A Vancouver woman was sentenced Wednesday to more than 10 years in prison for attempting to shoot her then-husband to death while he was lying in bed.In an agreement with prosecutors, Gayle Bethke, 62, pleaded guilty Wednesday in Clark County Superior Court to one count of second-degree attempted murder. In exchange, Deputy Prosecutor Jennifer Nugent dropped a charge of first-degree attempted murder, which carries a sentence of more than 16 years in prison.Bethke apologized Wednesday to her ex-husband, Roger Bethke, and his two sons. She said her actions spiraled out of control during a drinking binge.“I was on a downward spiral, and I felt hopeless,” she said Wednesday.“I’m just glad no one is hurt,” she added.Bethke admitted to being an alcoholic and to feeling suicidal on the night of Sept. 21, 2012, when she attempted to kill her husband at their home in the Burnt Bridge Creek neighborhood. She said she had gone to see a mental health counselor prior to the incident.That night, she said, she and Roger Bethke had dinner together and then walked their four dogs.Later, they got into a disagreement while they were in bed discussing getting a divorce, Nugent said.Roger Bethke heard her go downstairs, return to the bedroom and then rummage for something inside a plastic bag, the prosecutor said.She then approached him, yanked the blanket off, and pointed a pistol at his head, Nugent said. Roger Bethke was able to wrestle the gun away, but she repeatedly threatened to kill him.
