In the quiet town of Madison, New York, the summer of 2026 was shattered by a tragic event that claimed the lives of a respected local couple. On Friday, August 7, 2026, Steve M. Sislo, a 76-year-old man, was found deceased in his home on McCormick Road. He was discovered alongside his 72-year-old wife, Donna M. Walker-Sislo. Both had suffered fatal gunshot wounds in what authorities would soon describe as a horrific double murder and suicide.
The person responsible for this devastating act was their own son, 35-year-old Justin Sislo, who took his own life after killing his parents.
The grim discovery was made after deputies from the Madison County Sheriff's Office were dispatched to the Sislo residence for a welfare check. Upon their arrival, they were met with a strong smell of propane or gasoline and the sound of gas escaping from within the house. A look through a window revealed the bodies of two adults, prompting deputies to enter the home where they found the third deceased individual, later identified as Justin Sislo. A firearm was recovered at the scene. Steve Sislo was known in the nearby community of Rome as a philanthropist who was actively involved with the Capitol Theatre and the Chamber of Commerce.
The investigation into the tragedy quickly uncovered a troubled history concerning Justin Sislo. Less than two weeks before the fatal incident, on July 29, his parents, Steve and Donna, had paid his $10,000 bail to release him from jail. He was facing a litany of 24 charges, including felony counts of second-degree assault and second-degree strangulation, stemming from a domestic violence incident involving a girlfriend. Authorities had previously executed a search warrant at his home, seizing multiple firearms. Despite a court order prohibiting him from possessing guns, Justin Sislo managed to obtain the weapon he used in the murder-suicide. Records also indicated a history of domestic disputes, including a minor physical altercation with his father in 2024, though no charges were filed at that time. This case highlights a devastating outcome of domestic violence, where a son, with a recent and documented history of violent behavior, ultimately turned that violence against his own parents, who had just come to his aid.
