D an G used to work as a police officer, though he's probably best remembered for his crimes than his service. He was a believer in Nostradamus's prediction that the world would end in the year 2000, and when the new millennium rolled around, he acted on that conviction—shooting multiple people in what amounted to a violent panic. He didn't stay free long after the dust settled. He was arrested and sentenced to 20 years in Green Dolphin Prison.
