Jurors this week found a Montana man guilty of aiding and abetting first-degree murder for his role in the June 2016 death of Roylynn Rides Horse.

Dimarzio Sanchez, 20, of Busby, was one of three defendants charged in connection with inflicting the torture that resulted in her death more than two months after the initial attack.

As KULR reported, Sanchez was with his brother and a friend when they met Horse at a bar on April 17, 2016, and left with her that night.

The trio then began torturing the 28-year-old Crow Agency woman in an attack that included a beating and strangulation and ended when they set her on fire.

Horse remained hospitalized with third-degree burns until her death on June 28, 2016.

The two others involved, Frank Sanchez and Angelica Whiteman, pleaded guilty to reduced charges earlier this year in exchange for testimony against Dimarzio Sanchez.

During this week’s trial, they both claimed there was no motive for the brutal attack, the Billings Gazette reported.

A jury deliberated Thursday and returned a guilty verdict that could result in a 100-year sentence for Dimarzio Sanchez.

His brother could serve 15 years after pleading guilty in March to misprision of a felony and accessory to injury after the fact. He also faces fines totaling $125,000 and three years of supervised release following his incarceration.

Whiteman pleaded guilty to aiding and abetting first-degree murder and could face a life sentence in addition to five years of supervised release and $250,000 in fines.

After three days of testimony in the trial of Dimarzio Sanchez, jurors reached a verdict within hours.
