A Texas woman faces charges after allegedly stabbing her uncle to death the day after Christmas, following an argument over meal preparations. Authorities report that the uncle had told her she needed to cook and subsequently locked her out of their home.

According to online jail records, Ashley Siebenaller, aged 32, is charged with murder for the incident that occurred on December 26. As detailed in an arrest affidavit obtained by The Dallas Morning News, Siebenaller is accused of stabbing her uncle, Tony Graham, once in the chest inside their Fort Worth residence, claiming the act was accidental.

The affidavit reveals that other residents in the home overheard the altercation and discovered Graham on the floor, with a bloody knife on a nearby couch. Siebenaller was reportedly seated on the couch next to the weapon.

Graham instructed the witnesses to contact emergency services. Police arrived at the location on the 3400 block of Wade Avenue at 12:18 p.m. on that Friday, finding Siebenaller acting as though she was unable to speak, according to the affidavit.

When an officer attempted to communicate with Siebenaller by writing, she claimed to be unaware of what transpired and denied any involvement in Graham’s stabbing.

A follow-up interview was conducted with Siebenaller on Dec. 30 and police say she was able to talk and communicate much more clearly than she did at the scene. She again denied being involved in the stabbing before eventually confessing to killing Graham following an argument over her fixing him a meal, the affidavit says.

According to police, Siebenaller said that she and Graham lived together in the living room of the residence, which was being leased by another person who rented out spaces throughout the home to several people.

Siebenaller claimed that Graham “p—ed her off” after he “told her she needed to start cooking,” the affidavit alleges. He also allegedly locked Siebenaller out of the house earlier in the day, according to police.

Siebenaller told detectives that Graham stabbed her in the mouth before she killed him, but she had no injuries or marks on her face to support this, the affidavit says.

Days later, Fort Worth police received a report on Jan. 2 from a roommate in the home who alleged that Siebenaller was standing outside their bedroom door while wielding a knife. She was taken into custody this week without incident and charged Monday.

Siebenaller is being held at the Tarrant County Jail with no bond set.
