A judge denied bond for Mitchell, 23, on Tuesday. He is also charged with one count of first-degree murder and three counts of attempted first degree murder.
"He thought the people in the car that he was shooting at were opps. He said that 'this wasn't for the lady' and that 'she was in the wrong place at the wrong time,'" said Assistant Cook County State's Attorney Jim Murphy.

Dickerson worked as a pharmacy technician at Norwegian American Hospital for 14 years. A ceremony was held in her honor Tuesday, where her family and friends shared stories of her infectious spirit and kindness.
To help support Dickerson's family, the hospital has also established a benevolence fund for her three sons. So far, they've been able to raise more than $15,000.
Hospital officials said they also plan to give her oldest son a summer job so he can follow in his mother's footsteps, if he decides to do so.
