The pedestrian, Beverly Akerson, 43, died eight hours later.

Two witnesses saw the car speed down westbound Lawrence Avenue around 1:30 a.m. Saturday, police said.

When the woman was hit by the car, she landed motionless on the ground, Town Hall District police Lt. Jeffrey Hoffmann said. Witnesses told police after hitting the woman, the driver of the car reversed and hit her again while she was laying in the street.

“It was cold,” Hoffmann said of the driver’s actions.

Akerson was pronounced dead at 9:58 a.m. at Advocate Illinois Masonic Medical Center, according to the medical examiner’s office.

No one saw the license plate on the car, which was possibly a Buick. The car is described as a 4-door light-colored sedan. It was last seen heading south on Sheridan. Police say it’s possible the vehicle has damage to its front end.

According to police, at this time there is no indication that the driver of the car knew the woman.

Anyone with information on the crash is asked to call the police Major Accident Investigation Unit at (312) 745-4521.

The Uptown hit-and-run was among numerous crashes in the city and suburbs over the weekend, which left a total of four people dead and two more critically injured.
