A deadly shooting spree on Saturday that started in Chicago and ended in a shootout in nearby Evanston left at least four people dead, including the person thought to be the gunman, and at least four others critically wounded.

The suspect was killed in a shootout with Evanston police officers after a rampage that targeted seemingly random victims, including a 15-year-old girl shot in the head while riding in a car with her mother and a woman who was taken hostage in a restaurant before being shot by her captor. The girl is critical.

Among the dead were a building security guard and a man, believed to be a University of Chicago student, whose body was found in a parked car.

Chicago police superintendent David Brown identified the suspect as Jason Nightengale, 32, of Chicago.
Brown said that the investigation was still in the preliminary stage and did not comment on a possible motive.

Two women aged 77 and 80 are among those critically injured.
