STURGEON LAKE (AP) - Pine County authorities say they've arrested a 38-year-old woman for shooting a man after he told authorities his four gunshot wounds were self-inflicted.

The Sheriff's Office said Wednesday that authorities responded to a reported shooting Tuesday. Deputies found a man who said he had accidentally shot himself. He was taken to a Duluth hospital.

Investigators say evidence suggests the wounds weren't self-inflicted. Sheriff Robin Cole says people can't usually shoot themselves more than once.

Authorities arrested a woman believed to be the man's girlfriend on probable cause of first-degree assault. She's in custody at the Pine County jail. They expect to file charges Thursday.

The man was in serious but stable condition Wednesday.

Cole says investigators continue to conduct interviews.
