A bloodthirsty North Carolina man who slayed his teenage son and critically wounded his ex-wife killed himself Wednesday evening, after livestreaming a chilling confession over Facebook, police said.

“What’s up everybody? I just killed my f—— wife,” Earl Valentine said in his early Tuesday admission video. “I loved my wife, but she deserved what she had coming.”

“I’ve been very sick for months and this is something that I could not help,” he added.

Less than 48 hours later, officers found Valentine in a Columbia, South Carolina motel room — dead from a self-inflicted gunshot wound. Investigators had previously tracked Valentine’s cellphone to Richmond, Virginia where he allegedly visited his father’s grave.

The ruthless killer broke into his ex-wife’s Nolita, North Carolina home early Tuesday and fired several shots, fatally striking his 15-year-old son as he tried to protect his mother.

Police believe Valentine didn’t intend to hit the teenager.

The ex-wife, Keisha Valentine, survived the grisly attack and remained in critical condition Wednesday evening. As Valentine fled the scene, his dying son used his last words to call police and report his father’s heinous crime.

Valentine also called police and told officers he was on his way to Virginia to kill more family members.

“When we spoke to him on the phone he told us he is basically armed and dangerous,” Norlina Police Chief Taylor Bartholomew.

Valentine recorded his haunting confession before driving away, police said. He mistakenly believed his ex was dead, and said he felt no regret for the slaying.

“She lied on me, had warrants taken out on me. She drug me all the way down to nothing,” he said in the video, which has since been removed from Facebook. “I don’t feel no remorse for what I did.”
