SELMER, Tenn. - A preacher's wife accused of murdering her husband said Wednesday that he punched and kicked her, forced her to have sex and refused to grant her a divorce.

Testifying in her murder trial, Mary Winkler told jurors her husband, Matthew, was a smart and talented man, but could also be mean in both his actions and words.

"I just wanted out," she said. "He just could be so mean."

Her defense is expected to wrap up its case Wednesday. The defense's depiction of the Winklers' marriage contrasts radically from the description by the prosecution, whose witnesses described Matthew Winkler as a good father and husband.

Shortly after they were married, "he just got me down and told me that I was his wife and we were family now, and he just screamed and hollered," Mary Winkler said.

She testified that her husband once kicked her in the face during an argument, and that he also hit her in the face, pushed her down and hit her with a belt.

Mary Winkler said he kept her away from her family and criticized her appearance. "I was fat, hair wasn't right. With the girls, if something went wrong, it was my fault. If it rained, it was my fault," she said.

The defense also showed the jury a pair of white platform-heel shoes and a wig that Mary Winkler said her husband wanted her to wear during sex. She said he also asked her to look at pornographic photos before sex and wanted sex she considered unnatural.

Mary Winkler talked quietly with her eyes downcast while testifying on the topic. She identified pornographic pictures as those she saw on her husband's computer, and those photos were entered as evidence.

Matthew Winkler, 31, was found fatally shot in the parsonage where the family lived in March 2006. A day later, his wife was arrested on the Alabama coast 340 miles away, driving the family minivan with her three young daughters inside.

Mary Winkler, 33, could be sentenced to up to 60 years in prison if convicted of first-degree murder. But a psychologist who testified for the defense said Mary Winkler could not have formed the intent to commit a crime because of her compromised mental condition.

Dr. Lynn Zager testified that Mary Winkler suffered from mild depression and post-traumatic stress disorder, which started at age 13 when her sister died and was worsened by her husband's abuse.

The disorder made it more likely that Mary Winkler would have "dissociative episodes" in which she lost track of her ability to think and feel, as though she were living in a fog, Zager said.

The defense has said Mary Winkler intended to hold her husband at gunpoint only to force him to talk about the incident involving their 1-year-old daughter, Breanna, and that the shooting was accidental.

A forensic pathologist testified that Matthew Winkler was shot in the back.

Several witnesses for the prosecution said they never saw any sign that Matthew Winkler was abusing his wife. The couple's 9-year-old daughter, Patricia, testified that she had a good father and she never saw him mistreat her mother.

Last week, prosecutors played an audiotape in which Mary Winkler acknowledged shooting her husband, telling investigators her "ugly came out." She told authorities that her husband criticized her constantly and that she got tired of it and just "snapped."

Tabatha Freeman, Mary Winkler's younger sister, said Tuesday she noticed changes in her sister after she got married in 1996. She said Matthew Winkler controlled everything his wife did, preventing her from making any decisions and isolating her from her family.

"A very bubbly, outgoing sister became very subdued," Freeman said.
