The RCMP are investigating the discovery of human skeletal remains found in a remote bush east of the Pembina River, near Westlock.

Police say the remains include a skull and some other bones that had been exposed to the elements for more than than two years and had been scattered by animals.

The remains have been examined by Edmonton's chief medical examiner's office and are believed to be those of a First Nations adult male in his 40s, Westlock RCMP said in a release. The cause of death has not yet been determined.

Hunters discovered the remains last week in a remote area about 10 kilometres northwest of Westlock.

Police are treating the case as a suspicious death.

The Westlock RCMP are not currently involved in any unsolved missing persons investigations.
