Calgary triple murder trial hears DNA found at suspect’s farm
DNA evidence was found on a hacksaw, meat hooks, rubber boots and in a piece of biological material recovered from the property of a suspect on trial in the deaths of a couple and their grandson, court heard Tuesday.
Douglas Garland, 57, is charged with first-degree murder related to the disappearance of Alvin and Kathy Liknes and five-yearold Nathan O’Brien from their Calgary home in June 2014.
The child’s mother testified earlier in the trial that she found pools of blood when she came to pick up her son after a sleepover with his grandparents following their estate sale. But the Likneses and Nathan were gone.
RCMP forensic expert Vivian Mohrbutter testified Tuesday that there was DNA evidence from all three in the home. Swabs of blood were taken throughout the home, from a 45-pound dumbbell found in the garage as well as from outside on a sidewalk.
Mohrbutter said that was also the case at the Garland farm near Airdrie, north of Calgary, where DNA from the adults and the child was found on a pair of rubber boots.
“The profile obtained was determined to be of mixed origin consistent with having originated from at least two individuals. The profile of the major component I determined matched the ... known sample from Nathan O’Brien,’’ said Mohrbutter.
