Lora Renae Karras, 30, was shot and killed at her home in Scranton, Arkansas, on March 19, 2014. She was a mother of three, worked full-time at a Walmart Distribution Center and was a student at Arkansas Tech University at Ozark. Three children, ages 15, 11 and 9, witnessed the shooting.

Law enforcement identified Lora’s ex-husband, Joshua Johnson, then 40, as the person responsible and charged him with first-degree murder. Johnson’s family reported he had served overseas in Afghanistan and Iraq and believed he suffered from post-traumatic stress syndrome; Johnson underwent mental evaluations before trial.

A Logan County jury later convicted Johnson of first-degree murder. Did anyone in the Scranton area know Lora or the family and have information that could shed more light on what happened?
