A 16-year-old boy was ordered held on $1 million bond today in the fatal shooting of a veteran UPS employee who was gunned down in a robbery as he walked to the "L" on his way to work on the West Side, Cook County prosecutors said.

Rayshon Williams is charged as an adult with the murder of Michael Sullivan, 53.

Williams and another person who has yet to be charged were driving around, looking for someone to rob Tuesday night, prosecutors said in a hearing before Criminal Court Judge Laura Sullivan today. The other person was driving the car with a gun in his lap, and the two saw Sulivan walking to the "L," prosecutors said.

Williams got out of the car, grabbed Sullivan by the arm and demanded money from him, but Sullivan pulled away from him and kept walking, prosecutors said.

Williams got back in the car, and the driver started following Sullivan in the car. Sullivan changed direction to get away from his pursuers, but the driver stopped the car, went over to Sullivan and shot Sullivan in the face, just a few blocks from the Green Line Pulaski stop just after 11 p.m. Tuesday, authorities said.

Officers found Sullivan slumped over on his knees on the sidewalk in the 4200 block of West Lake Street and he died on the scene. The shooting was captured on videotape, according to prosecutors.

"I want justice so I can have peace," said Sullivan's daughter, Lotoya Griffin. "If I don't get justice, I will never have peace. I will never be able to get over this. I cannot put my father in the ground not knowing who his killer is."

Sullivan, a father of two daughters and grandfather of two boys, worked the overnight shift at a UPS facility on the Near West Side, his family said. He was looking forward to retiring.

"I still can't believe it now and it's really hard to sink in," said Sullivan's younger brother, Frederick Sullivan. "But it happened."

Williams was arrested Tuesday when police caught up with him and the driver as they rode in the same car they were in when Sullivan was shot, prosecutors said. Officers tried to stop the car, but it took off at high speed, then stopped when it crashed into a squad car. Williams fled the car, but was arrested. Prosecutors did not say if the driver was apprehended.

Williams admitted to his part in the attack and admitted he knew the driver had a gun before Sullivan was shot, prosecutors said.

Williams was on parole in a juvenile possession of a controlled substance case from 2012 when he was arrested, prosecutors said.
