Sean Hawley, 25, was last seen on May 9, 2015, paddling a black inflatable kayak on Lake Champlain near Burlington, Vermont. Witnesses placed him around 11:00 p.m. in the Oak Ledge Park area heading toward Plattsburgh, New York. He did not tell anyone of his plans, and family reported him missing when he couldn’t be reached.

In the days after his disappearance, authorities recovered Hawley’s kayak and camping gear on Stave Island, about two miles from where he was last seen. He was believed to have spent time on the island, but he has not been seen or heard from since. A Coast Guard operation and other search efforts were conducted before the search was eventually called off. Investigators do not suspect foul play, though there are serious concerns about his well-being.

The case remains unsolved and his whereabouts are unknown. Does anyone who was on or near Lake Champlain that night have information that could help locate Sean?
