A victim of an assault on New Year's Eve in Jessamine County has died, and new charges might be filed, Jessamine Chief Deputy Sheriff Allen Peel said Thursday.

James Dean Wallace, 32, of Lexington was a passenger in a vehicle driven by Curtis L. Flora, 36, of Lexington when the two men got into an argument while driving on Vince Road in Jessamine County about 7:30 p.m. Monday, authorities said.

Flora allegedly beat Wallace, "striking him multiple times in the head with a closed fist," before driving him to a residence in Lexington later Monday night, according to a sheriff's office news release.

A bystander at the residence called 911, and Wallace was taken to the University of Kentucky Chandler Hospital with what proved to "unsurvivable" injuries, the Fayette County coroner's office said.

Wallace was pronouced dead at 10:18 a.m. Wednesday, according to the coroner. The cause of death was traumatic brain injury resulting from blunt force injuries to the head.

Flora was being held in the Jessamine County jail on a charge of first-degree assault. He declined comment Thursday through jail officials.

Peel said prosecutors had been notified of Wallace's death and that additional charges probably would be addressed at a preliminary hearing in Jessamine District Court at 2 p.m. Monday.
