A New Jersey mother killed herself after decapitating her 2-year-old son just months after child welfare workers returned the boy to her. Chevonne Thomas lost her son, Zahree, after she was charged with child endangerment. But in spring she regained custody of the boy, whose head was discovered by police in Chevonne's freezer wrapped in plastic, reports AP. Cops came to the Camden home after Chevonne called 911 to tell a dispatcher about Zahree's death; she then fatally stabbed herself in the neck. (More parenting stories.)
