David Lee Stensrud, 56, of Detroit Lakes was charged with second-degree murder Friday in the Wednesday incident, The (Fargo, N.D.) Forum reported.
County Attorney Michael Fritz said a woman called 911 Wednesday and said Stensrud had shot and killed 69-year-old Geraldine Kading and was going to kill himself.
When police arrived at the scene, Kading was dead with an arrow in her chest and Stensrud was alive, lying on a bathroom floor, Fitz said. An arrow was protruding from his chest and a crossbow was on the floor next to him.
Stensrud was transported to a hospital. His condition was not reported.
