I found out that you can buy piranhas as pets and i thought out a plan of how you could fill like a pond in your garden with them, push someone in, and then just clean out the pond after each one :/ Too bad I have no one to kill
The trick is, if you bury the body, do so vertically. X-ray scans will easily identify the silhouette of a horizontal body. Also, bury it deep, and place a dead dog a foot or two above the body. If dogs are used to pinpoint the corpse's scent, the police will usually stop after finding the dog, figuring that's what their dogs smelled.
Don't ask me how I know this.
