So I'm wondering if they did some sort of pre-testing the clothing for blood.
If they didn't find any, they likely would not have sent them on to be tested by the lab?
His muddy and bloody coat should have had some kind of remaining stains on it if he did the murders. Shouldn't it?
He obviously had no tan coat or they would have taken it, too. No tan sweatshirt, either.
There should have been something worthy of exam in his brown cap but nothing is noted on the return.
For me, this all backs up the D claim that there was nothing linking him to the crime scene, according to LE.
Do we have any science about years old bloody clothing?
