One of the residents of a Milwaukee apartment building wonders if a neighbor has enemies after three fires in three nights. No one was injured when the third fire forced residents out of their beds before the sun was up Thursday. Firefighters say it’s not normal to be called to the same address so many times in such a short period of time. All three fires were started in common areas, but they haven’t officially been labeled arson yet. Residents say they are worried about a fourth fire.
