This article gives a little history on the case. Some things don't add up. There's some articles from a few years ago that describe how his psycho ex wife tried to frame him and get him court martialed for child rape. He was subsequently found not guilty/ acquitted. But he did get court martialed for mishandling classified data. As for the murders, that's gonna be a huge case! No doubt the ID Channel will one day run a special episode on this!
