A 5-year-old boy remained in critical condition Monday after police said his mother took a kitchen knife to his throat.

Daphne Spurlock, 45, told Magnolia, Texas police she slashed her son’s throat because “he was infested with demons.” On Saturday night Spurlock stomped on her son’s head and chest before slitting his throat.

The child’s father came home from work to find Spurlock standing over the child.

The young boy was air-lifted to Memorial Hermann Hospital after his father called 911. His mother has confessed and is in Montgomery County Jail on attempted capital murder charges.
