Katie Elizabeth Arnold, 36, was shot to death through a bathroom window at her Deck Lane home in Blountville, Tennessee, on January 18, 2023. Her mother discovered the scene after hearing a disturbing noise. In the days before the killing, Arnold had told others she feared for her safety and alleged that her recently ended relationship with 32-year-old Donald Britt included stalking and that Britt had been involved in a robbery.

Investigators identified Donald Britt as the primary suspect. A witness reported giving Britt a ride to an area near Arnold’s residence on the night she was killed. After the shooting Britt went to a nearby home on Stevenson Hill Road, where 56-year-old Barry Countiss was shot and killed and his vehicle stolen. A police pursuit of the stolen vehicle ended the next day in Johnson City, where Britt was taken into custody.

The case raises questions about the lead-up to the killings and the opportunities to intervene once Arnold reported feeling threatened. If anyone knew Katie, her routines, or saw suspicious activity near Deck Lane on January 18, what information can be shared with investigators?
