(Alton, IL)  —  A Missouri woman could spend over two-decades behind bars for killing her two-month-old son while staying in Alton, Illinois.  Wallisha Bland was sentenced Monday to 25-years in prison after pleading guilty last year to murdering Jace Gillespie in 2012.  The baby died of a skull fracture after it was found unresponsive in an Alton apartment.  Investigators determined Bland caused the injury by throwing the child to the floor.
