Authorities stand near debris left from an overnight plane crash near Hancock County roads 18 and 216. Authorities are still trying to identify one of two people killed in a weekend plane crash. The identified body was that of Ralf Bronnenmeier, CEO of Grob Systems in Bluffton, who was piloting the single-engine plane. A coroner was trying to identify the remains of a woman killed in the crash, but the Hancock County Sheriff's Office says DNA testing may be needed. Authorities say the Federal Aviation Administration and National Transportation Safety Board have launched investigations.
