TULSA, Okla. -- Shocking new evidence was introduced in the Michael Bever trial on Wednesday.
The Broken Arrow teen is accused of stabbing six family members, killing five. His brother, Robert, has already pleaded guilty.
The DNA analysts found clear genetic ties to their father on Robert, with the potential of DNA from the other five victims on his clothing as well.
Michael's clothes were tested also, showing multiple stains that matched his mother, April Bever. But DNA from the other family members were excluded.
"What this crime scene has been described as, you would expect someone involved with what they've accused Michael to be involved in to have everyone's blood and DNA on him. He did not. That's the significant part we were trying to bring out with that testimony," Chief Public Defender Corbin Brewster said.
On a seven inch knife there was significant DNA ties to Michael on the handle. The expert said the odds of that DNA belonging to someone else is less than one in a quadrillion.
The defense pointed out that when Robert's hands were tested, it showed evidence of Michael's blood. The analyst agreed with Brewster it is possible that Robert could have passed DNA from Michael onto the knife.
