CHICAGO (CBS) — Chicago saw more than 50 shootings this weekend, eight of them fatal – including one incident overnight Saturday into Sunday right downtown.

As CBS 2’s Marissa Parra reported Sunday night, the south bank of the Chicago River at Wabash Avenue is bustling by day. But this weekend in the wee hours, it turned into a crime scene.

“I was probably 20 feet away and I heard the gunshots and I just ducked,” said witness Solomon Williams.

The victims were in a car in the 0-99 block of East Wacker Drive near Wabash Avenue around 2:30 a.m. when they waved down officers for help, according to Chicago Police.

Police said a quarrel between an unidentified man and a group of people led to that same man taking out his gun.

“‘Boom! Boom! Boom!’” said witness Travis Whitaker. “Next thing you know, shorty’s laying there.”

A 35-year-old man was shot once in the neck, and 25-year-old woman was shot once in each arm. Both were taken to Northwestern Memorial Hospital, and the man died a short time later. The woman was reported in good condition.

“Just another story in the Black community,” Whitaker said. “It’s sad.”

As police responded to the crime scene, the Department of Streets and Sanitation responded by cleaning up a mess of empty bottles and trash.

People who work in the Loop along Wacker Drive said street parties have ramped up over the last few weeks.

Videos taken from Snapchat maps showed large groups of people dancing and drinking along the Riverwalk below in the middle of the night.

“Last night was probably the most packed we’ve seen it in the past three days,” Williams said.

He said he came out to have fun, but then the mood quickly shifted.

“When everyone got together, you could kind of tell the hostility, you know, when it’s a large group of people,” Williams said. “Me personally, I’m all right. People still just got to be aware and be careful.”

It is not clear where exactly the actual shooting happened. But when police found the car with the two victims, it was in front of the entrance to the Club Quarters Hotel at the Mather Tower, 75 E. Wacker Dr.
