A Saskatoon courtroom erupted into emotion Wednesday afternoon during graphic testimony at the Douglas Hales murder trial.

Hales is charged with first-degree murder in the death of 25-year-old Daleen Bosse of Onion Lake Cree Nation who was last seen in May 2004.

The outburst included a woman throwing a shoe directly at Hales that was blocked by a court officer.

The woman was restrained and removed from the courtroom and the trial took a short recess.

Friends and family of Bosse were reacting to an audiotape in which a male voice describes in detail her murder to an undercover police officer.

The recording was made in July 2008 and is the first of a few murder confessions Hales allegedly made to an undercover police sting operation.

Earlier in day, court also heard Hales displayed racist, sexist and sadistic attitudes early on in the undercover police operation.

A second RCMP officer involved in the Mr. Big operation told the court his role was to portray himself as an uneducated, violent and racist criminal with negative attitudes toward women.

However, the officer said Hales needed little prodding to show his true colours.

He said Hales repeatedly voiced his dislike of Aboriginal people, at one point referring to First Nations people as “zombies.”

Hales also talked a number of times about his frustration with his common law partner saying he would like to strangle her to death on more than one occasion.

Another time, he professed his admiration for B.C. serial killer Robert Pickton.
