Christopher Vaughn is an American man convicted of the murder of his wife, Kimberly, and the couple's three children in June 14, 2007.
[2] Christopher Vaughn, his wife Kimberly, and their three children moved to Illinois from the Seattle area approximately two years prior to the fatal shooting.
Christopher had started a licensed private detective agency in Washington called Stone Bridge Security that specialized in cybercrime.
The Vaughns decided to close the business when Christopher was offered a job at Navigant Consulting's computer forensics group, and the family moved to Oswego, IL in 2005.
[3][4] In the early morning hours of June 14, 2007, the family left their home in Oswego to drive to a waterpark in Springfield, IL.
She gets mad when I don’t call her.” Christopher was brought to the police station after being treated at the hospital and was interviewed for nearly 14 hours on June 14.
He remembered pulling off, parking in front of a cell phone tower along a frontage road, and getting out of the car to check the back tires.
He told police he had re-secured the strap on the topper, got back into the vehicle, and noticed that his leg was bleeding, but he claimed to have no memory of him or his family members being shot.
During his trial, a forensic pathologist testified that Kimberly Vaughn was taking two medications known to cause increased risk of suicidal thoughts and side effects including confusion or agitation.
Robert Deel, a Crime Scene Investigator who worked on the case has openly supported Vaughn, claiming that the bullet trajectory and other forensic evidence points to Kimberly as the shooter.
"In fact, every time that I offered up something that was contrary to what they said, they had some reason why I didn't know what I was talking about, and basically it all fell back on that Christopher Vaughn is a criminal mastermind and he knows all about crime scenes and that he would be able to fool me into thinking that something else happened."
A year after her death, the FDA released a report stating that a statistically significant risk of suicide was seen in patients taking Topamax, as does Nortryptiline.
In an email written two weeks before her death, she told Christopher that she informed her doctor she was experiencing “a big personality change and anxiety change.” Kimberly's level of Nortryptiline was found to be in the low end of the toxic range.
