A MAN is on the run after killing his 15-year-old son, critically wounding his ex-wife and then confessing to the horrific attack in a Facebook Live video.

Earl Valentine allegedly kicked in the back door to Keisha Valentine’s home in the US state of North Carolina before shooting her and their son Earl Jr in the chest at point-blank range.

Valentine posted a video on his Facebook page after the Tuesday morning assault admitting to his ex-wife’s shooting, Norlina police chief Taylor Bartholomew said.

“She lied on me, had warrants taken out on me. She drug me all the way down to nothing,” Valentine said in the video. “I loved my wife, but she deserved what she had coming.”

The post has since been removed. The chief said a domestic protection order was in place but expired last month.

“We got a got at 1.30 in the morning from the victim giving a dying declaration that his father shot him and that his father had shot his mother as well,” Bartholomew told WTVR.

“It appeared that the son tried to intervene on his mum’s behalf and he was shot one time in the chest as well.”

Bartholomew said officers are hunting Valentine after he indicated that he was on his way to Richmond, Virginia, to kill other family members. The fugitive’s relatives have been put under police protection.

Valentine, who runs a limo service, is facing a first-degree murder charge in his son’s death.

The FBI Fugitive Task Force and US Marshals are involved in the manhunt.
