In April 1989, three young children perished in a Los Angeles house fire. Their mother, Jo Ann Parks, managed to escape with her own life, but was bereft. When he arrived at the scene of the fire, her husband accused her of abandoning the children. It was soon determined that a worn extension cord was the cause of the tragedy. But as firefighters investigated, they came to believe they were dealing with an arson; Jo Ann Parks was convicted, and has languished in prison for twenty-five years. But now, as investigative methods from that era are debunked, lawyers from the Innocence Project believe that Jo Ann was wrongfully convicted.
