Anna Marie Steffen, 28, vanished from Rochester, New York, with her last known whereabouts traced to July 9, 1988. Weeks later human remains were recovered along the Genesee River corridor; the condition of the remains and exposure made identification difficult and the cause of death hard to determine from the remains alone.

A forensic reconstruction from the skull was circulated publicly and recognized by her father; dental records confirmed the identification. Her family reportedly suspected someone from the dangerous circles she frequented, such as a drug dealer or pimp, though no clear suspect had emerged at the time.

Investigators later linked Steffen’s death to a broader series of Rochester-area killings. In early January 1990 Arthur John Shawcross was arrested; prosecutors connected him to multiple murders and a jury convicted him in December 1990 on ten counts of second-degree murder. Would anyone who knew Anna or her circle in 1988 come forward with details that might clarify what happened that summer?
