Quote:An ex-con gunned down two firefighters after luring them to his neighborhood by setting a car and a house ablaze early Monday, then took shots at police and committed suicide while several homes burned.

Authorities used an armored vehicle to help residents flee dozens of homes on the shore of Lake Ontario a day before Christmas. Police restricted access to the neighborhood, and officials said it was not clear whether there were other bodies in the seven houses left to burn.

The sister of the gunman, who lived with him, was unaccounted for. The gunman's motive was unknown.

The gunman fired at the four firefighters when they arrived shortly after 5:30 a.m. at the blaze in Webster, a suburb of Rochester, town Police Chief Gerald Pickering said. The first police officer who arrived chased the suspect and exchanged gunfire.
