KLAMATH FALLS, Ore. -- The Klamath Falls Police Department is looking for a man they believe had something to do with the death of a 69-year-old Klamath Falls woman. 

Police are looking for James Marshall Johnson, 39. The photo police provided of Johnson is from 2007. 

Police responded to a house fire at 112 Wendling Street on Friday. They were told an elderly woman lived there. Officers found Joan Pittennger, 69, outside near a detached garage. Police say the woman had been severally beaten and had a weak pulse. 

Pittennger was taken to Sky Lake Medical Center. She had to be airlifted to a different hospital because her injuries were so severe. Klamath Falls Police say she later died at the hospital. 

During the investigation, police say they learned the fire was intentionally set. 

Johnson is wanted on multiple charges including murder, arson, assault, and menacing. Anyone with information is asked to call the Klamath Falls Police Department at 541-883-5336, or call the anonymous tip line at 541-883-5334.
