“(Guys) jumped out shooting at him. He shot back,” James said.

Williams would stop in about twice a week to grab popcorn, leaving smiles and friendly conversation. A customer for more than 25 years, on Thursday he exited for a final time. His maroon Jeep Cherokee left at the crime scene. James is now left wondering what it’s going to be like to never see his friend walk though the door again.

“Your heart drops,” James said. “It’s painful.”

Prayers and about a hundred roses are left in the spot where Williams’ body was found. The father of four remembered by strangers, friends and family.

“This is a really great loss,” Armstrong-Williams said. “Not only to my family, but to all the citizens in Chicago. I want justice to be served.”
