Human remains discovered 31 years ago in Indiana have been identified as a man from South Carolina. Authorities say relatives of Michael Benjamin Davis had lost contact with him in the late 1980s. Remains were found in 1993 at what is now a golf course in Greenwood, Indiana, south of Indianapolis. The Johnson County coroner says Davis' cause of death hasn't been determined, but the case has long been considered a homicide. Davis was born in Richland County, South Carolina, in 1965. His family plans to speak to reporters Thursday in Indiana.
