Kelvin O'Neal, 26, of Darlington, was sentenced to 12 years in prison last week after he pleaded guilty to Accessory After the Fact to Murder and Possession with Intent to Distribute Cocaine in connection with the murders of Talya Poston and Billy L. Hall Jr.
Poston, 32, and Hall, 26, were found shot to death on Isaiah Road in Florence County in September 2009.
O'Neal was the last of five men sentenced for the murder for hire crime.
Fonnezle Delaine wanted the two dead because they were set to testify against him in his drug trial. The victims' testimony could have put Delaine away for more than 20 years.
Delaine orchestrated the killings and hired two people to kill Poston and Hall. He is serving a life sentence.
Twelfth Circuit Solicitor Ed Clements said on the orders of Delaine, O'Neal got drugs and money to pay the shooters for their work following the murders.
O'Neal has to serve at least 85% of his sentence before he's eligible for parole.
