Defence in retrial for suspect in Winnipeg teen’s death questions DNA evidence
WINNIPEG — Defence lawyers for a man accused of second-degree murder in a teenage girl’s death in Winnipeg more than 30 years ago have questions about DNA evidence.
Mark Grant is being retried in the slaying of Candace Derksen, who disappeared on her way home from school in November 1984 and was found frozen to death in a shed about six weeks later.
A former police crime analyst told court that early tests done in 1996 found unidentified male DNA on some gum.
John Burchill testified that more advanced DNA tests in the early 2000s found two different male DNA profiles on the gum.
