A woman killed in her home over the weekend on the Fond du Lac Indian Reservation west of Duluth has been identified, and her husband and a younger woman are in jail awaiting charges, authorities said Wednesday.

Waubunoquay D. Randall, 31, was stabbed Sunday in Stoney Brook Township, according to the medical examiner's office.

Her 31-year-old husband, who lives in nearby Cloquet, was arrested Monday and remains jailed on suspicion of second-degree murder. Also jailed as a suspect in the killing is a 21-year-old woman from Stoney Brook Township.

Authorities have yet to explain what role each may have played in the killing. Charges against one or both suspects should come by noon Thursday, the county attorney's office said.

Sheriff's Lt. Jason Lukovsky said Randall suffered "multiple stab wounds" with a knife, and "we believe we do have the murder weapon."

About the time investigators were in Randall's home Sunday, a suspicious fire was burning in a home down the street, the lieutenant said. Clothes were found on fire in an oven, and that incident "could be related" to Randall's killing, Lukovsky said.

The clothing has been recovered for examination by state forensic experts, the lieutenant added.
