ITASCA, Ill. – Chicago police received a break in the Fulton River District shooter case from a suburban police department.

After CPD showed high definition photographs of the alleged shooter, 45-year-old Michael Blackman, talking in a bike shop prior to the shooting of a woman, Itasca police recognized Blackman from thefts in their community.

Itasca police believe Blackman burglarized three closed businesses in June and July. Detectives said they recognized him from surveillance video they had near the area of those burglaries.

Detective Anders Langlo contacted Chicago police after he said he recognized Blackman on the news Thursday.

“We’ve been looking with some other jurisdictions in this area and yeah, it just clicked,” Detective Langlo said. “I think this is the same person of interest.”

That tip not only helped Chicago police identify him as the alleged Fulton River District shooter, it helped detectives spot him allegedly hiding out Saturday in West Englewood.

CPD’s technology team then used more cameras to track Blackman there, where he allegedly shot a CPD officer as they tried to arrest him.

Hours later, the same technology team located Blackman hiding out in an empty home blocks away. Blackman reportedly ran out of the home and later fired at officers.

Police returned fire and he was shot multiple times.

The CPD officer who was shot is in stable condition and expected to undergo more surgeries. Blackman remains in critical condition.

He was officially charged with the shooting of the officer and the woman in Fulton River District on Monday.
