leaving the gun behind can often leave them with more questions than answers....which for the Shooter is always a good thing

I agree with GreenWolf on this one. Poison is the way to go, no noise no weapon or casings or bullets to trace. And if no ones around put the body in a rubbermaid trash can and then dump it in a lake or ocean. Those things will sit for a thousand years and never deteriorate.

piano wire...

Most peope are not aware, that when disposing of a body in water, it takes weight of roughly 2/3s the victims weight to keep it on the bottom once the decay gasses get going.

Also, several punctures (for outgassing) are a good idea.

At least that's what I've heard.

"..The new Judge is interesting, because if you use the shotgun rounds for it like buck shot, #4, and #6 shot (if vic is closer than 5 feet), there is nothing to trace back to that gun..."

I've got one.
