Two women, ages 70 and 63, were among those injured in the crash.
Five people were injured Friday morning in a serious crash that sent a car careening into Calumet Heights flower shop on the South Side.
A Nissan Maxima occupied by three people in their 20s ran a stop sign and struck a Toyota Corolla about 7:30 a.m. at Stony Island Avenue and 87th Street, according to Chicago police.
After hitting the Corolla, the Toyota crashed into a flower shop and caught fire, police said.
Two women in the Corolla, ages 70 and 63, were injured in the crash and taken to the University of Chicago Medical Center. Police initially described their injuries as being grave, and later said they were not considered life-threatening.
The driver of the Nissan, a 27-year-old man, was pulled from the car and taken to the University of Chicago Medical Center in good condition, according to police. Two other people in the car were also taken to a hospital, where they were in serious condition, according to Chicago fire spokesman Larry Merritt.
