I'll start by breaking his neck, I'll be sure to wear gloves to leave no prints, just for insurgence purposes. Afterwords, I'll burn the gloves and spread the ashes across the land. I'll get rid of the body by first chopping it into smaller chunks, grinding it up, bone and all into a fine paste, I'll visit a local farm I've payed in advanced to let me dispose the remains of the body by mixing it in the pig food, the pigs will eat the remains mixed with their food and their stomachs will digest everything else, so broken down no one will ever find the remains as it's is mixed into the land.
