In a first‑degree murder trial, the Crown sought to introduce evidence of prior discreditable conduct arising from Blackberry Messenger chats and related events, including possession of a stolen vehicle, a cheque‑cashing fraud, a concurrent plot to rob and kill another individual, and evidence relating to the accused’s financial misrepresentations.
The court considered the governing principles for admitting prior discreditable conduct, requiring a link to a live issue and a probative value that outweighs prejudice.
The court admitted evidence relating to a stolen vehicle, a cheque fraud shortly before the murder, efforts to obtain firearms, and chats revealing a concurrent plot to rob and kill another individual because they were intertwined with the narrative and relevant to motive, planning, deliberation, and state of mind.
However, the court excluded certain other evidence, including a photograph involving an imitation firearm, related web searches, and earlier unrelated robbery‑murder planning discussions, finding their prejudicial effect outweighed their limited probative value.
Evidence concerning the accused’s financial misrepresentations was admitted as relevant to motive.
