Kansas City woman decapitated her 6-year-old son, authorities say

A Kansas City woman who authorities said decapitated her 6-year-old son was charged Wednesday with first-degree murder, the Jackson County Prosecutor's office said.

Tasha Haefs, 35, was charged after officers found her son dead at their east Kansas City home late Tuesday, according to a probable cause statement. It was not immediately known if Haefs had an attorney to speak on her behalf.

Police said in an affidavit for a search warrant that a woman called from the house and said the devil was trying to attack her before she hung up, CBS affiliate KCTV reported.
