Grant’s link to Derksen ‘bad science’: expert

Winnipeg Free Press Canada
The first-degree murder trial for the accused killer of Candace Derksen wrapped up its fourth week of testimony Friday with an expert witness’s condemnation of the science used to link Mark Grant to the death scene.
McMaster University genetics professor Dr. John Waye said “bad science” was behind some of the DNA analysis done by a Thunder Bay lab that linked biological material found at the scene and on Candace’s clothing to Grant.
