On Thursday afternoon, Auston Armstrong was found guilty of one count of aggravated assault causing serious bodily injury with a deadly weapon to a family member. He was found guilty after stabbing his brother on Christmas Eve of 2019.
The jury verdict came in Kaufman’s 86th district court after almost eight hours of deliberation that began Wednesday afternoon.
Armstrong also faced a manslaughter charge in the death of his brother's girlfriend, who died on Dec. 25.
Armstrong, who was 26 at the time, was at a family gathering on Christmas Eve in Elmo that resulted in the death of Brittani Davis, who was 20. At the time, police said they believed she was shoved during the incident and struck her head. She was the girlfriend of Armstrong’s brother, Tyler, and died the next day. Tyler Armstrong was treated and in stable condition after the stabbing. Another victim injured during the evening also recovered.
In February, Armstrong was indicted by a Kaufman County grand jury on one count of manslaughter, a second-degree felony; one count of aggravated assault with a deadly weapon, a second-degree felony; and one count of aggravated assault causing serious bodily injury involving family violence, a first-degree felony.
Armstrong had been offered a plea deal of 30 years for the three offenses, but declined the offer, according to a source close to the case.
Judge Casey Blair is presiding over the trial.
Kaufman County sheriff’s deputies responded to the disturbance at 11 p.m. on Christmas Eve in a home in the 9400 block of CR 312 in Elmo, according to a press release from the sheriff’s office that was issued a few days later. Armstrong was held in custody on an $820,000 bond and had remained in custody since the death of Davis.
Court records show Armstrong had previous arrests for resisting arrest and driving while intoxicated.
The obituary for Davis said her death was the loss of a shining light for everyone who knew her. She loved band in school and had been a member since sixth grade. She was a dental assistant for Sherry Lane Dental and was a manager of an accessories business, Rustic Cactus, in Terrell. Her obituary listed survivors as Tyler Armstrong and her parents, Tamara Rhoades and Tommy Davis, Jr. of Wills Point, along with many family members.
