On April 12, 1982, Leo Kuranuki, 54, a CBS television technician, was shot and killed on the rooftop parking area of Hudson River Pier 92 in Manhattan. Kuranuki and two coworkers confronted a masked figure who was dragging a woman’s limp body toward a waiting van; the gunman responded with close shots to the head, leaving three technicians dead at the scene and one body found farther across the roof. Spent .22-caliber shell casings, discarded shoes and sunglasses, and signs that the abducted woman had been bleeding were recovered at the rooftop.

The woman dragged from the roof was later identified in reports as Margaret Barbera and was found murdered elsewhere in Manhattan the next morning. Investigators linked these killings to an earlier disappearance and presumed murder of Jenny Soo Chin, whose bloodstained car was recovered though she was never found. Authorities treated the incident as a planned, contract-style killing connected to a federal probe into a multimillion-dollar diamond business fraud; Donald Nash (also known as Donald J. Bowers) was arrested within days and later convicted in the murders. Did anyone who worked at Pier 92 or in CBS’s Manhattan facilities in 1982 see anything unusual that night or know the victims’ routines?
