In the winter of 1999 in Detroit, Michigan, sex worker Monica Johnson entered a Jeep Wrangler with the licence plate 'Baby Doll' with a client. That client, John Eric Armstrong, brutally murdered her and placed her body face down on the sidewalk, before returning home to his wife and young son. Monica was one of several women he killed between 1992 to 1999 before the police finally closed in. Journalist and author B.R. Bates, co-author of The ‘Baby Doll’ Serial Killer: The John Eric Armstrong Homicides, is one of the few individuals who has interviewed Armstrong himself.
