ELMO, Texas — UPDATE [Dec. 27] — 26-year-old Auston Armstrong now faces a second-degree felony manslaughter charge, in addition to upgraded felony assault charges, in connection with a Christmas Eve domestic-violence incident that left two hospitalized and another who tragically died.

On Friday, police charged Armstrong with manslaughter in connection with the death of 20-year-old Brittani Davis.

A previous misdemeanor assault charge was withdrawn and a second-degree felony aggravated assault causes serious bodily injury has been filed in its place.

An aggravated assault with a deadly weapon charge also includes a family violence stipulation which makes that charge a first-degree felony.

The male stabbing victim remained hospitalized in stable condition, according to police. A second male victim was hospitalized with facial fractures and other superficial injuries.

An autopsy is still pending, as of Friday afternoon.

Armstrong's total bonds are expected to be set at $800,000.

Around 11 p.m., on Tuesday, December 24, 2019, the Kaufman County Sheriff's Office responded to a reported stabbing in the 9400 block of County Road 312 in the Elmo area.

There, police discovered a male suffering of apparent stab-related injuries and a female who had suffered an apparent head injury.

The female, identified by police as 20-year-old Brittani Davis of Elmo, Texas, was transported to an area hospital where she was pronounced deceased.

The alleged suspect, identified as 26-year-old Auston Bryce Armstrong, was arrested and charged with aggravated assault with a deadly weapon and assault causes bodily injury to a family member. He is being held at the Kaufman County Jail and is awaiting arraignment and a bond hearing.
