BISMARCK, N.D. (AP) — The FBI has confirmed that a body has been found in the truck connected to the disappearance of a New Town woman missing since last fall from the Fort Berthold Reservation.

FBI spokesman Michael Kulstad says the vehicle was recovered in Lake Sakakawea on the reservation and that a "victim" was found inside. He declined to say whether the body is male or female. Kulstad says the FBI is working on a positive identification, notifying next of kin and determining the circumstances of what happened.

Thirty-two-year-old Olivia Lone Bear was last seen leaving a New Town restaurant Oct. 24. Searches by authorities and volunteers for the mother of five had yielded no clues.
