Violet O’Neill, 21, was last seen in New York City on July 16, 1992, while staying with her grandmother. In the days after her disappearance, severed human remains were recovered from multiple spots around Manhattan’s waterways—some wrapped in plastic, some contained as if discarded like luggage. Investigators pieced together parts recovered over several days to establish an identity; the way the remains were packaged and scattered suggested planning and intention.

Nearly a year later, the arrest of Joel David Rifkin followed a June 28, 1993 traffic stop and chase on Long Island in which an inventory search turned up a body in the vehicle. Rifkin was identified as the only publicly named suspect in O’Neill’s killing, and authorities ultimately listed her among the victims attributed to him based on recoveries fitting the same pattern of dismemberment and disposal.

Does anyone have information about Violet’s last known movements or who she was close to in July 1992?
