BEMIDJI, Minn. (AP) — Police say two Bemidji men have been arrested for their roles in the disappearance of a Redby woman, and investigators are working to identify a body found in a shallow grave.

Bemidji Police Chief Mike Mastin on Thursday announced the arrests this week of the 40-year-old and 31-year-old on suspicion of second-degree murder.

He says a third man remains a person of interest in the disappearance of Rose Downwind. The 32-year-old was last seen leaving a Bemidji residence Oct. 21 and was the subject of extensive searches.

Mastin says investigators are waiting for the Ramsey County medical examiner's office to complete an autopsy and confirm the identity of a body exhumed from a "shallow clandestine grave" northwest of Bemidji.

Downwind is the granddaughter of American Indian Movement co-founder Dennis Banks.
