Court heard Thursday police investigators were on scene and analyzing the site of the burned remains of Daleen Bosse within hours of Douglas Hales leading undercover officers there.

Hales is on trial for first-degree murder in the death of the 25-year-old woman from Onion Lake Cree Nation who was last seen in May 2004.

Once the undercover RCMP officers knew the exact location of the remains, Hales was promptly put on a flight to Vancouver so investigators could return to the scene for further analysis.

University of Saskatchewan archaeology professor Ernie Walker led the investigation in a remote wooded area near Martensville on August 7, 2008.

Walker is well-respected forensic expert who has assisted police in several murder investigations.

He told court much of Bosse’s remains were intact including vertebrae and part of a skull cranium.

Walker said the site had largely been undisturbed since the fire had occurred about five years ago.

He said he was able to identify the remains as those of a female about 25-years-of-age.

Walker added it is virtually impossible to generate the necessary heat to completely incinerate a body in an open-air fire.

The Saskatoon trial has now adjourned for the week and will resume again on Monday.
