Webster Police Chief Gerald Pickering said Tuesday that the man's sister hasn't been found yet. He said 62-year-old ex-convict William Spengler armed himself with three weapons and set his house afire to lure first responders into a death trap.
Two firefighters were shot dead and two others are hospitalized. Spengler killed himself as seven houses burned around him Monday.
