DNA evidence linking Adam Mann to a bloody kitchen knife was presented Thursday in the second-degree murder trial of Tori Dunn at the Supreme Court in New Westminster, British Columbia. Mann is accused of killing Dunn during a June 2024 break-in at her home in Surrey's Port Kells neighborhood.
Forensic Expert Testifies on DNA Findings
Janny Lau, a forensic biologist with the national forensic laboratory, told the jury that a large kitchen knife found near the crime scene had blood on its blade that was highly likely to be Dunn's. The knife's handle contained a mixed DNA profile from three people. When compared with Mann's known sample, the probability that one component came from Mann rather than a random individual was 2.8 quadrillion times greater, according to the testimony.
A gray hoodie discovered near Dunn's residence also yielded two DNA profiles on its cuff, possibly from Mann and Dunn. Dunn's boyfriend had previously testified that the attacker wore a gray hoodie. Additionally, Dunn's missing phone was later found in nearby grass, and DNA on it matched Mann with a likelihood 12 billion to 17 billion times greater than a random match.
What Did the Defense Question?
Defense lawyers challenged the Royal Canadian Mounted Police's use of a DNA population database. The expert said police have since re-analyzed the samples using a stratified database that accounts for different ethnic groups, and the results were similar to the original findings.
The prosecution is expected to finish presenting its case by noon Friday. The defense said it needs more time to consult with the accused.
