Missing a few steps silly, consume the fleshy bits leaving just the bones, grind up the bones or burn then into ash and take them somewhere (water preferably) and throw it into the wind, and keep the teeth so you can start making jewelery out of them and start a side business making profit from the murders, and if you target people who in the lower class of society that nobody will look for like homeless people or elderly folk in elderly housing, no one will look for them and the meat just falls right off the bone
