Caporegime
It's all these witnesses!
And then the witnesses of the murders of the original witnesses, and so on and so forth, and before you know it there is a TV documentary about you. I feel you bro.
It's all these witnesses!
I'd post in GD
Also, what have you done to Scorza?
Sell the body to someone with a kebab van, I'm sure they'd happily serve it up, and the people that bought it thinking it was a standard kebab would just say "mmm, tastes like chicken"!
Break into a pet cemetery and use their incinerator. If you have murder hanging over you, breaking and entering is nothing
For a start, I wouldn't post my plans up on an internet message board using an account from which I can be identified, and from my home internet connection!
Burial at sea. A bit of chain around the body, go a mile or so off shore and off they go. They'd never be found.
Make sure you slash open the abdomen first, it's an air filled cavity (with air filled stomach/intestines and access to the chest area etc) whose buoyancy (if sealed) will always attempt to counteract whatever method of "weighing the person down" you use. So just in case your "weigh-down" fails, make sure the buoyancy is removed first.
