A DNA match links a suspect to a bloody knife used in the killing of Tori Dunn, according to expert testimony provided during a second-degree murder trial on Thursday. Forensic evidence presented in a Surrey court connects Adam Mann to several items found near the crime scene where Dunn was stabbed in 2024.
What did the forensic evidence reveal?
Janny Lau, a forensic biologist from the National Forensic Science Laboratory, testified that DNA samples from multiple locations match the defendant. The evidence presented to the court included:
- A large kitchen knife found near the scene, which contained a mixture of DNA on the handle that is 280 trillion times more likely to belong to Mann than a random person.
- A grey hoodie found near the residence, with DNA on the cuffs potentially belonging to both Mann and Dunn.
- A mobile phone belonging to Dunn, which was recovered from a nearby grassy area.
Lau stated that the probability of the DNA on the phone matching Mann rather than a random individual is between 12 billion and 17 billion times.
Challenges to the DNA evidence
Defense lawyers questioned the reliability of the DNA databases used by the Royal Canadian Mounted Police. In response, the expert noted that investigators have transitioned to using a stratified database that covers various ethnicities. This updated analysis yielded results similar to the original findings.
The prosecution expects to finish presenting its evidence by midday Friday. Meanwhile, the defense indicated they require more time to consult with the defendant regarding next steps in the proceedings.
