All theoretical of course but based on a scene from a movie that I wonder if it’s based in real life.

Let’s say John kills Jane and the police come to the door for an investigation and the police ask (pre Miranda) do you know what happened to Jane? And the guy says “yes I killed her with a knife in my kitchen and buried her body at the pond”

So police arrest John and go to the pond and find the body

Would the evidence have to be thrown out? It is pre-arrest so that’s where I think the water is murky in terms of legality, but it is during an investigation

So could they still charge with murder but can’t use the wbody, weapon, or the statement for evidence? Would the case only rely on other evidence?
