How Lois Riess Became the "Killer Grandma"

The HBO documentary I'm Not a Monster: The Lois Riess Murders details the life and crimes of Lois Riess, a seemingly ordinary grandmother who murdered her husband and another woman who resembled her. The documentary features interviews with Riess herself, as well as her family, friends, and law enforcement officials. Riess claims she was a victim of domestic abuse and that her husband's murder was a result of her snapping, while the documentary explores the evidence that suggests she committed both murders to escape her financial troubles and a potential investigation into her theft of money from her disabled sister. The film chronicles Riess' cross-country escape and eventual arrest, culminating in her current imprisonment for two life sentences.
