With the new information; Bow missing, bullet holes in swapped tires and Bob's hubcaps, and Randy's mom calling Bob's family:
6) What are the odds that 2 people from the same family would be murdered(as it now looks for Bob) a few years apart? This is statistically significant, and if nothing else, points to something going on in the family environment. Both Bob and his sister had exceedingly bad judgement and become victims? There is more to the associations involved with these people than a clean cut graduation photo. While there may be no direct tie with the bikers, there is some other thread here that caused these 2 people from the same family to be involved in risky circumstances. There has to be more info to get a Picture of Bob and what he might of have done for example: a) what if he was confronted by a group of people, on foot or in a car? b) How likely would he have been to pick up hitchhikers? c) what is the possibility that he was more interested in pot or drugs than deer? d) how reliable was he at showing up on time, etc...?
7) Exactly why was his sister murdered? We know it was bikers, but was a reason given? Earlier, think someone said she was an informant. This strikes me as strange. Girl hangs around with dangerous bikers and then squeals on them. That's playing with fire. If Bob's sister had those kind of balls, one wonders what Bob was capable of. Or was she having no fear of death because of her missing brother? Psychologists, help me out here.
Snipped by me. From an article I linked early on, it states that his sister died in a fire at a bar. Later, it was found that the fire was started by some bikers and they were found guilty of her murder. For all we know, she was a totally innocent person in the wrong place at the wrong time. She might not have even SEEN her murderers. The bikers might not have known that she was even in the bar. Since LE thinks that there is no connection between Bob's disappearance and (years later) his sister's murder, I think that is a strong possibility that they are not linked.
Also in the earlier writeup- it was noted that Bob had been to Randy's house numerous times and was familiar with the area. So if he was to go to Randy's house, I would imagine that the witness sighting would suggest that Bob was meeting someone else or very confused. MOO
