Readers in search of truly strange true crime story should definitely check out the documentary Mommy Dead and Dearest , which premieres on HBO on May 15 at 10 p.m. ET.

Directed by Erin Lee Carr (Thought Crimes: The Case of the Cannibal Cop), the film details the story of Dee Dee Blanchard and her wheelchair-bound daughter, Gypsy Rose, who were once beloved residents of Springfield, Mo. That tight-knit community was rocked when Dee Dee was found murdered in her home, with Gypsy reported missing. After investigators tracked a graphic Facebook status post stating “that Bitch is Dead” to Wisconsin, a disturbing sequence of events ensued in which Gypsy Rose was implicated in her mother’s murder – and it was discovered that Gypsy Rose had been the victim of her mother’s abuse via Munchausen by proxy syndrome since early childhood.
