I see a lot of comments to the effect that the actual perp ( Remember innocent until proven guilty ) in Idaho "wasn't the first go-round".
I thought this YouTube, which starts slowly on the his theory, presents the theory that 3 more murders could be connected to the suspect, including the 2 in the general Portland area.
Would be interested to know the suspect's whereabouts during them. Credit card receipts, cell phone pings, etc.
