92-year-old Idaho man allegedly traveled to Utah to kill family members over inheritance dispute

LAYTON, Utah (ABC4) — A 92-year-old Idaho man was arrested in Utah after traveling across state lines with a plan to kill his nephew and his nephew’s wife.

Billy J Nevills, 92, has been arrested on two counts of attempted murder. He has not been formally charged yet.

According to the arrest statement, on Sept. 28, 2025, Nevills traveled from his residence in Twin Falls, ID, to Utah. He would allegedly later tell investigators that he was driving around and looking for his nephew’s house with the intention of killing him.

The Layton City Police Department located Nevills in Layton on the morning of Sept. 29, and he was taken into custody. It’s currently unclear how he was located. ABC4.com has reached out to police for more information regarding the arrest, but has yet to hear back.

During an interview with the police, the 92-year-old explained that he wanted to murder the two over a family trust and will issue. Nevills stated that when his wife’s sister passed away, his wife was supposed to inherit her sister’s estate. However, Nevills’ nephew was able to get the will changed and “ultimately placed the entirety of the sister’s inheritance” in the nephew’s name.

Due to this change, Nevills said that he and his wife lost all of their claim to the inheritance.

According to Nevills, his wife is currently living in a care facility and has been diagnosed with dementia. He believes that his nephew “took advantage” of her due to “her diminished mental health capacity.”

Due to his belief that his nephew “stole money which was rightfully meant for” his wife, Nevills allegedly became angry and decided to kill his nephew. Layton City Police officers located a sticky note with his nephew’s address in his pocket, and Nevills explained that he’d purchased a Glock handgun several weeks ago to commit the crime.

During the interview with Nevills, he stated that he was driving around looking for his nephew’s house, and would have “already killed” him if he had access to GPS on his phone. Twin Falls, ID, is roughly 200 miles away from where Nevills was found in Utah.

Nevills also allegedly told investigators that he planned to go to his nephew’s residence, kill him and his wife when they opened the door, place the gun on the ground, call 911, and wait for police to arrive.

According to court documents, after being taken into custody, Nevills said that he would kill his nephew and his nephew’s wife “in front of officers if he was able to do so.” He said that he has “nothing else to live for and is willing to do whatever it takes” to kill his nephew.

Nevills was arrested and booked into the Davis County Jail, where he is currently being held without bail.
