FORT WORTH, TX – The day after Christmas turned tragic for a Fort Worth family when a dispute escalated to violence, leaving 58-year-old Tony Graham dead in the home he shared with his niece and other roommates.
Authorities say the deadly confrontation occurred just after noon on December 26 inside a house on the 3400 block of Wade Avenue. Graham, who lived in the crowded residence with several tenants, reportedly became embroiled in an argument with his 32-year-old niece, Ashley Siebenaller. Relatives say an ongoing dispute over household responsibilities that day centered on a request for Siebenaller to cook a meal.
According to investigators, the situation spiraled when Graham allegedly told Siebenaller she needed to “start cooking,” then locked her out of the house earlier in the day. Tensions between the pair, who shared space in the home’s living room, were well-known among the other tenants.
Witnesses inside the residence heard a heated exchange and soon found Graham collapsed on the floor, suffering from a single stab wound to the chest. The knife used in the attack was discovered nearby, while Siebenaller was observed sitting quietly on the couch. The roommates said Graham, despite his injuries, instructed them to call emergency services.
First responders arrived shortly after 12:18 p.m., but despite their efforts, Graham could not be revived. Meanwhile, witnesses told officers that Siebenaller appeared unresponsive, at first declining to speak and communicating through written notes. She initially denied knowledge of the events that led to her uncle’s death.
Following her arrest, Siebenaller continued to deny involvement during early police questioning. However, in a subsequent interview on December 30, she became more communicative and eventually admitted to stabbing Graham after arguing with him over the meal, police say. She reportedly claimed Graham had stabbed her in the mouth prior to the incident, though officers observed no injuries to support this assertion.
Siebenaller and Graham had a history of friction, according to statements from those familiar with the living arrangement. The residence, managed by a separate leaseholder, rented out rooms and shared spaces to multiple individuals, adding to an environment that witnesses described as tense.
On January 2, police received an additional report from a roommate alleging that Siebenaller was seen holding a knife outside their bedroom door. That incident did not result in injury but heightened concerns among residents about her behavior following Graham’s death.
Siebenaller was arrested without resistance earlier this week and charged with murder. She is currently held at the Tarrant County Jail, with no bond set as the investigation into Graham’s death continues.
Tony Graham is remembered by family as a longtime Fort Worth resident known for his sense of responsibility and commitment to those in his circle, a man whose life was cut short in a moment of family discord that stunned all who knew him.
