A driver was charged in connection with the hit-and-run crash that left a mother and her unborn baby dead Sunday night.

On Tuesday, Waukegan police charged 49-year-old Rosalinda Vaca, 49, of Waukegan, with felony leaving the scene of an accident. 

The Lake County Coroner's Office said 36-year-old Michelle Heidbrick was crossing the street in front of the BP gas station at Grand Avenue and Jackson Street on Sunday shortly after 9:30 p.m. when she was struck by a car.

Police said she was critically injured and taken to Vista Medical Center East, where she was pronounced dead.

The vehicle sped off from the scene of the crash before police could get there, the coroner's office said.

The coroner said Heidbrick died from blunt force trauma from the crash and confirmed she was pregnant and in her second trimester when she was killed. The coroner said the fetus also did not survive.

Police said Vaca told them that she was driving a black 2016 Land Rover SUV at the time of the crash. She mentioned that she struck something in the roadway, but didn't realize what it was.

Vaca learned about the report of the deadly crash and decided to turn herself in after realizing she was involved in the crash, police said.

Police said the vehicle was found and is being held for ongoing investigation.
