The Minnesota Bureau of Criminal Apprehension is investigating an incident where multiple deputies shot and killed an arson suspect who allegedly shot at a firefighter in Normanna Township, Minnesota, on Tuesday.

The St. Louis County Sheriff's Office says its 911 center received a call reporting a structure fire on Heritage Trail near East Pioneer Road in the northeastern Minnesota town around 9:20 a.m. The caller reported their neighbor had sprayed a family member with gasoline and set their home on fire, as well as his own.

A short time later, another neighbor called 911, saying the same man was armed with a rifle.

The man, identified by the Minnesota Bureau of Criminal Apprehension as Adam Clinton Wolf, 57, allegedly tried to set a fire to another nearby residence, but a solo volunteer firefighter arrived and was able to help put out both fires at the neighboring homes.

As the firefighter left one of the houses, he reported hearing shots fired and began to shelter in place. A Duluth Township police officer arrived on the scene soon after and also reported being shot at, according to the sheriff's office.

Just before 10 a.m., five St. Louis County deputies approached the area. The BCA says Wolf shot at them, which led to all five deputies discharging their weapons, hitting the suspect.

Despite life-saving measures, Wolf died at the scene. No other injuries were reported to first responders or neighbors. 

According to the BCA, a firearm "similar to a shotgun," shell casings and "improvised shotgun-type devices" were found at the scene.

The BCA says the deputies involved in the shooting are Sergeant Zachary Peterson, Deputy Charles Bennett, Deputy Matt Miranda, Deputy Forest Lunemann and Deputy Michael Pikul. They have all been placed on administrative leave, per standard operating procedures.

All five were wearing body cameras, the sheriff's office said. The BCA says it will review the footage as part of the investigation.

Normanna Township is located about 18 miles northeast of Duluth.
