On the Trail of an Intercontinental Killer

A little after 9 a.m. on Sept. 15, 1990, the owner of a steel-products company pulled up to her office in Vinegar Hill, near the Brooklyn Navy Yard, and spotted a black garbage bag sitting on the sidewalk out front. She parked her car and went to move the bag when she noticed it leaking blood. The woman called 911. Within the hour, Ken Whelan, a homicide detective from the 84th Precinct, peered into the bag. It was full of human body parts.
