Lead #3Why did a fully-fueled boat with significant cargo sink—was there a structural failure, collision, or other mechanical issue?
Sean Cone, a 24-year-old male, went missing on January 30, 2007, while operating his fishing boat, Lady Luck, approximately 30 miles off the coast of Portland, Maine, with fellow crew member Daniel Miller. The vessel was discovered at a depth of 500 feet, and the U.S. Coast Guard suspected the boat became flooded and sank, though the exact circumstances and fates of both men remain unclear. Despite the boat's recovery, questions persist about what caused the sinking and whether either man survived the incident.
