Two people are dead and several others where injured after a gunman opened fire on first responders attending to a house fire.

The incident was reported in Tucson Arizona.

Authorities say they responded to a house fire around 3:45 p.m. when a neighbor opened fire on them and civilians.

A  20-year-old ambulance driver was shot in the head while a 21-year-old paramedic seated in the passenger seat, was shot in the chest and arm.

The shooter then went on to shoot a neighbor in the head and a firefighter in arm before shooting at another neighbor.

The neighbor who was shot in the head was pronounced dead at the scene, while the firefighter, the ambulance driver, and the paramedic were taken to the hospital for treatment for their injuries.

A police officer was able to track down the gunman a few blocks away from the scene and rammed the suspect’s vehicle with his vehicle.

The suspect reportedly then opened fire on the police officer and was killed when the officer returned fire.

Once fire fighters put out the flames, they located a “badly burned” body inside the home.

Several children who were said to live in the home where initially reported missing, however, they have since been located unharmed.

Officials are still unsure what prompted the attack but are reporting that they are still investigating.

“We are continuing the investigation and not releasing anything additional right now,” Sgt. Richard Richard Gradillas said.
