EVANSTON, Ill. – Evanston police have released body cam footage that shows the death of the gunman responsible for a deadly shooting spree that killed four people earlier this month.

The video shows the death of 32-year-old Jason Nightengale, who police said fired shots at them after killing a total of four people.

It all started on the night of Jan. 9 at 53rd and East End where he killed a doctoral student at the University of Chicago. He then shot and killed two more people and wounded three others before heading north to Evanston.

Police said he shot and killed a woman in an IHOP before police zeroed in on him. The video shows a barrage of bullets fired by officers at Nightengale.

He was pronounced dead at a nearby hospital.

Nightengale had an extensive criminal record and police said his motive remains unclear at this time.
