What do you think are the options for the car at this particular parking lot? Also is it fair to assume there were no security cameras?
So the options for car are either:
1: Ray drove it there
-to go antiquing and something happened to him, foul play
-to meet someone there, disappear
-to commit suicide either via river or ?
2: someone else drove it there
-to stage the scene to appear to be any of the above
There were no security cameras at the Street of Shops (SoS).
Except for something random, antiquing is unlikely. The killer, "K," would either had have to known that RFG was going antiquing or followed him.
There is no suggestion that RFG had planned to go antiquing specifically, and he did not go the SoS immediately, according to the witnesses. He would have had to told someone that he would be at the SoS, and not tell his girlfriend.
The route RFG took was rural and it had some long strait stretches. It would be difficult to follow RFG without him noticing him. As noted above, he didn't go their directly, and it would be difficult following him around Lewisburg for the amount of time that the witnesses put him there. He was also known to have drive very fast, which would mean that the tail would have driven equally fast.
IMO, your first point under one can be ruled out. However, all of that would
not rule out meeting someone in Lewisburg, a clandestine meeting. Whomever he met, under this scenario, could be K. K might not have even set out to kill RFG.
The second has a lot of evidence against it. Someone who recognized RFG, a "county worker," saw him turning on 192 at Centre Hall. Another witness who recognized him, at the time, saw him in Lewisburg between 4:00 and 5:00 PM, going south on Route 15, north of Lewisburg. His scent was detected by tracking dog in the parking lot, where other witnesses saw him inside the Mini between 5:00 PM and 5:30. Again, someone else driving the Mini
to Lewisburg is, IMO, impossible. That does
not preclude someone else driving the Mini
after it arrived in Lewisburg.
