Double Jeopardy?
<p>A woman is <em>thought to have been</em> murdered (corrected this first sentence from a previous comment). A man is arrested for it. He is offered a plea bargain deal that will get him 15 years or he can take his chances in court but would get life if found guilty. All they have is circumstantial evidence but the arrested man is convinced by his lawyer to plea bargain due to the overwhelming circumstantial evidence against him.   (side-note: For this scenario, the man did NOT actually murder this woman as we find out later in this story but he just didn't want to take the chance of getting sentenced to life in prison).  Man serves his 15 years and is released...no probation, he served his entire sentence.  Knowing he did not murder this woman he looks for her after he is released and finds her.  Ends up she wanted to disappear and start a new life and set this man up to be framed for her murder.  He is obviously mad at this woman and after he finds her, he kills her for revenge of sending him to prison and losing 15 years of his life for something he didn't do.  He is arrested again and admits to the police to killing her but does not worry about being charged for murder because he has already been convicted of her murder and served his sentence. Can he be charged, convicted and sent to prison again?  </p>

<p>Yes, because the crimes are different instances. Let's remove the guilty plea and the fact that it is murder: can a person assault a person, be tried and imprisoned, then assault the same person later – and get off by declaring "Double jeopardy!". No, it's not the same crime. It's the same type of crime, and involves the same victim, but it is still a different crime. The same with your proposed scenario. (Incidentally, your first line is wrong: the woman wasn't murdered, she was <em>thought</em> to have been murdered).</p>

<p>This is the premise of the movie Double Jeopardy (1999), and it has already been debunked by Alan Dershowitz (among others):</p>
<blockquote>
<p>Mr. DERSHOWITZ: No. It wouldn't work at all. Look, any lawyer could make the argument--25 years ago, I appealed a case and I actually won it. A guy tried to shoot somebody who he thought was alive, but was actually dead. And the court ruled that man dies but once and acquitted my man of murder charges. But today, the law on double jeopardy has become very restrictive. It has to be the same transaction. The same event. It even has to be in the same state.</p>

<p>Not double jeopardy, the man will have pleaded to having killing someone on a particular date (or possibly date range) in a particular manner for a particular reason.  That will be the crime he was in jeopardy for and that jeopardy will be over.</p>
<p>Let’s take a look at a slightly different scenario, the man is a serial killer and confuses the details of two victim’s (S and A). He is tried and pleads guilty to the killing of victim S on a Monday by strangulation, evidence later comes to light that he in fact killed S on a Friday by stabbing, and it was victim A (then unknown to the authorities) that he killed on a Monday by strangulation.  Arguing that he can’t be tried for the second murder isn’t going to fly.  Different circumstances, different crimes.  They would amend the name of the Monday victim, but just for accurate record keeping reasons (and family sensitivity), not because it was necessary in order to try him for the killing that took place on Friday.</p>
<p>That argument would have never been accepted, the state doesn’t owe him a free murder.</p>
<p>He could have been convicted of killing a person that never existed, would you expect him to be able to kill one person for free if it was proven that he falsely confessed?</p>
<p>In point of fact, not only can he be tried and convicted of the murder, he can be convicted of perjury for his false plea.</p>
