A Gwinnett County woman is in jail after authorities accused her of trying to perform an exorcism on her son. Sandra Alfred, 46, was arrested Friday on charges of false imprisonment and cruelty to children. Police say she used handcuffs to restrain her son and withheld food for three days while attempting the exorcism. The officer who applied for the arrest warrants noted that Alfred may suffer from schizophrenia and delusions. Alfred is being held without bond and is scheduled to return to court June 26. Her attorney, Michael Kay, said he was still investigating and didn't haven't anything to say now.
