Mark Anthony Updyke, a 33-year-old man from Longview, Texas, was shot and killed on November 29, 2014. The killing occurred during an evening in which he and his wife, Alexis Elaina Walker, had been drinking and arguing; the argument escalated and Walker shot Updyke.

Walker was arrested and charged with murder. At trial she asserted she fired in self-defense and later challenged aspects of the court’s jury instructions, but a jury convicted her and she was sentenced to 30 years in prison.

Updyke’s death devastated his family and friends and the case raised questions about domestic violence and the use of deadly force in self-defense. If anyone knew Mark, his movements that night, or has information about what led up to the shooting, please share what is known.
