THOMSON, Ga. (AP) -- A coroner has confirmed the identity of a fourth person who died when a business jet collided with a 60-foot utility pole and caught fire after aborting its landing at an east Georgia airport.

The plane was carrying a surgeon and members of his clinic staff when it went down Wednesday night at the Thomson-McDuffie Regional Airport after a flight from Nashville.

McDuffie County Coroner Foster Wiley said early Friday that identities of four people killed had been confirmed: Dr. Steven Roth, a vascular surgeon; nurse anesthetist Lisa Volpitto; secretary Kim Davidson; and Tiffany Porter.

Dr. Stephen Davis, a surgeon who works for an affiliated clinic, has said Porter and the fifth person killed were ultrasound technicians.

Wiley said dental records would be used in an attempt to positively identify the fifth person.
