Two people have been charged with murder after their roommate was found "tied and restrained with Christmas light cords and tape" in a shallow grave near Reedy River, according to an arrest warrant.

The body was found Tuesday in an open field off Dunklin Bridge Road, according to Lt. Ryan Flood, with the Greenville County Sheriff's Office.

According to Flood, investigators discovered the body after receiving information just after 3 p.m.

Flood said Amanda Marie Scott, 36, and Denardis Jamont Kilgo, 39 are facing charges for murder and kidnapping after investigators learned the pair, who was staying with Jackson at the time, killed her using blunt force trauma, bound her and buried her in a shallow grave.

A warrant said Jackson "suffered blunt force trauma and was wrapped in a manner which prevented her from breathing, effectively obstructing her airway."

The motive for the killing is still under investigation, Flood said.

The body of Carolyn Jackson was found in a shallow grave about 5 miles from her Honea Path home on March 24, Greenville County deputies said.

Jackson was attacked by her roommates, Amanda Marie Scott and Denardis Jamont Kilgo on March 14. They tied her up with Christmas lights and tape and wrapped her in a way that restricted her breathing, according to arrest warrants.

Jackson died after being beaten, deputies said.

Investigators said they haven't determined why the pair killed Jackson.

Scott, 36, and Kilgo, 39, are charged with murder and kidnapping and remain in jail.
