Robin Lee Row needed money to pay off her excessive spending. Her solution was to set her Pocatello, Idaho house on fire with her husband and two kids inside. But her watertight alibi led police on a wild goose chase for clues and a conviction - leading to dark secrets from her past and only one way to expose her. Robin was sentenced to death. Marybeth Tinning of Duanesburg, New York loved the attention that she received after her third child died of meningitis as a baby. To keep receiving that attention, she quietly killed her other eight children over a span of years. She was seen as a woman with a series of unfortunate events, until she went one step too far by smothering her adopted son. Marybeth was sentenced to 20 years to life and was released in 2018. To make sure she did not lose her kids to her husband in a custody battle in Northridge, California, alcoholic con-artist Cora Caro got revenge on her unfaithful husband (both were seen as caring Christians) by shooting their three eldest sons and attempted suicide by shooting herself in the mouth, barely surviving. Caro was sentenced to death.
