The bodies of a father, son and family friend have been found in Lake Superior after disappearing more than two weeks ago while on a fishing trip.

Search teams found the bodies of 43-year-old Steven Chartre, his 9-year old son Ethan Chartre, and the boat’s owner, 61-year-old Keith Karvonen, just before 1:00 p.m. Saturday, 9&10 News reported.

Their disappearance spawned a massive search, including the U.S. Coast Guard, local authorities and volunteer organizations.

Two volunteer groups in particular, Bruce’s Legacy from Black River Falls, Wisconsin, and Crossman Consulting of Duluth, Minnesota, utilized sonar which ultimately led to the discovery of the missing boat, WLUC reported.

The three left for a routine fishing trip on Sept. 17th from Chassel, Michigan, and were reported missing that night when they failed to arrive at a scheduled event.

The Coast Guard searched more than 14,000 square miles spanning 151 hours before calling off its search on Sept. 21, mlive reported.

It’s not clear what may have caused the boat to sink.
