Plot summary[]
In 1989, David and Patricia Stallings of Hillsboro, Missouri had their first child, Ryan, whose health took a turn for the worse by the time he was five months old. Ryan had a series of blood tests, which showed unusually high levels of ethylene glycol, which is the main active ingredient in antifreeze.
Patricia Stallings was arrested, and a few days later, Ryan died. While in prison, Patricia gave birth to another son, David, who suffered from the same symptoms as his brother Ryan had; however, he was not in Patricia's care at the time. After re-testing both children’s blood, results showed that there was no evidence of ethylene glycol. It was determined that both children had a rare genetic disorder called methylmalonic acidemia. Patricia Stallings was released on July 30, 1991, as no crime had been committed.
