At the upcoming trial of a man accused of beating, strangling and burning a Crow Agency woman last year, prosecutors will present to jurors the dying words of the victim, according to a trial brief filed this week. 19-year-old Dimarzio Sanchez is charged with first-degree murder for the death of Roylynn RidesHorse last year.

The trial is set to begin on Monday in U.S. District Court in Billings. Sanchez is one of three people charged in connection with the murder. Frank Sanchez and Angelica Jo Whiteman have already accepted plea agreements, which include for Whiteman the requirement that she testify against Dimarzio Sanchez at his trial. According to court documents, RidesHorse accepted a ride home from Whiteman in April of 2016. She was strangled, stripped naked and set on fire in a remote area of the Crow Reservation.
