Wonder if calgary123 can shed some light on Brad's personality as it relates to the personality type associated with a catathymic homicide.
I don't really have much to add to say I know or don't know that. My posts in 2008 about his personality explain it in much better detail. And I'm only one observer commenting on something subjective. He was a brooder, someone who would internalize issues and you would only discover something was going on after the fact.
He was definitely sneaky, and would do things behind your back. The best example is breaking into his x-gf's apartment to snoop on her, but I know of other less dramatic examples.
Once we heard he was accused of murder, not one person said that Brad would never do something like that, and some of those people really liked him. That is odd in itself. There was something about his personality that was just unknown. This does not make him a murderer however. (Lieing about where Nancy went sure goes a long way to proving it though, and I think it has been proven, personal opinion only.)
One example, when Brad and I were moving in together, I was dating a girl who graduated with him from high school(must be same grad class as the newer poster here who went to school with him). When my girlfriend found out I was moving in with him (I didn't check with her first, I saw no reason to) she was very unhappy with me. I don't recall all the specifics but she thought he was "creepy" and "weird" and not to be trusted. I brushed this off as my girlfriend always had very strong, and often over the top opinions. I also had a good initial opinion of Brad having just met him, he seemed like a really nice guy and someone I would get along with. We had similar interests, in athletics, and computers, and cars. I thought she just wanted me to live alone so she could spend more time with me. At the time I had student loans and needed to keep expenses to a minimum. But sure enough, she generally would not come over if she knew he would be there. In that regard the new poster's comments kind of surprised me, saying his was nice and happy go lucky, having known him that long. I believe she is being genuine, so this shows Brad has many layers to his personality.
I was surprised to hear he yelled at Nancy. Its just not his way. Obviously things were really confrontational in their relationship and my guess would be Nancy instigated the yelling. I don't know if that speaks to a tendency toward catathymic crisis.
I also find it interesting that Nancy is completely out there with their relationship to anyone who asks (or even doesn't ask, Nancy just volunteers). This is so polar opposite to Brad I find it quite striking. Brad never talked about any of his relationships with anyone (even the "childhood friend"). He was just very private. I imagine this bothered Brad greatly, and I can't say I blame him, she was a little too open.
I spoke with one of the two people Brad identified as a "childhood friend" in the deposition, earlier today. That person thinks the nail is in the coffin and Brad will spend his life in prison. This also proves nothing, but I find it interesting.
All of this is just for general conversation and of course is not at all indicative of Brad's innocence or guilt as far as the law is concerned, I'm just putting some info out there.
