An anthology of True Crime focused on women who killed children, even their own. ALEXANDRA TOBIAS - On January 19th, 2010, 22 year old Alexandra Tobias was playing Farmville on Facebook at home in Jacksonville, Florida when she was interrupted by the cries of her three month old baby, Dylan. She tried to silence him by shaking him roughly - hitting his head in the process. The child fell unconscious and she placed a frantic call to 911. The child would be taken to the hospital where he would die the next day. Alexandra would be arrested for second degree murder. Just over a year later, on February 1st 2011, Tobias was sentenced to 50 years in prison. "He who is the most defenceless among us was murdered by his own mommy. And why? Because he was crying during a game of Fishville or Farmville or whatever was going on during Facebooking time that day," the presiding Judge Adrian G Soud said. In the time between the crime and the sentencing, news organizations across America picked up the story.Why would Alexandra kill her baby?KATHLEEN FOLBIGG - Kathleen Folbigg was a serial child killer who murdered her three infant children and was convicted for the manslaughter of a fourth. Her killings would take place over the course of an eight-year period during in which she was never suspected. She would only be discovered after her husband discovered her personal diary in which she detailed the motivations behind her killing spree. This is her story.SUSAN SMITH - The idea of a mother who kills her children will always capture the attention of the nation, and in some cases the entire world will tune in as they did in Smith's situation, at first with sympathy and then with outrage. Why would someone commit the most unspeakable of acts? How could a mother kill her child? In 1994, these questions were asked of Susan Smith, a young woman living in Union of South Carolina during an unusual case.CHRISTINE RIGGS - Christina Marie Riggs was convicted of murdering her two young children in Arkansas in 1997. Three years later, she would become the first woman executed in that state since 1845.
