According to the WMUR tv report, the police said that he told them that he set the fires because he was bored. How about that...he set the fires because he was bored...I suppose that is a believable reason but thinking a little deeper into that reasoning....it does not speak well for the individual's character or self-control.
A fire makes an incredible destructive mess.
If he was bored, he should have simply taken up ice fish'n and beer drink'n like many do to pass winter boredom.....and maybe build a campfire out on the lake ice.... or stay home and argue with the wife.
