Here is an article with the latest from the defense lawyer.

It is interesting because it shows what the defense may be when the case comes to trial. The lawyer says "There's no `CSI' information." and speaks of various things that call into question mental capacity. The killer is continuing with the story that there is no memory of the events except "the smell of gunfire and of human bodies but not much more."

Also another incident that involved violent behavior toward others has been reported. This one in 2008.
