A judge has denied bond for a fourth man arrested in the investigation of the murder December 8 of Clemson student Steven Grich. Authorities say Lester Devaria Mosley Jr., 18, of Central was arrested Friday evening at a motel in Toccoa, Georgia. According to WNEG in Toccoa, Sheriff Randy Shirley of Stephens County learned, through contact by the Pickens County Sheriff’s Department, that Mosley might be in Stephens County. Shirley said once so advised, the Budget Inn on W. Currahee Street was placed under surveillance. Authorities say they confirmed the suspect’s vehicle location and a motel room that he was possibly located in. Shirley called Mosley the “trigger man” in Grich’s death. Two other men were arrested as officers carried out a search warrant. Shirley said Travis-Malik Shavon Campbell, 18, of Clemson and Marticus Gibson, 20, of Martin, Georgia were charged with hindering an apprehension.
