Again, I have 100% respect that you live in Truckee and that you drove down the road Kiely would have driven, and that the road was treacherous, so you don't think Kiely drove herself there.
I'm still unclear, though, on what you think did happen. I know you say you're believing it's foul play, but I'm confused about the logistics.
The road is extremely difficult to navigate, even with your AWD and even at 5 mph, even in the daytime. I hear you. I understand. But how would the scenario you envision here actually happen?
If someone else drove Kiely there, with murderous intent, how did that person get down the impassible road? How could he (I presume a male) have driven Kiely over that terrible road, gotten the car which you speculate he drove with her into the lake, when he was allegedly driving it, and then "go home in <his> own car?"
If I'm reading it correctly, it would be impossible for someone to not only traverse a treacherous road, but to drive it into the lake while he himself is behind the wheel, leave the car with Kiely in the lake, and yet take his own car home down that road.
Are you thinking therefore that more than one car made this deadly trip? An accomplice that followed them and then drove the culprit back?
I'm not meaning to come off as argumentative, at all, I just can't grasp the logistics. If it's a road that is a menace to a car, it's even more difficult for me to imagine two cars taking that trip.
Only my own opinion and I know I don't live there. I am truly just inquiring.
