Joan Richburg, 24, vanished from Colonie Center on December 23, 1976, during last-minute holiday shopping. Investigators concluded she was followed from the mall into a more secluded part of the parking lot, where she was sexually assaulted, brutally mutilated, and left in her vehicle. Police found her body the next day.

Her killing drew attention amid other violent crimes in the Capital District. Investigators focused on Lemuel Warren Smith, a recently paroled man whose movements and forensic connections—including hair evidence—linked him to a string of attacks in the region. Smith was arrested on August 19, 1977, after further assaults led to a traffic-stop arrest; he later confessed to multiple killings while mounting an insanity defense and was indicted in Richburg’s murder.

Prosecutors ultimately dismissed the indictment against Smith because he was already subject to sentences that would keep him confined for life, so Richburg’s death was never prosecuted at trial. Anyone who knew Joan, saw her that day at Colonie Center, or has information about her case is asked to come forward.
