A bizarre murder case out of upstate New York just ended with a 33-year-old woman sentenced to 25 years to life in prison—after she tried to convince a jury that a horse killed her mother.
Ariela Thran of Fulton was convicted of murdering her mother, Patricia “Allison” Halverson, in December 2023 at Halverson’s rural home in Solon. In an unusual twist, Thran attempted to dodge responsibility by blaming her mom’s death on the family’s horses.
Prosecutors say Halverson’s body was found near a piece of farming equipment, left exposed to the elements. With no murder weapon recovered, Thran leaned into a strange defense: the horses did it.
Her legal team even brought in an equestrian expert who testified during the March trial that horses can cause fatal harm “if they choose to.” Adam D’Agostino, director of Alfred University’s equestrian program, claimed the horses were free to roam the property and that proper safety protocols weren’t in place—especially for stallions.
“I do not feel the consistent industry practices were used on the farm,” D’Agostino told the court. He admitted, however, that he never met the horses or visited the scene.
He argued that the animals could have trampled or stomped Halverson, suggesting her injuries could’ve been caused by natural equine behavior. But the prosecution wasn’t buying it.
A forensic pathologist who testified for the state said Halverson had been struck in the head at least 16 times—injuries that didn’t line up with any horse attack. She also had a cut on her forehead and a bruise on her eyelid, further supporting the case for a violent assault, not a tragic farm accident.
Cortland County DA Patrick Perfetti admitted the case was tough. “This was a particularly challenging case, as no murder weapon was recovered,” he said. “But the digital evidence—and the timing of it—was key.”
Prosecutors described the killing as the tragic result of a fractured family. “This was a sad case,” added lead prosecutor Richard Van Donsel. “The breakdown of a family like this is tragic.”
Thran faced 10 years to life but was handed the maximum sentence. The small town of Solon, about 150 miles west of Albany, is still reeling from the case—especially as the defense’s “killer horse” theory made national headlines.
She giru what she deserves .Maybe while in prison she will repent .To murder you mother and then blame a horse who probably loved her mothe,r is sick.
