EXELEND, Wis. — The Sawyer County Sheriff's Office is asking for the public's help in identifying a serial arsonist, after they suspect the person set six fires in the span of ten days.

The first fires went up in the early morning of November 18 – two homes, one in the town of Meteor and another in the town of Radisson, are considered total losses. No one was inside either home at the time.

That morning, a third fire damaged the American Legion in Birchwood.

Days later, also in the early morning, a 911 call reported a fire at a Radisson gas station. The building took extensive damage.

Since then, another two fires have damaged buildings in the county.

In a release sent Wednesday, Sawyer County Sheriff Doug Mrotek released surveillance footage – in hopes someone would recognize a suspect they think is tied to the arsons.

"We urge anyone with information, no matter how insignificant it may seem, to come forward," wrote Mrotek in a release.

The Sawyer County Sheriff's Office is working with the Wisconsin Department of Justice on the investigation.
