A Redmond-area woman faces a first-degree arson charge after she allegedly set fire to a motorhome after a dispute Saturday afternoon, according to a Redmond Police news release.

After police responded to county property in the area of NE 17th Street and NE Hemlock Avenue just after 3 p.m., witnesses reported they had seen an argument between a man and a woman, identified as Janice Knieriem, 36, just before a fire starred, police said. Smoke from the fire was visible throughout Redmond.

Knieriem allegedly went into the motorhome after the man left on a bicycle and doused clothes with gasoline before setting them on fire, igniting a blaze that caused a total loss to the home, police said. Knieriem left the motorhome and was later found at a nearby travel trailer on Deschutes County property, police said. The man has not been found, police said.

No one was injured and no pets were inside the burned motorhome, police said.

Along with the arson charge, Knieriem had an outstanding arrest warrant from Crook County for an unrelated matter, police said.

Though the fire happened just outside the city limits, Redmond Police was named the lead agency in the investigation. Redmond officers were assisted by the Deschutes County Sheriff’s Office, Oregon State Police and a Redmond Fire marshall.
