Real Name: Patricia Stallings
Location: Jefferson County, Missouri
Date: July 8, 1989
CaseEditDetails: When five-month-old Ryan Stallings became violently ill, his mother, Patricia, rushed him to to the hospital, but she became misdirected, and eventually took him to another one. Doctors were able to stabilize his conditions, but their conclusions from his symptoms made them think that he might have been poisoned. Several weeks later, he passed away, and again poisoning was suspected. Patricia was convicted of poisoning him and was sent to prison swearing of her innocence. She had another son, David Jr., while there, and doctors found that he was ill with MMA, and that is what many believe that Ryan died from, but prosecutors still believe that Patricia was guilty.
Suspects: None known
Results: Solved. This case dragged out much longer as doctors interested in it suspected Ryan actually suffered from MMA, a rare genetic disorder similar but not identical to antifreeze poisoning. After two more trials, Patricia was finally exonerated of the abuse charges.
