NEW TOWN, N.D. -- The brother of a missing New Town woman on the Fort Berthold Indian Reservation in western North Dakota has confirmed that the truck she was last seen driving was found Tuesday, July 31, possibly in nearby Lake Sakakawea.

Matthew Lone Bear said he couldn’t answer a lot of questions, but said the truck was found Tuesday night. He said he couldn’t say where or how the truck was found, if it was on the Fort Berthold Reservation or how the vehicle was identified.

He also declined to say what was found inside the truck.

"We're still dealing with it," Matthew Lone Bear said.


The woman, Olivia Lone Bear, 32, has been the subject of massive manhunts since last fall with people from all over the state joining in the search.

It’s possible that the truck was found in the nearby lake as Tribal Chairman Mark Fox said Tuesday night that "purportedly" the truck had been found in Lake Sakakawea, but added there was "no formal verification from law enforcement yet."

"Until verification of all relevant data, I (have nothing) more to formally share," Fox said in an email.

Three Affiliated Tribes Police Capt. Grace Her Many Horses directed calls to  Mandan, Hidatsa and Arikara Nation spokesman Tony Lone Fight, who confirmed the truck was found, but could not offer other immediate details.

Lone Fight referred questions to the Federal Bureau of Investigation, which he said has taken over the investigation.

Olivia Lone Bear, 32, was last seen between 5 and 7 p.m. Oct. 25, 2017, in downtown New Town, driving a teal 2011 Chevrolet Silverado 2500 with North Dakota license plate 839 BRC.

The Bureau of Indian Affairs took the lead on the investigation in early February, amid search efforts from volunteers, the Lone Bear family and Three Affiliated Tribes Police.
