Blood Expert Pokes Holes in Chris Vaughn's Killing Story

Another expert witness told the jury how he found some serious flaws in the story Christopher Vaughn told the police about how his wife and three children ended up dead.

Alleged quadruple-killer Christopher Vaughn's story about how his wife gunned down their three children before taking her own life was disputed by yet another expert witness Tuesday.

Bloodstain pattern expert witness Paul Kish said Vaughn's wife, Kimberly Vaughn, 34, must have been killed before Vaughn bled on her.

Kish was so adamant in his assessment of the blood evidence that he prompted defense attorney George Lenard to demand a mistrial.

Kish said the blood evidence and the "facts of the case" showed that Christopher Vaughn, 37, was shot and wounded after someone stuck a gun under his wife's chin and pulled the trigger.

"I think he already testified to the ultimate issue in the case," Lenard protested. "He also said the facts of this case dictate that Kimberly Vaughn was shot before Christopher, and that's very problematic."

Will County Assistant State's Attorney Michael Fitzgerald countered that he "didn't think (Kish) was trying to opine on the ultimate issue in this case," but Lenard didn't believe any of that.

"He has" opined, Lenard said. "The state's wrong and I'm going to make a motion for a mistrial."

Judge Daniel Rozak called a recess so he could research some points of law, then denied Lenard's mistrial motion.

Christopher Vaughn had told detectives he fled to safety after his wife shot him in the left thigh and left wrist while he was sitting in the driver's seat of their parked Ford Expedition in June 2007. Kimberly Vaughn, who was sitting in the passenger seat, then turned around and put bullets in the head and torsos of each of her three children—Blake, 8, Cassandra, 11, and Abigayle, 12—according to Christopher Vaughn's account of the killings.

Vaughn's defense is his wife's murderous rampage was fueled by the antidepressants and migraine headache medication she had been taking. He also told investigators that he had recently confessed to his wife about a sexual affair he carried on during a trip to Mexico, and that this upset her.

Kish was the second expert witness in as many days to point out the gaps in Christopher Vaughn's account of the shootings. On Monday, ballistics expert Matthew Noedel said

vaughn's bullet wounds were on the wrong side of his body and that they were inflicted by a gun barrel held flush against his skin.

Also, a pair of shell casings found on the driver's seat of the Expedition likely ended up there after Vaughn got out of the car, he said. And the Taurus semi-automatic pistol, which all the bullets were fired from, cycled completely through after the last round was discharged. Noedel said that indicated the final shot probably wasn't put in Kimberly Vaughn's head by her own hand.

Fitzgerald said prosecutors still have two more witnesses to call. They have already brought in 86 witnesses to testify over 16 days.

Which part is "hearsay"?

That's what Francis would say.

When you call an expert witness you need to give some credence to his testimony. Mistrial? Hardly.

Do we even know why he pulled off onto the frontage road in the first place??

Hi, ChannMom -- His story is his wife was feeling ill and he was seeking a private spot in case she needed to get sick. His defense attorney says that was pretense so that she could shoot him, his family and herself. The prosecution says he likely told his wife something else to justify them leaving the interstate -- maybe that he needed to check their rooftop carrier, which he said he did.

Because there would have been so many potential onlookers at 5 am on the unmarked exit, it was necessary to go onto the gravel road....hilarious.
