Mounties found Jeffrey Cooper dead in a Forest Service Area about 112 kilometres south of the community of Houston on May 26, 2014.
Cooper was in the area hunting grizzly bear, and police have said previously that the resident of Tuttle, Wash., was being assisted by guides.
RCMP Cpl. Dave Tyreman said the major-crimes unit assisted Houston Mounties in the complex investigation and forwarded a report to Crown counsel.
Tyreman said prosecutors have reviewed the evidence and decided not to approve charges.
Houston is located nearly 1,100 kilometres north of Vancouver.
