Sounds like possible symptoms of Depression, which the police are looking into as a possible indication of suicide. I saw a photograph of him that was shown on Fox News. He LOOKED depressed in the photo. That is not a diagnosis, btw, just something I noticed. If anyone can find and post the photo, it might prove interesting. Then there's the part about his brother committing suicide nine years ago, very near this time of year. Could Depression run in the family? Could he be depressed in part because of his brother's suicide? I have a sense this might be a personal, rather than a professional thing, but who knows? It might even be some of both. The "met with foulplay angle" is being played down by just about everyone, is it not? An impression I have, anyway...
