In 2009, after her release from the LA County Sheriff’s Department on a minor arrest, Mitrice Richardson walked into the night and vanished. Her naked, mummified body was discovered months later in a remote Malibu Canyon creek bed. Authorities said the cause and manner of her death were undetermined. Mitrice’s family accused the department of botching the investigation, mishandling her remains, and ignoring signs of foul play. They also failed to get answers from the last person who saw her alive: a man with a violent past living in a wilderness fort near the creek.

“Lost Hills: Dark Canyon” is the fourth season of the true crime podcast from Pushkin Industries and Western Sound. Host Dana Goodyear traces Mitrice’s last steps in an effort to learn how she died. She also identifies a new person of interest and tries to do what detectives couldn’t: get evidence against this prime suspect.
