There is no argument about investigating him for murder or clearing him of murder because murder did not happen if he is the suspect.
I’m not so sure of that.
First off, here is the Colorado statute in question:
The responsibility of a person for his conduct is the same for persons between the ages of ten and eighteen as it…
colorado.public.law
Very short and sweet, Key phrase: “No child under ten years of age shall
be found guilty of any offense.” (emphasis mine)
Now take a minute to read about
affirmative defenses.
“An affirmative defense to a …criminal charge is a fact or set of facts other than those alleged by the plaintiff or prosecutor
which, if proven by the defendant, defeats or mitigates the legal consequences of the defendant's otherwise unlawful conduct.” (emphasis mine)
Now, take a look at
this list of affirmative defenses issued by the state of Colorado for a variety of crimes. See in particular pp 13-14 under “H:13 Insufficient Age - Under Ten”:
“In addition to proving all of the elements of the crime charged beyond a reasonable doubt,
the prosecution also has the burden to disprove the affirmative defense beyond a reasonable doubt.”
In this case, being under the age of 10 is the affirmative defense for any crime. Since it wouldn’t have been possible to prove beyond a reasonable doubt that BR was
over the age of 10 at the time the murder occurred, any legal consequences of that act would be defeated.
However, more to the question of investigating BR etc, - in my opinion, all of the above absolutely implies that under-10s can be suspects, investigated, and all the rest, and likely explains why BR also had his own attorney at the time.
Just because he couldn’t be prosecuted doesn’t mean he wasn’t investigated- whether he actually was or not is somewhat up for interpretation, but I think it’s likely there was some amount of it, at least - the 3 interviews alone seem to imply it.
Anyway, I’m not a lawyer, but my take here, based on the above reading, boils down to: “there wouldn’t be a need for an affirmative defense for under 10s if they couldn’t be investigated/arrested/etc for committing a crime.”
