Military joins search for Marty Leger, missing cyclist

About 250 members of the military have joined the search in Waverley, N.S., Monday morning for a mountain biker missing since Thursday.

Marty Leger was expected home Thursday afternoon. He told family he was going for a ride on his mountain bike near Spider Lake.

One of the search members is Larry Labadie, a civilian RCMP member flying a search helicopter.

"The area is fairly large here and with the helicopter, it gives you a good tool to cover that area pretty quick," said Labadie.

He said the helicopter has two trained spotters, one on board each side.

"It's a good tool, but you still need that search from the ground. You don’t know what could be hiding underneath the trees," he said.

Labadie has been with the RCMP for ten years. It's the first time he's seen the military join such a search.

The current search zone is 80-square kilometres, most of it dense woods and rough terrain.

“We realize that after the weekend, searchers — some have to go home back to regular duties — and we did not believe we could sustain the number [of search crews] so we put the ask out to Canadian Forces and they have obliged,” said RCMP Cpl. Scott MacRae.

Police also say they're looking for a man they believe was in the area at the same time as Leger on Thursday.  

“This male was believed to go into the woods shortly after Mr. Leger. We would like to speak to him, just hoping he might have some information,” said MacRae.

They believe he was driving a silver vehicle, possible a Subaru, with a bike rack on the roof.

“We’re actually looking for anybody who may have been in and around the Spider Lake area, the trail, Thursday afternoon when Marty Leger went biking,” said MacRae.

Search and rescue crews from all over the Maritimes have been combing the trails around Spider Lake all weekend.

Police are asking anyone who might have seen Leger before he disappeared to contact them.
