There's something very odd here.
I'm with those who are very curious about Mr. Vaughn.
I poked and poked around trying to find out more about his firm, and for a
computer security firm, StoneBridge Investigations and Security had what seemed to be very low profiles. That makes no sense to me when your business is investigating things cyber-related. In WA, Vaughn did have other employees -- a guy named Mike Hendricks listed his job in a campaign contribution form as StoneBridge Security CEO, and his address was in Bellevue, WA. But otherwise, not much to learn about that company, at all, save that it looked legit 'on paper.'
And no matter what Mr. Vaughn says, the timing and just about everything else having to do with the idea that his wife did this make no sense whatsoever. Not to mention people living in the area near where the vehicle was found reported
hearing shots 3 hours before a 911 call was made.
Kimberly was raising impressive kids, according to the news stories I read. She had potted plants in front of the house. That photo of the family from the May 27, 2007 article in a paper about the home they bought in Oswego showed them in a bright, cluttered kitchen. I don't know about anyone else here, but I've known suicidal people. They didn't often tend their plants or keep cheery yellow kitchens. There are always exceptions.
I think the police are being very careful and cagey here. The outcome may be exactly what we all expect, though.
