Do not piss off a bunch of farmers...like a friend's dad used to say.
"I've got 40 acres and a backhoe, how far do you want to take this?"
I always make jokes about taking someone out "pig hunting".
It works in reverse, you shoot them in an area where you know pigs frequent.
When the pigs find their body, they will eat everything, leaving at most, a few scattered teeth and hair.
If you can find and collect those, there's no forensic evidence left behind.
