The Brooklyn man who lit a fire that killed five neighbors told cops that demons in his head drove him to do it. Daniel Ignacio, a Guatemalan national, was charged on Tuesday with murder and arson for the fire on Sunday in Bensonhurst. Ignacio, who was drunk at the time, said “the demons made me do it” and said he does “stupid things” when he drinks. He lit the fire with paint thinner and a roll of toilet paper. When he awoke from his stupor and realized what he had done, he helped a woman rescue her two children. The woman died in the blaze. Ignacio told cops he was depressed in recent weeks about making $8 an hour as a day laborer and being so far from his family.
