A Decatur woman is in jail after she allegedly slammed her 5-month old son's head against a hard floor and fractured his skull, because he would not stop crying.

18-year-old Heather R. McKinney also allegedly broke the baby's ribs, collarbone and bones in both legs.

The paper says McKinney was arrested this week on preliminary charges of aggravated battery to a child and child endangerment. According to the paper, the woman told police she slammed the baby a number of times into his swing set and then when he continued to cry slammed his head against the floor.

The boy was taken to Decatur Memorial Hospital Friday and transported to St. John's Hospital in Springfield.
