Cold Case Unit

Recognizing the enormous hole the loss of a loved one leaves in the life of a family, the District Attorney Marian Ryan created a new Cold Case Unit.

The work of the Cold Case Unit is all encompassing. Prosecutors working with the unit re-examine existing evidence and utilize the latest investigative techniques and technology to examine uncharged cases across the County.

This initiative reflects District Attorney Ryan’s unwavering commitment to Middlesex County’s oldest cases. In January, 2019, the Office solved the oldest case in their history, the 50 year old murder of a Harvard graduate student, Jane Britton, through the use of improved DNA testing measures. In bringing this case to conclusion investigators were able to provide answers to Jane’s brother and many of her friends who were alive and still haunted by her tragic death.

Collaboration with the community is also a primary focus of the unit, recognizing that the public plays a critical role in moving unsolved investigations forward.

If members of the public believe that they have information about any unsolved homicides they are encouraged to contact the Massachusetts State Police assigned to the Middlesex District Attorney’s Office at 781-897-6600.
