Ruth Etting (November 23, 1897 - September 24, 1978) was an American singing star and actress of the 1920s and 1930s, who had over 60 hit recordings and worked in stage, radio, and film. Known as "America's sweetheart of song", her signature tunes were "Shine On, Harvest Moon", "Ten Cents a Dance" and "Love Me or Leave Me". Her other popular recordings included "Button Up Your Overcoat", "Mean to Me", "Exactly Like You" and "Shaking the Blues Away". As a young girl in Nebraska, Etting had wanted to be an artist; she drew and sketched everywhere she was able.

Etting fell in love with her pianist, Myrl Alderman, who was separated from his wife. In January 1938, she began receiving threatening telephone calls from Snyder, who initially claimed Etting withheld assets from him when the divorce settlement was made. Though the couple was divorced, Snyder was also upset because of reports that she was seeing another man. Snyder told Etting that he would come to California and kill her. When Snyder telephoned and found Etting unavailable, he told his daughter Edith that he "would fix her ticket, too". He called again that evening; this time Etting took the call with her cousin, Arthur Etting, listening on an extension. Etting requested police protection after the telephone call and arranged for private protection. Apparently believing the danger was over when Snyder did not appear soon after his telephone call, Etting released her bodyguards a few days later.  On October 15, 1938, Snyder detained Myrl Alderman at a local radio station and forced the pianist to take him to his former wife at gunpoint. In the house at the time were Etting and Edith Snyder. Edith, Snyder's daughter by a previous marriage, worked for Etting and remained living with her after the divorce. Snyder held Etting and Alderman at gunpoint; when told his daughter was in another part of the house, he made Etting call her into the room. Snyder said he intended to kill all three, and told them to be quiet. When Myrl Alderman attempted to speak, Snyder shot him. Snyder then told his ex-wife, "I've had my revenge, so you can call the police."  Snyder claimed Myrl Alderman pulled a gun and shot at him first and that his ex-wife would not file charges against him because she still loved him. He also claimed he was drunk when he made the telephone threats to Etting in January 1938, saying that at the time his intentions were to kill both his ex-wife and himself. Ruth Etting said that the only gun in the home belonged to her, and after the shooting of Alderman, she was able to go into her bedroom and get it. Upon seeing Etting's gun, Moe Snyder wrested it away from her; it landed on the floor. Snyder's daughter, Edith, picked it up and held it on her father, shooting at him but hitting the floor instead. During a police reenactment of the shooting three days later, Edith Snyder said that she fired at her father to save Ruth Etting, weeping as she continued, "I don't yet know whether I am sorry I missed my Dad or whether I am glad". Snyder was accused of attempting to murder his ex-wife, his daughter, and Etting's accompanist, Myrl Alderman, the kidnapping of Alderman, as well as California state gun law violations.
