Summary based on the NamUs case record (MP9562) and 5 other sources
In the early morning hours of December 5, 2000, 65-year-old William Anderson embarked on what was planned to be a day of fishing. He was last seen at approximately 7:00 a.m. in Brooklyn, New York, as he departed from the Venice Marina. Anderson, a resident of Brooklyn, set out on his 23-foot white and blue Wellcraft boat, which was named the 'Mary C'. Before his departure, he spoke with his fiancée, informing her that he intended to return to shore by 3:00 p.m. that afternoon. However, William Anderson did not return as planned, and has not been seen or heard from since that day.

At the time he went missing, William Anderson was described as a white male, standing at 6'1' and weighing around 190 pounds. He had brown hair that was graying and brown eyes. A notable feature was a mustache he had at the time of his disappearance. When he was last seen, he was wearing a blue jacket, a gray hooded sweatshirt, blue jeans, and white sneakers. He was also wearing a black plastic wristwatch. These personal details, along with the specifics of his boat, were provided to law enforcement to aid in the search efforts.

Following his failure to return to the marina, an extensive search was launched in the waters surrounding the area where he was last seen. Despite these thorough efforts, no trace of William Anderson or his boat, the 'Mary C,' was ever discovered. The complete absence of any evidence has left his family, friends, and investigators without answers. The New York City Police Department's Cold Case Squad is handling the investigation into his disappearance. The case remains an unsolved missing person case, a heart-wrenching mystery for those who knew him, as a day that began with the simple pleasure of fishing ended in an enduring and unresolved absence.
