Michael LeMaitre, 65 and an Anchorage resident, vanished while running the Mount Marathon Race in Seward on July 4, 2012. It was his first time on the course, a steep 3.1 to 3.5-mile route that climbs more than 3,000 feet and features shale, snowfields and waterfalls. He was last seen by a race official at about 6:00 p.m., roughly 200 feet from the summit, as fog and cold were setting in. He wore a black shirt, black shorts, running shoes and bib number 548.

Hazardous conditions that year included recent rain that left the trail slick and muddy and produced multiple serious injuries among participants. When LeMaitre did not return, a search involving up to 70 people — Alaska State Troopers, Seward Volunteer Fire Department, Alaska Air National Guard and mountain rescue teams with helicopters and dogs — used infrared scans but found no trace. The official search was scaled back after four days; volunteers and family continued searching for weeks. LeMaitre was later declared dead in August 2012, but no physical evidence from him has ever been recovered, and the investigation remains active.

The lack of any clothing, gear or even the race bib leaves major gaps in the timeline and location of his disappearance. If anyone was on Mount Marathon that day or has information about unusual findings near the summit or along the descent, please share what is known.
