Wow Sherlock - can you fit this into the timeline regarding the known points?
Boat Ramp 3:40ish
Rock Island 5:40ish - how much longer to CB from this point?
With flow of moderate traffic at that time of day, based upon times I've driven that way, I'd say 10-12 minutes to the turnoff from the highway to CB. Another few minutes to get to the property. So 15 minutes or so is a good estimate, I'd say- either way, coming or going
What if the perp was leaving CB and heading for the canyon? How much time to get to the approx. place the car was left?
OK, I'd say about 15-18 minutes from the dam to the Columbia River Bridge in South Wenatchee, then 15-20 minutes to spot on PC road if traffic is fairly busy. Between 4 to around 6 the traffic on the west side of the bridge can be pretty busy. Maybe add in a few minutes - say 5- to the spot where the car was found as I doubt anyone would drive too fast as to bring too much attention.
So it would likely take 35-43 minutes to get the car where it was found at PCR
Thanks,
Salem
