CENTRAL — The Central-Clemson community is still reeling from what police say was a drug-related home invasion, robbery and murder that claimed the life of a Clemson University student on Saturday.

The Pickens County Sheriff’s Office has made three arrests in the case, but a fourth suspect is sAtill at large and considered armed and dangerous, according to officers.

Warrants have been issued for the arrest of Lester Devaria Mosley, Jr., 18, of 312 Watkins St. in Central. Anyone with information on Mosley’s whereabouts is asked to call the sheriff’s office at 898-5500.

According to Pickens County Coroner Kandy Kelley, Steven Gregory Grich, 23, of Fort Mill, was pronounced dead from a gunshot wound at the scene of the crime, which occurred around 8:30 p.m. at the Chimney Ridge neighborhood complex in Central. Grich was a sophomore electrical engineering major at Clemson University.

On Monday, the PCSO announced that three suspects have been arrested, with all three charged with murder, armed robbery, first-degree burglary and possession of a weapon during a violent crime.

According to officers, information developed early Monday morning led investigators to charge Bernard Kadeem Ramsey, 19, of 923 Madden Bridge Rd. in Central.

Subsequent investigation implicated Mosley and brothers Jordan Charles Dalton, 19, of 218 Winchester Dr. in Central, and Jaron Bradley Dalton, 24, of 287 Belle Shoals Rd. in Six Mile.

Both Dalton brothers voluntarily went to the law enforcement center around 5 p.m. Monday to speak with investigators, and a black Dodge Durango seen on surveillance videos was located and impounded.

Officers said the motive for the crime appeared to be robbing Grich’s roommate of what was believed to be a large amount of marijuana, but only a few grams were actually taken.

The roomate, Robert Benjamin McKinley, was arrested Sunday and charged with simple possession of marijuana.

Sheriff’s office detectives have been assisted on the case by investigators from the Clemson University Police Department and the Clemson Police Department.
