Detective Backus

Two appellants were convicted of murder arising from a shooting in Toronto allegedly motivated by street gang rivalries.

The appellants appealed their convictions on four grounds: (1) the trial judge erred in admitting expert opinion evidence on street gangs from a Toronto Police Service detective; (2) the trial judge erred in admitting handwritten rap lyrics seized from an apartment; (3) the trial judge erred in instructing the jury on eyewitness identification evidence; and (4) the trial judge's conduct gave rise to a reasonable apprehension of bias.

The Court of Appeal dismissed all conviction appeals and the sentence appeal, finding that while the trial judge committed an error in principle regarding expert evidence bias analysis, the evidence was properly admitted.

The court also found the jury instructions on eyewitness identification were adequate and fair, and that the trial judge's conduct, though at times harsh, did not demonstrate bias when viewed contextually.

The appellant was convicted by jury of second degree murder in the shooting death of a drug dealer.

He appealed on two grounds: (1) that the trial judge erred in rejecting evidence regarding an alternate suspect, and (2) that the trial judge erred in instructing the jury on party liability through aiding.

The Court of Appeal upheld the conviction, finding that the trial judge properly excluded the alternate suspect evidence as lacking sufficient probative value, and that while references to aiding may have been unnecessary, the jury charge read as a whole would not have misled the jury regarding the requirement that the appellant be a principal or joint principal with the requisite mental state.
