At least 20 people were shot during weekend violence in Chicago — including one gunned down just blocks from the site of the upcoming Democratic National Convention.

Just after 1 a.m. Sunday, a 21-year-old got into a car wreck with a black truck on the 500-block of Damen Avenue, less than a mile north of the United Center where the DNC will kick off Monday to presumably nominate Kamala Harris for the Democratic presidential ticket.

The driver of the truck reportedly unloaded a weapon at the 21-year-old, striking him in the head, cheek, and shoulder before fleeing.

He was left in critical condition, according to ABC 7 Chicago, and no suspects have been identified.

Around the same time across town on the Lower West Side, a man and a woman were found shot to death in a car.

Officers responding to the sound of shots encountered a group of armed suspects near the car and opened fire at them, striking one who later died at a hospital.

On Saturday, a man and a woman were standing outside just before 5 a.m. when shots rang out and they were struck.

The man, 53, was hit in the abdomen and later died, while the woman, 41, was hit in the ankle. A third victim, 33, was struck in the foot.

Another shooting Saturday on the Southwest Side left a 30-year-old dead after a man approached him, shot him in the neck and back, and then fled.

At least four people were killed during the weekend violence, but it was a relatively tame weekend for Chicago.

Last weekend, 33 people were shot and one was killed, while the weekend before 48 were shot and five were killed.

Over the Fourth of July holiday weekend, at least 109 people were shot, 19 of them fatally.
