You don't do it at your place - you go into the middle of nowhere. The GPS location will save to the cloud, but by the time anyone gets there, days, weeks, months after his disappearance, all evidence will be gone. Just make sure you use an old van without GPS to do all the transport - one of those rent a wreck things rented with a false ID for cash while wearing platform shoes, padded clothing, wig, facial disguise and a hat, but nothing too wild or memorable - just enough to throw off identification without being noticed much, if at all. Should be fine.
