Guilty verdict in 2018 murder south of Bluff
A federal jury convicted a San Juan County man on May 18 for murder in the second degree while within Indian Country and use, carry and discharge of a firearm during a crime of violence.
According to the trial, Perry Maryboy, age 59 of Bluff, unlawfully shot and killed 31-year-old Antonio Montowine on April 13, 2018.
Court documents allege Maryboy, who was parked on the side of the road at the intersection of Country Road 443 and Summerhouse Road, escalated an argument with Montowine after being told to leave the area by the victim, who drove up behind him.
Maryboy exited his truck and grabbed a revolver. He fired two shots, each allegedly intended as warning shots, but the second shot struck the victim in the back of the head.
The victim died on scene in front of his common law wife and her 7-year-old child. Maryboy then fled the scene in his truck.
The vehicle was described as a white truck with 4x4 decals on the side of the truck.
According to charging documents, Montowine’s wife spotted the truck on the Navajo Nation four months later.
She provided FBI agents with a license plate number, which was registered to the family of Maryboy.
“The defendant acted with complete recklessness,” said Assistant United States Attorney Mark Hirata during trial. “If firing a bullet to the back of a person’s head isn’t a crime of violence, I don’t know what is.”
Sentencing is scheduled for August 4 before U.S. District Court Judge David Nuffer.
U.S. Attorney Trina A. Higgins made the announcement.
The case was investigated jointly by the Federal Bureau of Investigation (FBI) Monticello Field Office, Navajo Nation Police Department and Navajo Nation Criminal Investigations.
Assistant U.S. Attorneys, Mark Y. Hirata, Angela Reddish-Day, and Stephen Dent are prosecuting the case.
