Forensic expert testifies at murder trial of Robert Stephen Wright as to how DNA could have been transferred to Sweeney’s body on the day she was killed
A forensic scientist with a specialty in DNA transference testified on March 10, in the second-degree murder trial of Robert Steven Wright.
The DNA associated with these clippings include two pieces of evidence that were a part of testimony on March 9. Manager of the biology section at the Centre for Forensic Sciences in Sault Ste. Marie, Tara Brutzki testified yesterday that she tested the many pieces of evidence from the Sweeney case during a full case re-examination she performed in 2013, when new technology had become available.
Today Dziak went into further detail on the difference between minor and major, and the ways that the DNA, in this specific case, may have transferred onto Sweeney’s body. An example of direct contact, she testified, would be a person who cuts themselves and then another person, perhaps their partner comes to them and the blood then transfers onto the other person.
She was asked to create a letter of opinion for the Crown, based on her expertise, to consider two alternative propositions based on the fingernail DNA evidence: was the DNA found associated with Sweeney’s fingernails deposited through close physical contact, a direct or indirect deposit of DNA at the point of contact of the nails — not any part of her, just contact with the fingernails — with some degree of force, or; the DNA was deposited through everyday casual contact.
“That is also a possible explanation,” Dziak testified. “However one of those scenarios is not more likely than the other.” Lacy asked about preventative measures and protocols at the Centre for Forensic Sciences to avoid contamination, and if they had ever failed.
