Mary Winkler showed no emotion as the verdict was read, but later she hugged her family and her attorneys.
Prosecutors had sought a first-degree murder conviction, but the jury settled on the lesser charge after deliberating for eight hours. She faces three to six years in prison, but she would be eligible for parole after serving about a third of the sentence.
If Winkler, 33, had been convicted of first- or second-degree murder, she would have gone to prison for at least 12 years and maybe for the rest of her life. Her lawyers said Mary Winkler's testimony on the stand was decisive.
"They had to hear it from Mary; there was no other source," defense attorney Steve Farese said.
Winkler told jurors in powerful testimony Wednesday that her husband, Matthew, abused her physically and sexually, but she said she did not pull the trigger and the shotgun went off accidentally as she pointed it at him.
The prosecution said it was ludicrous to suggest the shooting was an accident. Assistant District Attorney General Walt Freeland said bank managers were closing in on a check-kiting scheme that Mary Winkler wanted to conceal from her husband.
Matthew Winkler, a 31-year-old preacher at the Fourth Street Church of Christ, was found in the church parsonage fatally shot in his back in March 2006. A day later, his wife was arrested on the Alabama coast, driving the family minivan with their three young daughters.
Prosecution witnesses described Matthew Winkler as a good husband and father, and the couple's 9-year-old daughter testified she never saw her father mistreat her mother. Mary Winkler also said under cross-examination that her husband did nothing for which he deserved to die.
"At the end of the day, we're left with the memory of Matthew Winkler," said defense attorney Leslie Ballin. "And even though there have been a lot of negative things said about him in this trial, there were some good things, too, and you heard that from Mary."
Matthew Winkler's father Dan Winkler, who is also a preacher at a Church of Christ in Huntingdon, thanked the jury and thanked God for being "our rock and our shield" during the trial.
"We're very grateful for the privilege and honor that was ours to be the parents of Matthew Brian Winkler," he said. "And we treasure the memory of the love that he had for his family, for his Lord, for his church, for us his parents."
The prosecution released a statement that said, "We want the Winkler family to know that our thoughts and prayers continue to go out to them for the loss of their son, brother and father, Matthew Winkler."
The couple's three daughters - ages 2, 7 and 9 - are in the custody of his parents, but the defense attorneys said Mary Winkler hopes the verdict will allow her to be reunited with her daughters in the future. Dan and Diane Winkler have filed a wrongful death lawsuit against Mary Winkler.
She will be sentenced May 18, but is free on bond until then. She will continue living with a friend in McMinnville, about 65 miles southeast of Nashville. Voluntary manslaughter suggests the crime was committed in an irrational state and premeditation is not necessary for a conviction. A psychologist testified Mary Winkler could not have formed the intent to commit a crime because of her compromised mental condition. Dr. Lynne Zager said she suffered from mild depression and post-traumatic stress disorder, which started at age 13 when her sister died and got worse because her husband abused her. The defense attorneys said the jury convicted Mary Winkler of a lesser sentence because they believed her stories of abuse. Mary Winkler testified her husband punched her in the face, kicked her at times and refused to grant her a divorce. The prosecution said there was no medical evidence of abuse, but Mary said she never told anyone and hid the bruises. Speaking about their sex life, Mary Winkler spoke quietly and hesitantly, with eyes downcast. She said her husband forced her to view pornography, dress "slutty" and have sex she considered unnatural. The defense showed the jury a pair of white platform-heel shoes and a wig Mary Winkler said her husband wanted her to wear during sex. Pornographic photos she identified as coming from their home computer were entered as evidence. The Winklers were married in 1996. They met at Freed-Hardeman University, a Church of Christ-affiliated school in Henderson. Mary took education classes, and Matthew took Bible classes. Neither graduated. The jury was made up of two men and 10 women, one of whom said she had been a victim of domestic abuse. They have been sequestered at a motel during the trial, which began April 9.
