed the teen into a psychiatric ward and feels terrible her son did such a terrible act. She expects her son to be arrested at any time, although authorities have not commented or named anyone in the case at this time.
