The cops were not injured, and the suspect was pronounced dead at the hospital.
Officials believe the gunman killed three people earlier that day in the central Illinois town of Mahomet, about 140 miles south of Berwyn.
The victims were identified as three family members: Sara Mason, 26, Janis Mason, 61, and Caleb Mason, 23.
It's unclear why they were targeted and what connection, if any, they had to the suspect or Fuentes.
Cops declined to comment on the video but confirmed a triple murder suspect was shot and killed in the area.
The Berwyn Police Department responded to calls about a man with a gun in Berwyn, a suburb of
Chicago, just before midnight on Wednesday night.
When cops confronted the suspect, he ran off and broke into a neighboring home, where he fatally shot two dogs, according to Berwyn PD.
Police confronted the man again in the street, where he shot at officers, who returned fire and fatally wounded him.
This story makes absolutely no sense. First he kills a family for what apparently is no reason, then he tries to carry out the worst assassination attempt I've seen in my life. Oh wow walking up to the dudes door and knocking and calling his name didn't make him open the door?! Shocker. And then he runs into another house shoots two dogs and then gets into a shootout with the Police for... What? Did the government try to MKUltra Nick lmfao These actions sound like someone who isnt in control of their mind at all. Wild story. They've buried this dudes name as far as I can tell to 3 articles I've read so far not one mention ot the dudes name why is that?
