Police in Chicago shot and killed a gunman Saturday after exchanging gunfire and after the gunman had killed three people and injured five in a shooting spree in the city's southside, according to local reports.

The gunman was identified as 32-year-old Jason Nightengale. He was shot down in Evanston, Illinois, and pronounced dead at a hospital later that night. 

The Chicago Police Department has not released information about Nightengale's motive, NBC News reported. 

The rampage started around 1:50 p.m. local time. Nightengale shot and killed a 30-year-old man who was sitting in his car in a parking garage in Chicago and followed with killing a security guard at a nearby apartment complex shortly after. 

He later shot a 77-year-old woman in the head. She survived and is in critical condition, Chicago Police Department Superintendent David O’Neal Brown said at a news conference Saturday. 

Around 3:00 p.m., he stole a car while holding a man at gunpoint. He then drove to a convenience store and shot and killed a 20-year-old while robbing the store. 

Nightengale later shot an 81-year-old woman and struck 15-year-old girl who was riding in a car with her mother -- both the 81-year-old woman and 15-year-old girl are in critical condition. His last target was an Evanston woman whom he took hostage and shot in the head. She’s also recovering from her injuries. 

The gunman ended his spree with a shootout against police. No police officer was killed in the shootout. 

“My brother was not and hadn’t been in his right mind for a long time . . . My condolences to any families affected by his mental break,” the Chicago Sun-Times quoted from a woman who claimed to be Nightengale's sister on Facebook.
