Having now had the time to look through some case books left over from law school (apparenlty the are good for something other than doorstops!), here’s what I have unearthed (a good word considering the amount of dust on this baby):
One of the main issues here is impossibility. I think we can all agree that it is impossible to kill a dead man (or a mannequin for that matter, and if someone brings up that stupid movie…). Impossibility breaks down into two categories, legal impossibility and impossibility in fact.
Cases which fall under legal impossiblity generally hold that it was legally impossible for the accused to have committed the crime contemplated. Like I said, I think we can all agree it is impossible to commit murder on a dead man or a mannequin. (See for example, State v. Guffey, 262 S.W.2d 152 (Mo.)(1953). Which held that a hunter who shot a stuffed deer believing it to be alive had not attempted to take a deer out of season.)
Contrast that with cases of impossiblity in fact, though and we get a different result. This occurs where, if but for a mistake in the alleged’s beliefs of the facts as they exist, the alleged would have sucessfully committed a crime. (See for example, State v. Mitchell, 173 Mo. 633, 71 S.W. 172 (1902). Holding that it is attempted murder to shoot into the intended victim’s bed believing he is there asleep when in fact he is some place else.)
The difference is a little ticky-tacky, but seems clear none the less. It is possible to kill a man who is still alive. It is not possible to kill a man who is already dead, or to kill a mannequin.
Having now gone through all of this, I must note that the Model Penal Code abolishes the impossibility defense. So, while under the common law it seems to me that you could have beat the attempted murder charge under a theory of legal impossibility, that defense, as noted by Jodi’s reference to her state statute, is no longer available to you.
I bow to Jodi and sailor as they clearly nailed this one. I will commence the eating of the humble pie.
