Answer: The best way to dispose of a body is to fed it to pigs. they eat everything. Teeth, nails, etc w/o leaving any trace at all. Or if you want to be really crafty you could mix chemicals into a bathrub/plastic bin that disolves everything into sludge and dump into a drain or river. But the ONLY way to kill someone in 2020 w/o getting caught is to kill someone completely random. Someone you've never spoken to at all. good luck lol
