Join Katie and Liz on a very intense mini-episode in their case profile series. First, Katie starts off by telling the story of the disappearance of 5-month-old Marlon Devine Santos, who was living in a neglectful and atrocious foster home in Massachusetts when he went missing in 1998. Then, Liz tells the details of the discovery of two black teenagers decomposing bodies in Dorchester, Massachusetts in 1988, whose identities remain unknown to this day. If you or anyone you know has information regarding Marlon Devine Santos, please call the Worcester Police Department at (508) 799-8651. If you or anyone you know has information regarding the Eldon St. John Does, aka "Clayton" and "Hooker," please call Detective Cronin at (617) 343-5837.
