No they just found Junes and an unknown males DNA. had they not been contact wounds then the twins DNA would never get inside.
"According to Bob Woffinden, a second firearms expert testified that the .22 Anschütz was unlikely to produce backspatter, especially when fitted with a silencer" If Vanezis autopsy is correct and Twins did get contact wounds I am 100% sure its because you will not get drawback from that part of the body specially from a .22 it would have to be from fleshy places with allot of blood flow. Places like the neck, wrists or the chest if the bullet misses the rib bones.
1) June, Sheila and one or both of the twin's DNA was found in the moderator. Each of the ten tests featured a minor contributor who could have been the same person or all of them could have been different people. Someone for the defense felt that in 2 samples the minor contributor was male. Normally it is not possible to tell the gender from a sample so incomplete it is unclear whether that assessment was well supported or not.
2) Vanezis didn't assess that the twins suffered contact wounds
3) Woffinden was wrong about there being a second firearms expert who testified at the trial for the crown that is why he could not name the alleged witness.
4) Location is key in whether backspatter is likely to occur from a 22LR bullet or any bullet for that matter. Just because it is not likely to occur in a particular location doesn't mean it can't and won't. You find out whether it did or didn't by looking at whether blood is found in the weapon.
The location of Sheila's fatal wound was assessed to be virtually certain to result in drawback because her neck was full of blood- her initial wound caused internal hemorrhaging in her neck. The nature of her skin and blood in that location meant it would occur so long as it was a contact wound if not a contact wound then ordinary backspatter would have resulted. It would not have gone inside the weapon if not a contact wound. The defense could not find anyone who disagreed with this assessment and to this day hasn't found anyone who disagrees with it. That means the only hope the defense has of refuting that the blood in the moderator was drawback from Sheila would be to find evidence that she didn't suffer a contact wound.
Despite the fact that 22LR shots to the head don't usually result in backspatter and contact shots to the head don't usually result in drawback it can and does happen SOMETIMES. Someone here brought up a case in New Zealand where a 22LR contact shot to the head with a moderator ended up resulting in drawback in the moderator.
The defense thus has a quandary. That quandary is that even with a moderator attached the fatal wound is virtually certain to result in drawback. The defense wants to maintain the moderator wasn't used which means the odds of drawback would be even greater. Drawback would be certain if the weapon didn't have the moderator attached. Yet no blood was in the muzzle of the rifle.
So this goes back to what I stated earlier the only hope the defense has would be to find a way to refute that Sheila's fatal wound was a contact wound. If they could find a way to establish neither of her wounds were contact wounds that would negate that her blood could have gotten inside as a result of drawback and would help support either it was blood of other victims not her or was planted. Obviously by now the defense would have found an expert to refute the fatal wound was a contact wound if there were evidence to contradict Vanezis' assessment. The defense trial experts would have refuted such if any evidence had been available to use to argue against it.
Because the defense was unable to attack the evidence on such obvious grounds is why they have resorted to desperate stuff on appeal. This is why I laugh when people say just wait till the next submission. They used their best arguments already, whatever crap they come up with in the future if they can actually manage to put a submission together will simply be even weaker than the last. If a former cop actually came forward with allegation like mike asserts that could rock the boat but there is no such person it is just fantasy.
