Overview
- Tully’s retirement took effect Wednesday, April 8, and the agency said he received an honorable discharge.
- He previously led the State Police detective unit assigned to the Norfolk County district attorney’s office and supervised the 2022 probe into Boston officer John O’Keefe’s death.
- He later testified in Karen Read’s case, which ended with a 2024 mistrial and a 2025 acquittal on the most serious charges alongside a drunk driving conviction.
- An internal review found he failed to supervise or discipline unit members over inappropriate text messages, leading to a penalty of six forfeited leave days and a transfer out of the Norfolk unit in October 2024.
- Other investigators also faced consequences after the texts surfaced, including the firing of lead trooper Michael Proctor and the reassignment of Sgt. Yuri Bukhenik, while a pending federal lawsuit by Read names Tully as a defendant with depositions expected.
