I hope he gets at least 10 years for his efforts. Madoff bilked his clients of $18b and got 150 years.
It is possible for him to face life in prison. According to the Criminal Complaint published by the NCIS, he did all this for some ex-girlfriend he was texting. He starting developing some un-controllable anxiety while standing the safety watch and didnt like her responses. Apparently she started seeing some other guy, and he was trying to convince her that he was more than a friend. He wanted to get out of work. Since he was a unionized tradesman he wanted to still get paid, so I guess one way to do it, is if there was no actual work in the yard. With his twisted logic, a fire would accoplish this. He actually did it twice. He might of got away with the USS MIAMI fire if he didn’t start the second one.
