The victim of Munchausen by Proxy, who went to prison for her participation in the murder of her abuser, her mother, Dee Dee Blanchard, speaks with us about her new freedom.

Men commit murder 10 times more often than women. But just because a woman's fingerprints aren't at the crime scene doesn't mean her fingerprints weren't on the plan. We look at some memorable cases of men killing for their sweethearts.

Gypsy Rose Blanchard and a former boyfriend are in prison for the murder of Gypsy's mom, Dee Dee Blanchard, who was believed to have an attention-seeking psychological condition, Munchausen syndrome by proxy. We speak with Gypsy Rose's father, Rod Blanchard.

Gayani DeSilva, M.D., a child and adolescent psychiatrist and author, tells us about the warning signs of Munchausen syndrome and why cases involving the disorder—like that of Gypsy Rose and Dee Dee Blanchard-—are so horrifyingly fascinating.
