A horrified court room looked on today as a man who had just been convicted of burning down his $3.5 million mansion collapsed and died in front of them. Michael Marin, 53, was found guilty of arson by a jury in Maricopa County Superior Court. He appeared shocked and closed his eyes as the verdict was read before appearing to put something in his mouth and wash it down with liquid in a plastic water bottle. In the shocking court room video, he then fell to the floor a few minutes later in convulsions. Mr Marin was taken to a hospital in Phoenix, Arizona, where he was pronounced dead.
