Several witnesses said they heard two shots fired in short succession and then saw a masked man, wearing a hooded sweatshirt and dark cargo pants, run west over the Kinzie Street bridge.

“It just seemed like a random shooting,” said Bill Fishback, who was walking towards the building when he witnessed the shooting. “I was coming up the sidewalk when I heard gunshots and saw a guy fall to the ground.”

The shooting occurred as several construction workers were arriving to the building to begin their morning shifts.

“We has just finished smoking a cigarette when we came inside. Then we heard two shots,” said Tim Carmody, who works at a construction site in the building. “The (building) guard turned to us and said, ‘You guys hear fireworks?’”
