For you maybe this case is only balancing on DNA evidence. For me there are numerous witnesses included.
The juries in Italy also have to be at a certain education level to sit on a jury. It's funny that in Ryan's case you are ok with a jury convicting on so little. Yet can't see how an jury in Italy could convict AK and RS. There is a list of circumstantial evidence that is backed by witness testimony.
Ryan's case had the alleged co murderer taking a 25 year plea deal with the added bonus of an eyewitness. He described the murder in detail, implicated himself and painted a picture for the jury to believe or disbelieve. I myself would not have convicted on so little but I could see how a jury could convict. They believed the credibility of the eyewitnesses. There was also some motive
Here, outside of the DNA, I don't see what evidence can be used to support a conviction. What witnesses? Rudy?the heroin addict? What evidence supports the conviction once you take away the DNA and the false statement to police?
