LEXINGTON, S.C. -- Sheriff’s deputies are charging a South Carolina man already in jail with murder in the death of a victim whose body was found buried in a backyard grave.

Lexington County Sheriff James Metts says detectives served 41-year-old Richard Earl Barnes of West Columbia with a murder warrant. Barnes was already being held at the county jail in connection with the death of 54-year-old David Diblasi, who was killed in February.

Lexington County’s coroner determined Diblasi was stabbed in one eye and his neck and suffered a fractured skull.

Worth Cook of Leesville also is charged with murder and other crimes.

Metts says investigators allege that Barnes and Cook stabbed Diblasi multiple times at Cook’s home, then tried to use the victim’s bank card and credit card for purchases.
