Police: Man who killed son, wounded ex-wife found dead

A man wanted for killing his son and critically wounding his ex-wife before using Facebook to admit to the attack was found dead in a South Carolina motel room on Wednesday, North Carolina police said.

Norlina Police Chief Taylor Bartholomew told media outlets in Raleigh that authorities tracked Earl Valentine's cellphone to Richmond, Virginia, on Wednesday morning. Bartholomew said Valentine was visiting his father's grave.

The chief said 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 said the teenager was killed when he tried to stop Valentine from shooting Keisha Valentine.

Bartholomew said Keisha Valentine remains in critical condition.
