you hide there body in a bag with you out 8feet underground and at 6 feet put a deer or cow cover with dirt and at the 3rd feet mart put a small anime like skunk or something and if you get questioned by cops just don’t talk and get a lawyer or make up some lie and if the person when missing at night say you were asleep and if they went missing during the day say you were at home or doing something with a friend that can vouch for you
