Cecilia Marie Knott was 23 when her body was found in northwest Detroit on November 7, 1980. She was discovered nude with a sweater wrapped around her neck and had been stabbed to death. Reports say her body was discarded in the Littlefield area.

The investigation into a string of similar killings eventually produced a confession from Donald Murphy. Murphy told investigators he had solicited Knott the day before, stabbed her in the chest and neck while they were together, and later discarded her body. Another man, David Payton, had been wrongfully arrested earlier in the inquiry before Murphy identified himself as the attacker. Murphy also confessed to the murder of Cynthia Angela Warren and to at least four other killings, but prosecutors charged him only in the Knott and Warren deaths.

On January 7, 1982, Murphy entered a court confession as part of a plea bargain and was convicted for the murders of Cecilia Knott and Cynthia Warren, receiving concurrent terms of 15 to 30 years for each slaying. Does anyone have memories of Knott or details about the northwest Detroit or Littlefield area from 1980 that could add context to this case?
