Findings have been released ending months of social media speculation surrounding the death of a Massachusetts police officer.

32-year-old Officer Katelyn Tully of Haverhill, formerly of Methuen and Wilmington, passed away unexpectedly at her home on September 26th, 2025.

The Haverhill Police Department and Wayne Tracy, Chief of Police, have provided an update.

The Office of the Chief Medical Examiner has determined the cause of death to be probable cardiac dysrhythmia of uncertain etiology. 

Chief Tracy released the following:

“Officer Tully’s passing has had a profound impact on this department and the community she served. She is deeply missed by her fellow officers, friends, and family. Her dedication, professionalism, and compassion left a lasting impression on all who had the privilege to know and work alongside her. 

“We understand there has been speculation and inaccurate information circulating regarding the circumstances of her death. It is our hope that the release of these official findings will provide clarity and help put those rumors to rest, allowing Officer Tully’s family, friends, and colleagues the space to continue grieving and remembering her life and service with dignity. We respectfully ask that the public continue to keep Officer Tully’s loved ones, as well as members of the Haverhill Police Department, in their thoughts during this difficult time.”

The Haverhill Police Patrolman Association released the following statement shortly after Tully’s death:

“On September 26, 2025 we lost our sister in arms, a dedicated officer whose presence left a lasting impact on everyone she served beside. She was more than a colleague, she was family. Her quiet strength, unwavering integrity, and fierce loyalty to her duty set a powerful example for all of us. She approached each challenge with grace and resilience, never back down when others needed her the most. 

She was caring, considerate and compassionate, qualities that defined her both in and out of uniform. Whether offering a listening ear, lending a helping hand or leading with empathy, she embodied everything we hope for in an exceptional officer. Her absence leaves a void that words cannot fill, but her legacy lives on in the lives she touched and the hearts she strengthened. We will carry her memory with us always.

Her obituary stated that “on April 3, 2014, Katelyn proudly enlisted in the United States Army National Guard for a six-year enlistment. She was called to active service and bravely served in Afghanistan for six months, earning numerous awards and commendations for her courage and dedication. She was honorably discharged and returned home to continue her commitment to public service.

“Katelyn began her law enforcement career with the Haverhill Police Department. After a period with the Newbury Police Department, she returned to her home at Haverhill Police, where she remained a dedicated and respected officer. She served honorably on both the Police Honor Guard and the Military Honor Guard, consistently seeking specialized training to enhance her skills and remain current with evolving laws.”
