A Gwinnett superior court grand jury indicted the mother-in-law of a Conyers woman who was shot to death in a Target parking lot in April. Police arrested Joanna Hayes, who had been staying in Merriweather County, on Wednesday, after the grand jury pronounced the indictment and an arrest warrant was issued, and taken to the Gwinnett County jail. Hayes was charged with malice murder, felony murder, aggravated assault and possession of a firearm during the commission of a felony for allegedly shooting and killing her daughter-in-law, according Snellville Police Chief Roy Whitehead.
