You cut the body into sections and put them in black plastic bags, take a boat out, and
dump the bags into the ocean where a current will take the bags all the way up to Greenland.
First you have to dismember the body, and then put each body part in concrete. Then borrow a boat and drive as far as you can away from land and drop each concrete block into the ocean so it will sink to the bottom and stay there. Hehe.
