The U.S. Department of Justice is investigating whether the St. Louis County family court is treating all of the children who appear in front of its judges equally.
The department's Civil Rights Division is specifically looking at whether the court is providing due process to children involved in delinquency proceedings, and if all children are treated equally regardless of race.
Illinois lawmakers are considering a change that would keep more teenagers out of adult court. The measure, which so far has had bipartisan support, would send 17-year-olds charged with non-violent felonies into the juvenile court system.
Since 2010, 17-year-olds charged with misdemeanors have been sent to juvenile court, while those charged with felonies are sent to adult court.
