America the Dead: Los Angeles. America the Dead, #2

Billy was up on the roof. Beth, Jamie, Winston and Scotty were standing at the edge of the building as he was, looking out over the city. Things were crazy, and they seemed to be getting worse as the days rolled by. The police precinct was still burning. It had started sometime during the night two days before, and since there was no one to put the fire out, it had been raging for hours now. A few minutes ago, the roof of the building next door to the precinct burst into flames.
Maybe the fire had started inside, or the extreme heat from the burning police precinct had caused it to burst into flame, spontaneous combustion, but it was a strange thing to watch. It appeared as though it had simply burst into flames all on its own. The animated conversation about whether it had been spontaneous combustion or a fire source from inside the other building that had simply burned through, had kept up for a few moments, and then they had all lapsed back into silence.
