(AP) -- A lawyer for a man serving a life sentence for killing a Horry County couple says he deserves a new trial because a prisoner says a witness lied.
The Sun News of Myrtle Beach reports at a hearing Wednesday, defense attorney Bill Grammer said he got a letter from a man on federal death row who was in jail with a key witness at 35-year-old Richard Gagnon's trial.
Gagnon was convicted in March of killing Diane and Charlie Parker Sr. Grammer says Chadrick Fulks told him he watched on television as Robert Mullins testified at Gagnon's trial and realized Mullins was lying based on things they talked about in the Horry County jail.
Fulks was sentenced to death for killing a woman kidnapped from a Conway store parking lot in 2002 whose body has never been found.
Prosecutors doubt Fulks is telling the truth.
