Saskatchewan’s highest court has dismissed the appeals of three men convicted in a 2006 shooting death during a home invasion in Regina.

Jacob Worm was sentenced to life in prison with no eligibility of parole for 16 years for second-degree murder in the death of 48-year-old Douglas Anderson.

His brother, Tyrone Worm, and their cousin, Denny Jimmy, were both found guilty of manslaughter in connection with the slaying, and were each sentenced to 12 years.

All three appealed their convictions, on the basis that the trial judge had erred in her instructions to the jury. The Worm brothers also argued they were inadequately represented by their respective lawyers at trial.

However, in a decision released Tuesday, the appeal justices said the trial judge had properly instructed jurors. The court also found there was insufficient evidence of incompetence on the part of lawyers for the Worm brothers.

In November 2006, the three men broke into a home they mistakenly believed was a drug house operated by the rival Native Syndicate gang.

The men demanded drugs or money before Jacob Worm, armed with a handgun, fatally shot Anderson in the stomach in front of his family.
