William Anderson, 65, was last seen leaving Venice Marina in Brooklyn on the morning of December 5, 2000, aboard his 23-foot white and blue Wellcraft named Mary C. He spoke to his fiancée before leaving and said he expected to be back by 3:00 p.m., but never returned. At disappearance he was described as a white male, 6 feet 1 inch, about 190 pounds, brown graying hair, brown eyes, and a mustache; he was wearing a blue jacket, gray hooded sweatshirt, blue jeans, white sneakers and a black plastic wristwatch.

An extensive search turned up no sign of him or the boat. The NYPD Cold Case Squad is handling the investigation.
