Marilyn Jean Arbaugh was born on 9 September 1947 in Wendell, Idaho, the daughter of James and Mary Bell. By the early 1980s she was a single mother of two teenage daughters, Tiffany and Tyra, and worked as a waitress at the Butte Cafe in Jerome, where she also kept horses on a rented ranch outside town. She had been married to John Adamson for about six years and divorced him in 1981.
The relationship was violent from the start.
The marriage ended in divorce on 13 June 1984. At two o'clock the next morning two women from Lewiston stopped near Wendell and Marilyn jumped out of a Fiat station wagon, screaming for help with red marks on her neck. Her car was later found high-centred and burned on a rough road, with the visible VIN numbers scratched out.
A warrant for kidnapping and rape was issued on 25 June 1984. He told a cowboy named Gary from Elko that he was a rodeo clown from Arizona who was counting studs for the government, and at the Simplot Livestock camp he introduced himself as Sam from Montana, saying his horse had run off and his truck had run out of gas. On 28 June, while still wanted, he walked into a hardware store in Gooding and bought a Remington .22 rifle and two boxes of ammunition, saying it was a graduation present for Tyra. Witnesses remembered him carrying a woman's purse backpack.
She spent the night there and came home to the ranch at L Rancho 93 on Highway 75 at about 10.30 on the morning of 1 July 1984. Her daughters were home: Tiffany, sixteen, was reading and Tyra, fourteen, was running a bath. At about eleven Marilyn went out to move some horses that had got into the wrong corral.
Shortly afterwards Tiffany heard gunshots. She took her mother's .22 Ruger from behind the radio in Marilyn's room and ran outside. He said he was going to take her to the doctor. Both adults told Tiffany to leave.
The girls hid behind a sheep wagon near the corral, calling for their mother and hearing nothing. Tiffany, shaking, accidentally fired the pistol; the bullet nearly hit the family dog and gravel sprayed the barn. They heard more shots, ran inside, and then went back to the barn. Tiffany found Marilyn on her back with her arms over her head, lifted her shirt and saw the wounds. Tyra brushed her mother's cheek and blood ran from her mouth and nose. Tiffany said her mother had been looking at her one moment and was gone the next, and she closed her eyes.
The Remington was lying nearby. Only fourteen bullets were missing from the ammunition he had bought, a discrepancy the defence would use for years.
He said she pointed the rifle at him, told him no other woman would have him, and that he grabbed the barrel, closed his eyes and the gun went off several times. He claimed Tiffany then came out with a pistol, said she hated them both, fired at him, and then stood over her mother and fired the fatal shot. He could never explain the fifteen wounds, the clustered chest wounds or the shots that entered her back.
He also let his client testify at the pretrial hearing. Bennett's former legal secretary later said that Bennett and his investigator had consulted a niece in California who conducted a seance with Marilyn, and that the investigator claimed to be in regular contact with her spirit. Bennett denied it.
Tiffany and Tyra testified. Tiffany described finding her mother and the accidental shot; the defence never asked her whether she had killed her mother, although that was its whole theory. Tyra described being pulled from the bath and hiding behind the sheep wagon. A deputy, Ernest Coates, testified that the prosecutor Dan Adamson had told him the spent casing from Tiffany's pistol was not important and could be discarded, and that he had thrown it away.
He imposed death.
In 2011 a 1989 letter supposedly written by Tyra to Judge Becker was discovered; it claimed that police and prosecutors had pressured her to give false evidence and that the girls had rifles of their own that day.
In May 2017 the Idaho Supreme Court reversed that decision. It found the successive petition procedurally barred, the letter riddled with contradictions, including a reference to a street dance that happened ten days after it was supposedly written, and the claims already rejected.
