Four people died after an hours-long shooting spree across the Chicago area on Saturday. The suspect was among the people who died in the horrific event.

The shooting spree, which also injured multiple people, occurred at around 1:50 p.m. According to an ABC News report, a man reportedly entered a parking lot on South East End Avenue in Chicago.

The Chicago Police Department (CPD) said the suspect then shot a 30-year-old man who was sitting inside a car. The victim, a college student at the University of Chicago, was pronounced dead at the scene.  

Chicago Police Superintendent David Brown said it seems that what the suspect was doing was random.

Brown said in an ABC 7 Chicago report: "It seems that you have a crystal ball of what he's doing next, and we all know we don't have a crystal ball where he goes next nor do we have this on any of our POD cameras."

He noted that they are responding to the scene as these crimes unfolded and "he's going to the next" while police are trying to keep up with what's happened previously.

Chicago police named the suspect as 32-year-old Jason Nightengale, who was killed by Evanston police to end an hours-long shooting spree. Law enforcement said that Nightengale posted a slurred and rambling social media video before the shooting spree.

The Shooting Spree Victims

Besides the 30-year-old student, other victims include a woman who was shot after being taken hostage at an IHOP restaurant in Evanston, according to police.

Law enforcement initially said that seven people had been shot and five were killed. But on Sunday, they amended the count to three people who died in the shooting spree.

Police and school officials confirmed that the University of Chicago student was killed in the parking garage of the Regent Park apartment complex in South East End Avenue. According to officials, the university was informed that one of their students was shot in a car.

In a statement, the university said it is harrowing news to the community and the South Side neighborhood. The university added that it would provide support for members of their community affected by the shooting.

The university also identified the student as Yiran Fan, a PhD student in a joint program of the Booth School of Business and the Kenneth C. Griffin Department of Economics.

After the suspect shot the student, police said he then entered an apartment building on the same street around 2 p.m. and shot at a female security guard in the chest and a 77-year-old woman retrieving her mail.

Police said the victims were rushed to the University of Chicago Medical Center, where the security guard pronounced dead, while the older woman remains in critical condition, Buzzfeed reported.

According to the police, the suspect also entered a South Halsted Street store around 3:45 p.m. and announced a robbery. The suspect then fired multiple shots at people inside the store. 

He struck a man, 20, in the head and a woman, 81, also in the head and back. Police said the two victims were taken to Advocate Christ Medical Center, where the man died, while the woman remains in critical condition.

The suspect then fled the scene in a vehicle, and around 5 p.m., he shot a 15-year-old girl in the head. Reports said the teenager was riding in the back of a car driven by a relative along South Halsted Street. Police said she was in critical condition at the Comer Children's Hospital. 

The suspect then went into a CVS store in Evanston and announced a robbery, and fled to the IHOP, where he shot a woman he had taken hostage in the head. Police said the woman was taken to a hospital and in critical condition. 

According to a New York Times report, the shooting rampage came to an end when responding cops shot the suspect as he attempted to flee but failed as he collapsed.
