The wide disbursement of evidence appears brazen and bizarre, but should not be interpreted as some sort of affront to citizens-at-large, said Neil Boyd, a criminology professor at Simon Fraser University in Vancouver.
He suspects whoever was behind the crime was merely trying to cover tracks with whatever tools were at hand.
"It's difficult to get rid of bodies. How do you do it in a place like Toronto? You don't have access to heavy machinery and can't bury them 30 feet underground," says Boyd. "Of course, by definition all of this is extremely risky and displays a kind of contempt for human life that almost all of us find very disturbing."
Arntfield agrees, adding that he suspects the planters were used as interim storage, and that police would find more victims at an intended interment location -- wherever that is.
Yaksic diverges from Arntfield in deeming the killer a psychopath, in part because of the extreme measures taken to hide evidence.
"I sense that there is some type of trepidation in their life where they think that they're going to be caught, whereas other killers are arrogant and very confident in themselves," he says.
