HILTON HEAD ISLAND, S.C. AP – A business executive questioned by investigators in a couple’s disappearance apparently committed suicide by slashing his inner thigh with a knife, the Beaufort County sheriff said Thursday.

Sheriff P.J. Tanner told reporters Dennis Ray Gerwing had been dead for several hours before investigators identified him as a person of interest in the case Tuesday. Gerwing’s lawyer found his body in a condominium on this tiny resort island about 90 minutes after the sheriff’s office made his name public.
