The woman above kidnapped her son from his father, who had primary custody of him after storming his home with two armed thugs.
She later posted a video on Facebook showing her beating and strangling the child while she uttered profanities. The boy could be heard pleading for help as his deranged mother battered him.
She then asked her ex for a ransom if he wanted the child back. The Brazilian police have launched a full on manhunt for the woman.
