(Not sure whether this is best in IMHO, CS or MPSIMS, so here.)
I freely admit this comes from reading too many short-crime-stories-with-a-twist, but I’d appreciate a reasonably serious and grounded discussion.
So Mr. B disappears. No body is found, but copious evidence points to Mr. A having done away with him. A is convicted of the murder and sent to prison.
Mr. A gets out after 25 years, and one day there’s a knock on the door - it’s Mr. B, who is laughing because he not only slipped away to a new life and identity, but managed to set up his old rival in the process.
In a fit of rage, A kills B.
So… what crime is A guilty of? What approach would a reasonable DA take to the case? (Conviction, but with time served?)
(Of course, the real solution would be for A to bury B in the basement and forget about it, but it’s possible someone might come looking for Mr. B-prime.)
And… didn’t something like this happen in reasonably recent history? Maybe LA gang related?
More like a 1999 movie, actually. But double jeopardy wouldn’t apply. You can’t be convicted for the same crime twice, but it wouldn’t be the same crime. You’re talking about a different murder under different circumstances.
This issue came up once on Law and Order, IIRC, but I couldn’t find the episode.
Getting back to Mr. A: of course he’s guilty of murder, but I suspect that with a good lawyer and the right jury, he’d be found guilty of a much lesser charge. A DA might be inclined to let him plea to a lesser charge rather than risk an embarrassing trial, especially if he was the one who tried him originally for murdering Mr. B.
This was part of the plot of the first episode of Crazy Like a Fox.
I would say “voluntary manslaughter” - it’s not the same crime as the one for which Mr. A was convicted; among other things, it happened at a different time. Of course, Mr. A has a case for wrongful imprisonment.
