Bradley Kenneth Simons, 22, of High Chaparral Drive, was walking on Old Evans Road near Dent Street when he was struck about 3:36 a.m., Columbia County sheriff’s Capt. Steve Morris said.
A passer-by saw Simons face down in the westbound lane and stopped to help. She told deputies that she tried to flag down a four-door Jeep Wrangler, but it ran over Simons and continued heading west on Old Evans Road.
Simons was taken to Georgia Regents Medical Center where he was in critical condition Sunday afternoon, spokeswoman Jennifer Scott said.
