A wife who could no longer tolerate the abuse from her husband has ended up shooting him to death.

Brittnay Ryals Paonessa, 27, is charged with fatally shooting her Army sergeant husband just days after he obtained an emergency protection of abuse order against her, alleging she was “very mentally ill” and unstable.

She is accused of gunning down Brandyn Lloyd Paonessa on Thursday in the front yard of a home in Phenix City, WTVM reports.

Paramedics tried to save the father of four, but Brandyn, a 26-year-old infantryman at Fort Benning who was shot once in the chest, was pronounced dead at the scene. Investigators recovered a shotgun from the home and have preserved the weapon as evidence, deputies said.

Court records obtained by the station in Alabama show that the soldier had taken steps to protect himself days prior to his alleged murder, filing for and obtaining an emergency protection from abuse order against his wife just three days earlier, on Monday.

Brandyn accused his wife of being “very mentally ill” and “very unstable,” claiming she had refused to get treatment at a rehab center. He also accused Brittnay of stalking him, as well as his family and friends, and trying to ruin his job as an infantryman after he joined the Army in September 2013.

Brandyn also accused his wife of driving a truck into the couple’s home “3 feet from our children,” according to the filing.

The couple, who had been married since 2013, had three children together and Brittnay has a child from a previous relationship, Al.com reports.

Fort Benning officials confirmed Brandyn’s death in a statement, saying he was assigned to Task Force 1-28, 3rd Infantry Division, and had two combat tours of duty in Afghanistan.

“The cause of his death remains under investigation,” Fort Benning officials said.

Investigators did not provide any details on a possible motive in the slaying, WSFA reports.

Brittnay, who was charged with murder Friday, was being held on $150,000 bond at the Lee County Detention Facility. It’s unclear if she’s hired an attorney.

Court records obtained by Al.com also show that Brandyn was arrested last year and charged with third-degree domestic violence after his wife accused him of punching her in the stomach after she looked through his cellphone. The charge was later dismissed at Brittnay’s request, Al.com reports.
