The Post cited a grand jury subpoena issued earlier this month in Los Angeles and stated that people close to Irsay had been contacted. Irsay, who spent long stretches in California, died at the Beverly Hills Hotel. The Post has reported that Haroutunian was also staying at the hotel and treating Irsay before his passing. Irsay spoke publicly about his experience with substance abuse, including multiple overdoses and one that nearly cost him his life. His three daughters — Carlie Irsay-Gordon, Casey Foyt and Kalen Jackson — have assumed ownership of the Colts after his death. The Colts said they are “aware” of the investigation, The New York Times noted. From @TheAthletic: The Indianapolis Colts said that they are “aware” of an FBI investigation into the death of the team’s former longtime owner, Jim Irsay, last year. Federal investigators are examining Irsay’s drug use — “prescription” and illegal. https://t.co/L88hd3MaK1 — The New York Times (@nytimes) January 23, 2026 CBS Sports shared further info: In August, The Washington Post published an extensive report citing multiple people maintaining that Irsay, who claimed to have defeated his addiction to pain meds, had not only relapsed, but overdosed multiple times in the last five years. The Post acquired images of pill bottles that showed Haroutunian had prescribed Irsay more than 200 pills days before the Colts owner had two overdoses in less than two weeks back in 2023, including one episode that left him hospitalized for four months. According to multiple people who witnessed the injections, Haroutunian then added ketamine to Irsay’s treatment plan. Irsay was one of the most recognizable owners in the NFL at the time of his death. He became the youngest general manager in NFL history at the age of 24 back in 1984, then became the youngest NFL owner at 37 when he took over the franchise following his father’s death in 1997. Under Irsay’s leadership, the Colts made 16 playoff appearances, took home two AFC titles and won Super Bowl XLI.
