Weeks after celebrating her seven-year anniversary with her husband, a Texas woman was arrested for gunning him down at home while their children, ages 2 and 6, were present.

Morgan Leigh Sims, 33, was charged with murder in the death of Daray Vontrell Sims, 37.

According to arrest affidavits obtained by the Dallas Morning News, Morgran told a Collin County Sheriff’s Office deputy her husband, Daray, was abusive and she shot him in self-defense.

“When asked what happened, Sims stated that she had ‘had been abused, which caused me to defend myself,” read the affidavit.

Collin County sheriff's deputies were called about a disturbance at the couple's home on Friday evening. The person who called police said his sister and her husband were "arguing and fighting."

Minutes later, Morgan’s mother called 911 and said her daughter had just shot her husband.

Daray, who used to play football at Abilene Christian University, was found on the bathroom floor, covered in “copious amounts of blood,” the affidavit shows.

After Morgan was taken into custody, she told the deputy she had been abused by her husband. However, she declined to say anything further and asked for an attorney, according to an affidavit.

A semiautomatic pistol with a magazine and a live round in the chamber was found during a search of Sims’ Range Rover. It’s unclear if the Walther P22 was the weapon used in the shooting, a sheriff’s spokesman told the Dallas Morning News.

Deputies also found $9,560 in cash inside the vehicle, pills believed to be Valium and Xanax, and the family’s passports.

Additionally, deputies recovered two spent .22 cartridge casings, one live .22 cartridge, an empty container of disinfecting wipes and other used cleaning supplies at the couple’s home, court records show.

Daray Sims, according to Dallas County court records, was arrested in 2014 on suspicion of assault-family violence in DeSoto, where a grand jury ultimately declined to indict him. Morgan Sims was arrested in April 2010 on a charge of criminal mischief after allegedly scratching the paint on four cars with a rock. She pleaded no contest and was sentenced to one year of deferred adjudication supervision, records show.

Sims remains held at the Collin County Detention Center in lieu of $500,000 bail.
