NORLINA, N.C. — North Carolina police say a man wanted for killing his son and critically wounding his ex-wife before using Facebook to admit to the attack has been found dead in a South Carolina motel room.

Norlina Police Chief Taylor Bartholomew tells media outlets in Raleigh, North Carolina, that law enforcers tracked Earl Valentine’s cellphone to Richmond, Virginia, on Wednesday morning. Bartholomew says Valentine was visiting his father’s grave.

The chief says police then tracked Valentine to Columbia, South Carolina, where U.S. Marshals found him dead from a self-inflicted gunshot wound.

Valentine was charged with murder in the shooting of his 15-year-old son early Tuesday. Police say the teenager was killed when he tried to stop Valentine from shooting Keisha Valentine.

Bartholomew says Keisha Valentine remains in critical condition.
