Elizabeth Boshardy, 29, was crossing the street near downtown Chicago earlier this week when the truck driver made a left turn and reportedly didn’t see her in the crosswalk.
She was pinned under the truck; emergency crews removed her from the scene.
The pregnant woman, who was a data scientist who had degrees from the University of Illinois and the University of Chicago, later died at a Chicago hospital Tuesday, as Chicago Sun-Times reported.
Doctors were able to deliver the baby, as WGN reported.
The baby girl had been in a neonatal intensive care unit.
The Cook County medical examiner’s office announced that the baby died Saturday morning.
The truck driver, a 67-year-old suburban man, the Sun-Times reported, received a citation for failing to yield to a pedestrian in a crosswalk, police said.
