Authorities said Dericka’s parents, Grace Joan Smith and James Edmund Smith, had sought Posey’s help to punish the child on Oct. 14, 2017. Posey reportedly struck the girl with a ruler and a metal pipe before Dericka ran to an armchair. The 320-pound woman then sat on top of Dericka for at least five minutes before the girl complained that she could not breathe, prosecutors said.
