Early life and crimes
William Leslie Arnold, known as "Les," was born on August 28, 1942. His father, Bill Arnold, owned the Omaha region office of Watkins Products, a direct-sales company, while his mother, Opal, was a homemaker. Neighbors described him as "high strung" and stated he had a temper, but also that he was intelligent and talented. He was in the ROTC and was a B-average student.

In 1958, at the age of 16, he murdered his parents and buried them in the backyard of the family home in Nebraska. This came after a fight with his mother over usage of the family car to drive to a date. He hid their bodies in the basement and took his younger brother, who did not know about the murders, to a neighbor's house before digging a trench and burying their bodies. He then took his girlfriend to the movies with the car. After the killings, Arnold lived at the house, still attending school and telling others his parents had merely gone on a sudden trip.

After leading the police to his parents bodies, on October 11, he pled guilty, was sentenced to life in prison in 1959, and was sent to the Nebraska State Penitentiary. He was described as a "model prisoner" who could have qualified for early release.

Escape
On July 14, 1967, Arnold and another inmate, James Harding, escaped from prison, cutting through the bars in a prison music room and climbing a 12-foot barbed wire-topped fence. Harding was recaptured the next year, but Arnold could not be located. He was the last inmate to successfully escape from the Nebraska State Penitentiary. The fellow escapee told investigators he and Arnold had gone to Chicago but split up from there. The case was investigated by the FBI into the 1990s, and then turned over to the Nebraska Department of Correctional Services before being turned over to the U.S. Marshals in 2020.

He moved to California, then to Florida, and eventually to New Zealand in 1978. In 2010, he died in Tamborine Mountain, Australia, due to complications from blood clots. He had been living under the alias John Vincent Damon. During his lifetime, he married twice and fathered two children. He told his children he was an orphan.

Discovery
Knowing only that his father was an orphan, Arnold's son, who had been only 19 when he died, decided to learn more about him. He visited Chicago in 2018 and was told that his father's birth certificate was falsified. In 2022, he decided to take a DNA test from Ancestry.com, and was contacted by the Marshals.
