Six teenage boys, including 16-year-old Robert Lloyd Rumbolt, left a Pickering party in the early hours of March 17, 1995, and were last seen walking toward the East Shore Marina at Frenchman’s Bay. Surveillance placed three of the group at the marina at 1:48 a.m.; witnesses later reported hearing a motorboat between about 2:30 and 3 a.m. The boys told a friend they were going to goof around on a boat.

A 14-foot Boston Whaler–type boat and a three-wheeled paddle boat were reported stolen from different marinas that morning. Water temperature on Lake Ontario that night was estimated at about 2 degrees Celsius, and hypothermia would have set in within minutes if a vessel capsized. Search and rescue began the afternoon of March 18—about 36 hours after they were last seen—and involved local police, marine units, the Coast Guard and military aircraft, yet no bodies, wreckage, clothing or personal effects were ever recovered; a gas can later washed up on the U.S. side of the lake.

The prevailing theory is a boating accident leading to drowning, but the total absence of physical evidence means the case remains unresolved. Did anyone in the area that night notice a small boat or remember unusual activity around the marinas?
