The recent buzz about gun laws is about to grow after the fourth mass shooting this month that occurred Monday morning, when a gunman shot at least four firefighters who were responding to a house fire in Webster, New York.

The gunman opened fire on the first fire crew that arrived on the scene.  Two of the firefighters were killed, and two were injured and are currently being treated at Strong Memorial Hospital.

After the initial shooting around 6 a.m., the firemen were told to retreat from the blaze by a SWAT team while they searched for the shooter, as the unknown gunman was still on the loose.  As of 10 a.m., the gunman was still not found.  The blaze had spread to three houses and a car, and the fire department moved back in to extinguish the blaze and prevent further damage.

Officials say there is no active shooter on the scene, but they are currently following leads that there may have been more than one gunman.

The shooting in Webster comes just weeks after the Sandy Hook Elementary School shooting that claimed the lives of 20 children and 6 faculty members.  It also follows a shooting at a Portland mall that claimed the lives of two shoppers, as well as a shooting at an Alabama hospital when a gunman and shot a police officer and two employees.
