Prosecutors said the victim's mother dropped him off at a McDonald's in Streamwood on Dec. 31 to meet a friend. He later asked to stay at the friend's place both that night and the next. But by Monday, the family was no longer hearing from the teen. Later that same day, however, the victim's brother found out on Facebook that his brother was with Hill. The mother reached out to Hill on Facebook to say she wanted her son to return home, prosecutors said.
