Very interesting. Didn't know most of this although we'd touched on this before.Ok. This didn't occur to me until now, although I've mentioned it in past cases.
Genetic genealogy works by uploading offender DNA to a public genealogy website, like the most popular one, GED Match. That particular database includes DNA that people have uploaded from other services, which law enforcement cannot access (AncestryDNA for example).
From there, partial matches may be found which can then be used to develop a family tree, leading to the offender.
CODIS on the other hand, typically works on complete matches. That system is looking for the exact offender DNA, as opposed to a relative.
In most states, it is illegal for law enforcement to search CODIS for partial matches. Several states however, have no such restrictions.
Colorado is one of them.
Why searching a database like CODIS can be so helpful, is because crime tends to run in families. The offender may not be in there, but his father or brother might.
So our friend in Arizona did not leave that DNA, but someone related to him in some way did.
I imagine it's going to be time consuming and expensive to find someone who is ultimately irrelevant, but I guess it may be worthwhile in case the jury isn't capable of thinking on an average level.
Find him, and you shut another door to the defense, and it's "Gone Girl" again.
I agree it would be very worthwhile for the prosecution to utilize their services. It would be, imo, more than worth the expense as opposed to the defense drawing out exuberantly lengthy court costs. And, you know they will. It's all they have to TRY to convince a jury that there's reasonable doubt.
The prosecution need to cut that off at the quick.
