Polston died of blunt force trauma in the crash, the coroner said in a release Wednesday.
Early information in the investigation suggested slick conditions might have been a factor, police said.
The accident happened near Bogart Lane. Officers responded to a rollover at 6:51 a.m. and found the vehicle in a canal. The car was headed westbound on State Street and veered off the right side of the road, police said.
