THR Erin Lee Carr - H 2015

'Mommie Dead and Dearest' focuses on a 2015 murder case in which a wheelchair-bound girl was charged with murdering her mother.

HBO Documentary Films will present director Erin Lee Carr’s new true-crime documentary Mommy Dead and Dearest in March, it was announced Thursday.

In her last film, Thought Crimes: The Case of the Cannibal Cop, Carr explored the case of Gilberto Valle, who was dubbed the "Cannibal Cop" by the New York tabloids. In her new film, she takes on another case that triggered lurid headlines, the case of Dee Dee and Gypsy Rose Blanchard.

Blanchard, who lived with her ailing, wheelchair-bound daughter, Gypsy Rose, was found stabbed to death in her home in Springfield, Mo., in June 2015, and her daughter was charged with the crime, which led investigators to discover a pattern of deception that involved child abuse and mental illness. The film, which includes exclusive prison access to Gypsy Rose, also examines the psychological condition known as Munchausen syndrome by proxy.

“I am thrilled to be back at home with the team at HBO to bring this incredibly complex case and tragic story to audiences,” said Carr.

In addition to directing Mommy Dead and Dearest, Carr produced the film along with Andrew Rossi. For HBO, Sara Bernstein served as senior producer, and Sheila Nevins was executive producer.
