Not that a whole lot makes sense to me in this case, as eloquently summed up in Snoopter's post on the previous page, but THIS is now what is playing on my mind. Hopefully someone is more well read on this and can help me out! 
- The location of the car: seemingly parked in a lay by - was this lay by up in the mountains, or heading away from the campsite into a city/town nearby?
- It looks as though the BMW was bay-parked into the lay by...could the killer have been waiting and held them at gun point whilst telling the driver to pull over?
- If the neighbours were saying the Al-Hilli's trip was spontaneous/a bit 'hush hush' then who would have known they were going on holiday, let alone where exactly they were going? I know from personal experience most people let their neighbours know when they are off because of pet feeding/keys/watching the house etc, but would anyone who wanted the family dead know they were going? Especially if, as reports have alluded to, Saad and his brother were somewhat estranged
Sorry for the ramble. But if anyone can help me paint a clearer picture of the car/where they were off to I'd much appreciate it!
ETA: What are people's theories - do you think they were followed, or do you think the gunman lay in wait?
