Fonnezle Delane, 30, has been sentenced to life in prison in connection with the murders of Talya Poston and Billy Hall, Jr.
Hall and Poston were found shot to death on Isaiah Road in Florence County in September 2009.
Delane pleaded guilty to two counts of Accessory Before the Fact of Murder, Monday.
Delane hired two hit men to kill the couple because Hall was a witness against Delane in a pending drug case.
If convicted in that case, Delane faced 15 years in prison and prosecutors say he didn't want to go to prison.
During Tuesday's sentencing hearing, Delane's mother fell to the floor and was unresponsive.
The hearing stopped for about 20 minutes. Delane told the court his mother suffers from a medical condition that may have caused her to collapse. She left the court room on a stretcher.
Delane apologized for the murders saying he's had four years to reflect on what happened. He says he's a stronger man.
The victims' families asked for Delane to get the maximum sentence, saying he took the lives of their loved ones and deserved to sit in prison for the rest of his life.
Three others pleaded guilty to the crimes and will be sentenced at a later time.
