A preacher’s wife who claimed her husband abused her was convicted Thursday of voluntary manslaughter for shooting him. Mary Winkler, 33, showed no emotion as the verdict was read. Prosecutors had asked that Winkler be convicted of first-degree murder, but the jury settled on the lesser charge after deliberating for eight hours. She faces three to six years in prison, and she could be eligible for parole after serving 30 percent of that time. “The verdict was most probably just,” defense attorney Steve Farese said. The judge will sentence her May 18.
