How do murder without getting caught?

were you gonna hide the body is important ok if by knife poison need to erase the tracks

puncture the lungs before throwing it to a river so that the body will not float. Cuz the body will sink after water replaces the air inside the lungs HAHAHAHAHA

Inject 200-300ml of potassium under their tongue so they can’t find the injection mark and when they die the potassium will evaporate into their muscles so there will be no substance found when examining their body and will die by cardiac arrest

wait i forgot something no witness wear gloves always make sure that you have a location of where you where and somebody who can say you was with them ok plus you need to make sure who you work with don't sell you out dead corpse's don't speak

kill using an icicle bc the evidence will melt and your finger prints will forever be gone. then (like some other comments) puncture the lungs so the body will sink, if ppl do find it, they'll mostly rule it out as suicide, if not, then they won't trace it back to you ヾ(❀╹◡╹)ﾉ~
