"He would do anything for you, and we had plans on going out tonight to celebrate his girlfriend's birthday," said a tearful Arnetta Ambrose, the man's sister.
The shooting took place in the 1600 hundred block of East 67th Street near Cornell. The Independent Police Review Authority confirms that an officer shot one man, who was taken to Northwestern hospital.
Witnesses at the scene tell ABC7 Chicago the man was shot several times, and they say they watched the chaos unfold. They say a man driving a van went the wrong way on a one-way street.
"He was going the wrong way on the one-way, but when he backed up, I don't know if he was trying to get out of the way or run, I don't know what his intentions were, but he backed up, and the police car hit the back end of his van," witness Malissa Keith said.
According to witnesses, the driver went down an alley with an unmarked police car right behind them.
"When they got to the end on Cornell, I'm running in the alley, you could see the van door open, and all you heard was gun shots. It had to be at least 15 or 20 [shots]," said Keith.
Once the driver jumped out of the van, witnesses say he had a gun.
"As soon as he put his gun down, they started shooting," said another witness who identified himself as Jay W. "He did [have a gun], but he put it down. He did everything the right way."
Authorities say a gun has been recovered at the scene.
Witnesses also tell ABC7 Chicago that the man who was shot was 26 years old, and that he had relatives in the community.
There are also reports that there was another passenger inside the van at the time of the shooting. It was not known Friday evening what happened to that passenger.
