According to Cacamerba, his blogging name was Jaya Negara and his blog can be found at http://jayanegara1234.blogspot.com/
Here's a snap shot picture of his profile..
Apparently he was also a fan of 'Insan Insan Pendakwah', Abatasa, Mistifiles and several other blogs who frequently discussed paranormal things and the prophecy of the end of time.
In MYKMU several authors has published their opinion that he is PAS supporter but upon brief perusal of his blog I believe he is neither PAS or UMNO supporter. He admire Mahathir, yes - but he despised the Sultans.
I guess one can say he is a troubled man. He wrote 17 lengthy articles in just a month! And the way he wrote tell me how troubled his mind was.
I've seen the youtube video of the shooting and I was quite disturbed to hear someone yelling 'TEMBAK' and `BUNUH' repeatedly after three shots has already been fired. I hope the government will investigate the identity of the person who yelled this before the opposition take it as an opportunity to smear the police credibility.
Whatever it was, lets hope he ends well in the afterlife.
