Vaughn's Blood Found on His Wife's Clothes, Seat Belt, DNA Expert Testifies
Blood from both spouses found on Kimberly Vaughn's seat belt, which may have been unlatched after her death, could be a blow to the defense.
Drops of Christopher Vaughn's blood were found on his wife's shirt, shorts and the floorboard near her feet, a DNA specialist testified Friday.
And drops of Kimberly Vaughn's blood were found on her husband's jacket, Illinois State Police forensic scientist Kelly Krajnik said.
Taken alone or together, both seem to contradict Christopher Vaughn's story that his wife, perhaps angered by his alleged infidelity, shot him in the wrist and thigh as he sat in the driver's seat of their SUV and then -- after he fled the scene -- shot herself and their children.
Perhaps just as damaging to Vaughn's defense was evidence Krajnik presented about blood from both Christopher and Kimberly Vaughn being found on the seat belt and buckle on Kimberly Vaughn's side of the vehicle.
Given that she was not wearing a seat belt at the time police discovered her dead body, those blood stains would seem to indicate the Oswego woman had been wearing it at the time she was shot, that someone unlatched it after the fact and that a bleeding Vaughn was near his wife sometime before or after her death.
Previous testimony indicated that if Kimberly Vaughn was the shooter, she would have fired the gun about six inches away from his leg and less than an inch away from his wrist.
Christopher Vaughn told police he left the SUV to seek help and during the period he was gone, Kimberly Vaughn shot each of the children twice before turning the gun on herself.
However, prosecutors maintain Christopher Vaughn was the actual shooter and that his injuries were self-inflicted in an attempt to add credence to his story.
In testimony presented earlier in the trial, another Illinois State Police forensic scientist testified that she analyzed the bullet holes found in Christopher Vaughn's jacket and determined that one set would have been made by wrapping the 9mm gun in the jacket and then firing it.
A piece of flesh found found on the bullet hole was examined for DNA by Krajnik, who said it came from Christopher Vaughn.
That could support the theory that Vaughn wrapped the gun before shooting himself in order to cushion the blow.
Krajnik was asked to analyze DNA from blood spots found on the murder weapon, in the front area of the SUV, on clothing both spouses were wearing the day of the shooting and on items found in the car, including a paperback book and a water bottle.
What she determined, she said, was blood on both the driver's and passenger's seats and on the console between the two belonged to both Kimberly and Christopher Vaughn. Blood on the outside of the gun was from Kimberly Vaughn as were spots on the book and water bottle near the console, Krajnik said.
Three stain samples taken from Kimberly Vaughn's shirt were determined to be Christopher Vaughn's blood as were clusters of drops found on the left bottom area of Kimberly Vaughn's shorts, Krajnik said.
Testimony was also presented by Illinois State Police forensic biologist Katherine Sullivan, who said she tested additional blood samples found on both sides of Kimberly Vaughn's seat belt and determined they came from Christopher Vaughn. She also tested the blood spot found on Christopher Vaughn's jacket, near the front left pocket, and determined it belonged to Kimberly Vaughn.
The trial will enter its fourth week on Monday, with the prosecution expected to rest by mid-week.
