(Reuters) - Human remains discovered in North Dakota are believed to be those of a Montana school teacher who vanished while jogging near her home in January, the FBI said on Wednesday.
"While positive identification has not been made at this time, it is believed the remains are those of Sherry Arnold of Sidney, Montana," the FBI said in a written release, adding that further identification efforts were underway.
Two men from the western Colorado town of Parachute, Lester Vann Waters, 47, and Michael Keith Spell, 22, were arrested last month and charged with aggravated kidnapping in connection with Arnold's disappearance
Prosecutors say Spell has told them that Waters, in a crack cocaine-induced frenzy, ordered him to grab Arnold.
Spell told authorities that Waters then got into the back seat with Arnold, 43, and choked her to death, according to prosecutors.
