Authorities have identified an Augusta surgeon as being among five people killed in the crash of a private jet in eastern Georgia.

McDuffie County Coroner Foster Wiley said Thursday that Dr. Steven Roth, a vascular surgeon who worked for a medical practice called the Vein Guys, died in the crash Wednesday.

Two of Roth's co-workers — Lisa Volpitto and Kim Davidson — were also identified among the dead. Dr. Stephen Davis of the practice's clinic in Nashville, Tenn., says Volpitto was a nurse anesthetist and Davidson worked as a secretary.

Wiley early Friday identified Tiffany Porter as the fourth person killed in the crash.

He said one other person who died has not yet been identified.

Investigators say the jet aborted its landing and struck a 60-foot utility pole.
