As it happens, Port Alberni is apparently distinguishing itself as the crime capital of Vancouver Island and rated among the highest in all of Canada. A look at the Crime Stoppers page paints a picture of petty crimes and burglaries - break and enter, theft from cars etc. Kid stuff primarily, from the looks of things, probably indicative of a drug use issue in that rural community.

According to Hunter’s report, criminal offenses for the quarter were up 17 percent in Port Alberni compared to 2018, and property crime was up 15 percent. Thefts, shoplifting and frauds are seeing the largest increases.
His report also references an increase in assaults but notes that 79 of the 81 cases reported were between people who already knew each other. Of the two remaining assaults, one was between a cab driver and a client and the other between an overdose prevention patient and a volunteer.
So thieving may well be part of the common experience for troubled youth in PA. (Both went to an alternative school where a town's "bad boys" establish a social structure that is not necessarily driven by a need for community acceptance) But physical attacks on strangers is rare to non-existent and the last murder in Port Alberni took place in 1996. I think that may be why a teenaged acquaintance, who has also been following this tragic escapade, tried out his theory on me. He proposed another possibility entirely. His theory is that BS and KM were driving up the highway in the dead of night and saw a van pulled over with the rear doors wide open; a hole in the window and nobody anywhere in sight. Assuming the van was abandoned, at least temporarily, they immediately pulled over and stripped the van of anything they could find of value. In the dark, they never saw the murder victims lying on the ground on the other side of the van. They carried on their way, probably high as kites and camping with their newly acquired gear. But then during the next few days, they learned not only had the van owners been murdered, but that they themselves had been declared missing and so they had no idea what to do, knowing that when they were found there could be questions about the stuff they had stole. They could think of only one thing - they needed a different vehicle in order to stay "disappeared". As for not contacting their families, few teenage time clocks are set to coincide with parental worries. In a month or two they could get in touch, perhaps. And then, stopping at a rest stop, they met an elderly gentleman with a terrific vehicle was parked nearby. He was picking mushrooms or something. Anyway he didn't seem to know anything about their situation. One thing followed another, including a completely accidental vehicle incident took place in which the Professor was run over by their truck, with the unlicensed BS at the wheel. Maybe he was backing up or something. They may or may not have tried to help but then they realized he was dead. What they did do was make another stupendously stupid decision. So they set their "incriminating" truck on fire, stole the Professor's Rav 4 and booted out of there. Is my teenaged sleuth friend's theory reasonable? (I just hope it doesn't get me booted from the forum. Sorry in advance, MODS, if I'm too close to the line.)
