LEXINGTON, S.C. – Lexington County deputies are asking for the public’s help as they work to find a Gaston man accused of shooting a man to death at a party June 25.

Keyshaun Alfred Muller, 19, is charged with murder, assault and battery of a high and aggravated nature, and possession of a weapon during a violent crime, according to arrest warrants.

“Investigators have been looking for Muller since we obtained arrest warrants on him late last week,” Lexington County Sheriff Jay Koon said. “We need help from the community to locate and arrest him. Someone knows where he is and can put us right on his trail.”

Muller shot and killed Trayon Newhouse after they argued in front of a house on Minolta Drive, according to Koon. Detectives said Newhouse was not armed nor did he provoke Muller before the shooting, which also injured a child.

“We know some people might be uneasy about helping us find and arrest Muller,” Koon said. “I can assure everyone that sharing tips through Crimestoppers is always anonymous.
