A 92-year-old woman, who was allegedly stomped by her granddaughter Rachel Armstrong in November, died from her injuries on Monday at an area hospital, according to a report from KSDK.
Armstrong, of the 10000 block of Golf Crest in South County's Sappington area, is accused of throwing down her elderly grandmother and stomping on her, breaking both her arms and eight ribs on Nov. 12.
Armstrong confessed to the attack and told police she believed her grandmother was a demon, according to a report from KMOV.
Prosecutors had originally charged her with first-degree elder abuse.
Media Relations Officer Randy Vaughn of the St. Louis County Police told Patch prosecutors are considering changing the charges against Armstrong now that the victim had died.
