Shinelle Stills, 50, was fatally shot on the evening of October 20, 2017, during a visit to her former SeaTac, Washington home to see her 14-year-old son and care for the family pets. The visit came amid a contentious divorce; the couple had been married 17 years and Shinelle had moved out and filed for divorce months earlier.

An argument in the living room escalated when Samuel Stills retrieved a handgun from his bedroom. In the presence of his own mother, he shot Shinelle in the back, then fired additional shots after she fell. Their son came out of his bedroom and witnessed the shooting. Samuel Stills then went into a bedroom and shot himself in the chin; he survived and was taken to a hospital.

Medics pronounced Shinelle dead at the scene from multiple gunshot wounds. Samuel Stills was charged with first-degree murder with a domestic violence designation and second-degree illegal possession of a firearm and was held on $2 million bail. Does anyone have information about Shinelle, her son, or the household in SeaTac that could help clarify what led up to that evening?
