Tasha Haefs allegedly called 911 Tuesday night telling authorities she believed the devil was trying to attack her. Officers then arrived at her home to check up on her and found blood on the front steps and could hear a woman singing. The officers found the body of the decapitated 6-year-old boy near the kitchen. They also found a decapitated dog in the basement. Haefs told police the boy was her biological son and admitted she killed him. She was charged with first-degree murder and armed criminal action.
