On November 20, 2015, 49-year-old Joel Rodriguez of Quincy was shot and killed at his workplace, Callahan Manufacturing, in Royal City, Washington. A second man from Soap Lake was wounded in the same attack; he was shot twice in the back and once in the arm and survived.

Investigators identified Royal City resident Eduardo Ibarra Valencia as the shooter. A witness reported seeing Ibarra Valencia acting nervously before he approached Rodriguez and fired a semi-automatic weapon. In the days before the incident he had expressed fears that others were out to harm him and had shown a .40 caliber handgun to a coworker, saying it was for his protection; his girlfriend reported he was having trouble with coworkers.

Ibarra Valencia was arrested and initially charged with first-degree murder and attempted first-degree murder; he underwent a competency evaluation and mental health examinations. Does anyone who worked at Callahan Manufacturing or knew Joel have information that could shed light on what led to the shooting?
