Christen DeMars was 22 when she died of a gunshot wound on March 24, 2015, in her Spokane apartment at 2928 E. Diamond. A neighbor called 911 after hearing a gunshot and yelling; that neighbor later found Christen unresponsive on her bed. She was taken to Holy Family Hospital, where a gunshot wound above her right hip was discovered and she later died surrounded by family. Syringes and drug paraphernalia were found in the apartment, and first responders initially thought she was overdosing.

Police identified her 28-year-old boyfriend, Cameron D. Keith, as a person of interest. Christen had an active protection order against him, and her mother told police he was abusive and that Christen had been trying to end the relationship. A .45 caliber handgun and ammunition were recovered in the apartment. Keith was arrested April 2, 2015, on an outstanding warrant and charged with second-degree murder; he told investigators he fell asleep after using heroin and suggested Christen may have rolled onto the gun, but investigators said the bullet trajectory and lack of gunpowder residue on her clothing did not support that account. If anyone knew Christen or has information about what happened that morning, please share what you know.
