A third suspect has been charged with murder in connection with a 2010 home invasion in McClellanville that resulted in two deaths.

Sheriff's investigators arrested Jeremiah Belton, 40, of North Charleston on Sunday and charged him with one count of murder, first-degree burglary and possession of a firearm during the commission of a violent crime.

On July 10, 2010, a group of men pretending to be FBI agents busted into a home on Old Georgetown Road, according to authorities. During the home invasion, shots were fired by both the intruders and residents.

One of the home's occupants, Melvin Simmons Jr., 35, was killed in his bedroom, investigators said.

Curtis Darnell Delaney, 26, of North Charleston also was found dead. Investigators believe he was one of the intruders and was hit when someone inside the house grabbed a gun and started firing.

Authorities were led to their first suspect, Troy Mason, 25, who they charged with murder, by analyzing DNA of blood left at the scene, officials said.

Mason then led investigators to a second suspect, Mario Caldwell, 35, of Charleston in 2012. Caldwell, who was also charged with murder, then told investigators about the involvement of the third and recent suspect to be arrested, Belton, according to authorities.

Mason's murder charge remains pending.

Caldwell was charged with murder but pleaded guilty to voluntary manslaughter in May. He has not yet been sentenced.

A magistrate could not set bail Monday afternoon. Only Circuit judges can set bail on murder charges.
