ABC7 spoke with Thomas Kendall, the brother of one of the seriously injured victims.

Kendall said his 18-year-old brother was on his way to the Lil Durk concert at the United Center with his friends when a group of people on bikes approached them.

The group then tried to attack the 18-year-old and his friends, Kendall said. A fight broke out and a suspect fired shots.

Kendall's brother, who was shot in the chest, was in critical condition.

Another man, 19, was shot in the rib area and was in critical condition.
