Sorry, I don't care what medication he took, how old he was, what a "wonderful" child he was. He beat his parents to death with a hammer because he wanted to have a party. He signed autographs in jail saying "it's hammer time." Lock him up, throw away the key, and be thankful that our world will be a little safer.
Thanks Tigerbalm, I remember this case. I am confused though - he has been found guilty and this is penalty phase, right?
