Hey basecamp, if I have been told the correct version of the story, it was simply somone trying to turn their 4wd around in the wet in the campground and got stuck.
The 4wd was sliding towards a parked car as they where trying to get it out.
The bloke who's car was about to be hit was trying to help and was crushed (not badly) between the 4wd and a tree.
Now, one of the parties in the 4wd is an aquauntance (even that is pushing the friendship) and that is where I'm getting the info.
Knowing this person as I do, there would be a lot more to the story, and I wouldn't be far off I reckon making the assumption they were being knobs in the campground.
Hence trying to find out any more info.
It would have been either Friday or Saturday afternoon or night.
