Vern Boettger from the small community of Vavenby, about 150 kilometres north of Kamloops, hasn't been seen since last Oct. 6.
The RCMP says Boettger was last seen in his pickup truck.
Sgt. Kevin Podbisky says search-and-rescue crews from Kamloops and McBride have been called in to help the searchers from Clearwater who have already been on the case.
Podbisky says the search has been expanded, but so far there's been no sign of Boettger.
