FORT WORTH, TX – A holiday gathering in a quiet Fort Worth neighborhood took a tragic turn when a dispute over cooking escalated into a deadly confrontation, leaving a 54-year-old man dead and his niece charged with murder.
Authorities say Ashley Siebenaller, 32, is accused of fatally stabbing her uncle, Tony Graham, on Dec. 26 inside a shared home on Wade Avenue. The alleged stabbing happened in the aftermath of an argument that began earlier in the day, police reports indicate.
Investigators allege the day began with tension festering between the two. According to statements given to police, Graham reportedly became frustrated over a meal and told Siebenaller she “needed to start cooking.” During the dispute, Graham allegedly locked his niece out of the house, intensifying the situation.
Witnesses living in the multi-tenant home recalled hearing the altercation erupt just before noon. Moments later, they discovered Graham crumpled on the floor, a single stab wound visible in his chest. Nearby, Siebenaller was found sitting on the couch by a bloody knife, authorities said.
Despite the chaos, Graham managed to instruct others to notify emergency services before losing consciousness. Police officers were dispatched to the address and encountered Siebenaller, who appeared withdrawn and non-communicative as they attempted to question her at the scene.
Officers resorted to communicating with Siebenaller in writing, but initially, she denied any knowledge about the incident. She refused to acknowledge involvement and claimed no recollection of how Graham was stabbed, police documents show.
Detectives met with Siebenaller four days later for a follow-up interview, during which she was more lucid and expressive. Again, she denied responsibility, but investigators say she ultimately admitted to attacking Graham after he reportedly provoked her over a meal.
According to Siebenaller’s account, she and Graham both occupied the living room of a house that was subdivided and rented to multiple tenants. She told officers her uncle’s remarks about her not cooking and earlier actions in locking her out had angered her severely.
During questioning, Siebenaller claimed Graham had first stabbed her in the mouth. However, police noted there was no evidence or injury consistent with such an allegation.
Just days after the fatal incident, another resident of the house contacted law enforcement, reporting that Siebenaller had been standing outside their bedroom holding a knife. This prompted a further police response.
Siebenaller was arrested this week without resistance and charged with murder. She remains in custody at Tarrant County Jail, with no bond established as of Wednesday.
