Further tests are required to determine the cause of death and identification of a body discovered by two tourists in Banff National Park earlier this week, the Calgary Medical Examiner's Office said Tuesday.

In a release issued Tuesday, the RCMP said the body of a man was found around 11:45 a.m. in Louise Creek, about 2.5 kilometres south of the town of Lake Louise.

The RCMP said in that the deceased has been tentatively identified, based on evidence found at the scene, as a Caucasian male in his late 30s from Regina.

The office conducted an autopsy Tuesday but said in a release that a positive identification had not been completed.

The office said further physical examination and toxicology tests would be needed to establish the cause of death. It was not known when these results would be available.

The RCMP said there was no indication the man was attacked by an animal. They are treating the death as suspicious.
