Margaret J. Miller was 17 when her body was found in a vacant lot near 37th Street and Garfield Avenue in Kansas City, Missouri, on Sunday, May 9, 1982. An autopsy determined she died by strangulation. At the time she worked as a prostitute on Troost Avenue; some personal items, including her underwear and a bra with a key attached, were missing from the scene.

The case went cold for decades but was later tied to a string of similar killings through DNA evidence. Authorities identified Lorenzo Gilyard as a suspect after a 1987 blood sample was matched to multiple crime scenes. Gilyard was arrested in April 2004; he was publicly linked to at least 13 women killed between 1977 and 1993, many of whom were sex workers and found strangled and left in secluded locations. Gilyard was tried in March 2007 on seven murders and convicted of six counts of first-degree murder; the charges in that trial did not include Miller’s death, though law enforcement says he was responsible for her killing.

Did anyone who knew Margaret or who was in that part of Kansas City in 1982 see anything that might still be useful to investigators?
