U.S. Marshals confirmed that Logan McFarland and Angela Atwood were arrested Tuesday afternoon near the Big Springs Ranch by Elko County Sheriff's deputies.
U.S. Marshal spokesman Jim Phelps said that McFarland and Atwood were spotted by a rancher in a plane walking about 30 miles west of Wendover and a mile south of Interstate 80. The rancher contacted authorities and led them to the location where he saw them.
Phelps said McFarland and Atwood were spotted Saturday in a stolen vehicle and officers pursued them at speeds of over 100 mph.
Officers eventually lost contact with the car, but believe the vehicle broke down on a back country road where McFarland and Atwood abandoned it and continued on foot before being spotted by the plane. The vehicle had not yet been located as of late Tuesday afternoon.
McFarland and Atwood were named in an affidavit obtained by ABC 4 News as the persons who police say may have been responsible for the deaths of Dorothy Ann and Leroy Woody Fullwood, who were found covered in blood at their home in Mount Pleasant.
Police say the couple is also responsible for the kidnapping and shooting of another woman in West Wendover, Nevada.
The document suggests McFarland and Atwood "borrowed" a friend's car while attending a party in Moroni on December 29, but did not return it.
The affidavit said that a witness reported that McFarland returned to the Moroni residence at about 2:00 a.m. on the 30th and bragged about having obtained cash and firearms.
The witness told police that McFarland and Atwood left sometime during the night, and that when the car's owner asked him about the car, he texted McFarland, suggesting the car might be reported as stolen if he did not return it. According to the affidavit, McFarland called the witness and told him the car was parked near Santaquin.
Police say the witness burned some of the items, fearing they were stolen.
According to the affidavit, the witness later read about the Mt. Pleasant homicides and called police to report what had happened.
Meanwhile, police in Santaquin reported another stolen vehicle that turned up later in Wells, Nevada.
At about the same time, the affidavit said that a woman was kidnapped at gunpoint from a West Wendover casino by a woman later identified as Atwood. The woman was shot in the head as she escaped a short distance away from the casino, according to police.
West Wendover police also indicated that another vehicle was stolen from the area shortly after the alleged kidnapping and attempted homicide.
Police said McFarland and Atwood were both considered armed and dangerous.
According to police, McFarland and Atwood were last seen in Nevada driving a stolen gray Volkswagen Jetta with Colorado license plate 725WHX.
The woman who was kidnapped and shot was later identified as Rattana Lirange of West Wendover. She was reported to be recovering at a Salt Lake hospital.
Police also released surveillance photos of a man at a West Wendover truck stop believed to be McFarland. They also found a receipt for a Del Taco food order in the car stolen from Santaquin. The receipt indicated that the card of LeRoy Fullwood was used to make the purchase.
