The family members of a missing elderly couple say they will continue to search for Lyle and Marie McCann until snow hits the ground. The couple's family launched their own investigation this weekend looking for evidence that will lead to a break in the case.

On Saturday, a ground search took over the area around Nojack, located about 150 kilometres west of Edmonton where the McCann's burned-out motorhome and SUV were found on two separate occasions in July.

Searchers scoured the land on ATVs , looking for anything that could lead to the whereabouts of Lyle and Marie whop have been missing since July.

Among the searchers was the couple's 14-year-old great nephew.

"If I were in their position, I'd rather have people looking for me than sitting at home," said John McCann.

The teen says he feels positive that they will be found.

Up until recently investigators asked the family to hold off doing its own pursuit.

The couple's son Bret describes the past few months as a nightmare.

"You can just imagine how difficult this is, like, where do you start looking? It's like looking for a needle in a haystack," he said.

Family members say they hope to continue their efforts for as many days as possible before the snow hits.

The search comes one weekend after RCMP executed a search warrant on a private property in the area. Officials have not said if they found any key evidence, but confirmed no bodies were recovered.

Travis Vader is the lone suspect named in the case.

A Crime Stoppers award that leads to the whereabouts of the couple stands at $60,000.
