A southwestern Illinois woman is jailed on $500,000 bond after being accused of abusing her 7-week old baby boy, causing him to sustain broken ribs and a fractured leg.  Prosecutors in Saint Clair County charged 22-year old Che Watson of Fairview Heights with two counts of aggravated battery of a child.  Authorities say that on November 24th, police were called by state child-welfare officials to investigate injuries sustained by a baby boy being treated at a Saint Louis hospital.  Investigators say the boy was later released to the custody of unspecified relatives.
