Did we try the deceased suspect in court or just provide a summary judgment so the police could close the case and feel good about eventually "solving" the crime?

I used to prosecute gun cases and we routinely DNA tested the guns. I can't recall a single instance where there was only one person's DNA on the gun. It was always a mixture.


Couldn't you just arrest them all and charge them all?

A tangential issue. There are warehouses full of rape kits with evidence that hasn't been tested for DNA matches. That's tens of thousands of American women who, unlike the majority of rape victims, came forward and endured the collection of evidence from their bodies. But because of lack of funding -- or just plain prosecutorial priority -- their cases go unsolved.

19:00 answered your question. It’s unconstitutional. Your idea is a nonstarter.

Great use, however unconstitutional. Next

If my DNA is found at a crime scene, am I guilty?


Why was your skin or blood under the victim’s fingernails? Under what circumstances was that a commonplace occurrence for you both?

Because that’s not how DNA works

According to the US Constitution the government needs a warrant based on specific facts that implicate someone as a criminal before it is legal to execute a search. That’s why your idea is a non starter.
