Just noting something that can up in the article that we have discussed: "Gone were his wallet, keys, sunglasses, and county-issued laptop, which police would later say he took from home minus its case and power source." BBM
The reason they believe this is that LE has a witness that saw RFG in Lewisburg win the Mini doing something with the laptop. The witnesses reported prior to public disclosure that the laptop was missing, which was late in the week.
Now, that is only strong evidence that RFG took the laptop with him. It could play into suicide or walkaway. We also know of long term interest on RFG's part to get rid of the data on the laptop. I would submit that, if he was planning to be in Lewisburg, he might have decided it was a good spot to dispose of it, even if he planned to return home. It would not preclude foul play, as it could have been a coincidence. In other words, he could have planned to go to Lewisburg for some other reason and decided that it would be a good place to toss the laptop.
