Background
Mustafa Al-Qaysi was convicted of second-degree murder in the October 19, 2019 stabbing death of Justin Turnbull-Greenwood in Windsor, Ontario. Surveillance footage captured the attack at 3:22 p.m. on Tecumseh Road, showing two men exiting a silver Dodge van (owned by Al-Qaysi) and immediately attacking the victim. One attacker (later identified as H.H., a separate co-accused) and another assailant made stabbing motions toward the victim. After the attack, both men fled back to the van and escaped. The only live issue at trial was whether the Crown had proven beyond a reasonable doubt that Al-Qaysi was the stabber, as the Crown’s case rested primarily on circumstantial evidence.
The trial judge relied on eight categories of evidence: surveillance footage showing a van leaving Al-Qaysi’s home 15 minutes before the attack; a video found on Al-Qaysi’s phone from two days prior showing him wearing a grey Roots hoodie with a dark logo matching the stabber’s clothing; white Nike Air shoes found outside his bedroom bearing the victim’s DNA; grey Roots-branded pants found in his home matching the stabber’s attire; evasive driving and flight from police the day after the stabbing (contrasting with prior compliant conduct); and recognition evidence from Jaylah Browne, Al-Qaysi’s ex-girlfriend of five years, who identified him as the assailant in surveillance footage and the rap video. The trial judge found the attack was targeted and planned, with the van driver dropping off the attackers and assisting their escape.
Al-Qaysi’s defence raised several alternative explanations: that friends may have borrowed his van without his knowledge, that H.H. may have transferred the victim’s blood to the shoes when changing clothes at Al-Qaysi’s home after the stabbing, and that he may have been the driver rather than the stabber. The trial judge rejected these theories and convicted Al-Qaysi of second-degree murder.
The Court’s Holding
The Court of Appeal for Ontario, in a unanimous decision by Justices Rouleau, Miller, and Paciocco, dismissed all grounds of appeal and upheld the conviction. The court acknowledged that the trial judge misapprehended the defence position regarding whether Al-Qaysi could have been the driver—the judge stated the parties agreed he was not the driver when, in fact, defence counsel only argued it would be speculative to make that finding. However, the court found this misapprehension was not material to the conviction because the trial judge’s verdict rested on eight independent categories of affirmative evidence establishing Al-Qaysi as the stabber, not on his elimination as the driver.
Regarding the shoe evidence, while the trial judge did not explicitly address the blood-transference theory (that H.H. deposited the victim’s blood on the shoes when changing clothes), the court found the reasons were adequate when read in context. The trial judge explicitly rejected the transference theory during oral submissions and made clear findings that the victim’s blood got on the shoes during the attack itself, given the proximity of the stabbing scene and the victim’s profuse bleeding. The court noted the trial judge posed extensive questions to ensure he understood defence counsel’s position and clearly indicated he was not persuaded the transference theory was reasonable.
On the alternative-inference argument, the court clarified that Villaroman does not require courts to treat every individual piece of circumstantial evidence as if it must be consistent only with guilt; rather, it requires judges to consider whether the totality of circumstantial evidence can support an inference other than guilt. Here, the cumulative weight of evidence—the matching clothing, DNA on shoes found at his residence, recognition evidence, the video of him in similar attire, and his flight from police—supported the conviction. The court also found no reversible error in the trial judge’s treatment of Ms. Browne’s recognition evidence, despite finding her to be a “dangerous Vetrovec witness” with credibility issues; the trial judge assigned it “some weight, albeit small” and applied appropriate legal tests for recognition evidence reliability.
Key Takeaways
- A trial judge’s misapprehension of a party’s legal position (whether evidence should be admitted or what the defence is arguing) is reversible error only if it causes a misapprehension of the evidence itself and plays an essential role in the conviction; peripheral misapprehensions do not warrant reversal.
- In circumstantial evidence cases, courts need not explicitly address every defence theory raised if the affirmative evidence supporting guilt is so strong that alternative explanations are clearly rejected; adequacy of reasons is assessed functionally in context of evidence and submissions.
- The Villaroman principle requiring consideration of alternative inferences applies to the totality of circumstantial evidence, not to individual pieces of evidence, and judges retain discretion to weigh the probative force of each item.
- Recognition evidence from a witness with significant credibility problems may still carry some weight if the judge applies proper legal tests and the person is identified across multiple reliable sources (video, clothing, DNA, surveillance footage patterns).
Why It Matters
This decision clarifies important boundaries in appellate review of circumstantial evidence convictions. It establishes that minor misapprehensions of a defence position do not warrant reversal if the conviction is supported by independent affirmative proof, and it rejects a narrow reading of the Villaroman principle that would require courts to treat each piece of circumstantial evidence in isolation. The decision also reaffirms that trial judges have flexibility in explaining their reasoning; they need not address every alternative theory explicitly if the cumulative weight of evidence and their express rejection of key defences makes their reasoning path clear from the trial record.
For criminal practitioners, the decision underscores the importance of making explicit admissions or formal agreements about contested facts if seeking to narrow the trial judge’s inquiry, since ambiguous submissions or mere argumentative positions will not be treated as agreements. The decision also demonstrates the enduring strength of DNA evidence combined with corroborating circumstantial evidence—clothing, identification, and post-crime conduct—even where recognition witnesses have credibility concerns.
