2nd arrest made in Hilton Head robbery

A second Hilton Head Island man was arrested Sunday in connection with an armed robbery at an apartment complex June 14, and a third suspect is being sought.

William Joseph Barnes, 36, was charged with the armed robbery of an 18-year-old man at Hilton Head Gardens, according to a Beaufort County Sheriff's Office news release.

Rocky Dieblo Gadson, 30, was arrested immediately after the incident on charges of armed robbery and possessing a firearm while committing a violent crime.

Investigators are now searching for 23-year-old Marcus Jamel Johnson, who is wanted on the same charges, the release said.

The victim reported he went to the apartment with Barnes to move some belongings. Barnes then left him alone, and Gadson and Johnson entered and held him at gunpoint, a release said. No injuries were reported.

Johnson is about 6-foot-1, 145 pounds. His last known address is Southwood Park Drive on Hilton Head.

Anyone with information about Johnson's whereabouts should call Investigator J. Adams at 843-255-3415 or the county Dispatch Center at 843-524-2777.
