At least three search-and-rescue dog teams were involved in efforts to find LeMaitre, which completed a preliminary search of the entire east face of Mount Marathon Thursday. Teams had planned to begin searching the more treacherous west and south sides of the mountain Thursday evening, before the search was suspended overnight.
AMRG spokesperson Dean Knapp says there is snow on the top of the mountain but no snow tracks, which makes searchers confident that LeMaitre isn't near the top. The southeast side of the mountain and the vicinity of the race trail have also been cleared.
LeMaitre's family reported him missing at about 7 p.m. Wednesday. Race officials say LeMaitre, a lottery participant in Mount Marathon's 3 p.m. men's race who was wearing bib 548, was last seen headed uphill about 200 feet from the top of the mountain at about 6 p.m.
Troopers say LeMaitre suffers from poor eyesight, while race officials said he was wearing black running shorts and a black T-shirt-- but not his glasses.
According to Knapp, searchers are considering the theory that LeMaitre made it to the top of the mountain Wednesday, but took a wrong turn at the turnaround point for runners to descend. A glove and water bottle were found along the trail Thursday, which will be brought to LeMaitre's family to see if they're his.
Seward Police and Fire led an initial search for LeMaitre, and a trooper familiar with the course walked it in an effort to locate him. AST spokesperson Megan Peters said Thursday that searchers expected to find LeMaitre.
"We have every reason to believe he's on the mountain," Peters said.
Michelle Lynn, LeMaitre's daughter, said he is in fairly good health, and was in a good mood before starting Wednesday's race. His family expected him off the mountain by 9 p.m. Wednesday night.
"He was excited to do it," Lynn said. "One of the racers who saw him near the top said that he was adamant on getting to the top and that he was still walking on up."
Lynn says that was the last anybody saw of him.
Lynn says LeMaitre isn't the kind of person who would walk away from plans without telling anyone.
"He's very devoted to his family, so he would never cause unnecessary stress to us like this," Lynn said.
