30-year-old Sacha Brown of Jonesboro will be back in an Illinois courtroom in March for her role in the death of a 4-year-old boy.  Brown was arrested December 12^th, 2011, and is charged with 1^st-degree murder, aggravated battery, and concealment of a homicide.  She is not the child’s mother.  According to deputies, she allegedly killed the boy to cover up a skull fracture he suffered while in her care.  An autopsy on 4-year-old Justin Hepburn revealed the injuries.  Judge William Thurston Wednesday set her jury trial for March 11^th, 2013, in Jonesboro.  A pre-trial conference is slated for October 17^th.  She faces life in prison if convicted.
