A Chicago judge has issued an arrest warrant for rapper Chief Keef for failure to appear in court. Keef was to appear in court July 14th in a child support case. The rapper reportedly owes $10,000 in back child support for his 17 month old daughter. According to the child mother Erica Early, Keef had made a few payments earlier in the year but never caught up on his obligations. This is the second pending child support case against Keef in Cook County.
