Japan anime studio fire: Man shouting ‘You die’ bursts in and sets blaze that kills 33

Don't know if I should have put this under anime, but I think its good here.

"She told NHK public television that the man had burns on his arms and legs and was angrily complaining that something of his had been "stolen," possibly by the company."

I think he may have wrote his own manga and shared it with someone who works for the company that company stole is story and present it to the company as his own trying to make a deal and a deal has been reach and he was upset about being kept out of it.
