Cold Case Unit Leverages New Technology in Investigation of 2001 Disappearance of Tina and Bethany Sinclair

Concord, NH - Attorney General John M. Formella and Colonel Mark B. Hall of the New Hampshire State Police announce, on behalf of the New Hampshire Cold Case Unit, that Tuesday, February 3, 2026, marks the 25th anniversary of the disappearance of Tina Sinclair and her daughter, Bethany Sinclair, from their home in Chesterfield, New Hampshire.

Tina Sinclair and her daughter, Bethany, were last seen together during the weekend of February 3-4, 2001. Prior to their disappearance, they resided at a home on Mountain Road in West Chesterfield. Despite extensive searches conducted over the past two decades, including operations at their former residence and diving operations in the Connecticut River, their whereabouts remain unknown.

The New Hampshire Cold Case Unit remains actively engaged in this investigation. Investigators are utilizing advancements in technology developed over the past 25 years to reexamine evidence and pursue new leads. The passage of time can create new forensic opportunities, and the Unit is committed to applying every available resource to resolve this case.

"Time can be an adversary in an investigation, but it can also be an ally," said Senior Assistant Attorney General R. Christopher Knowles, Chief of the New Hampshire Cold Case Unit. "Over a quarter century, relationships change, friendships fade, and the weight of a secret can become too heavy to carry. We know there are people who have information about that night in February 2001. We are asking them to finally break their silence and help bring answers to a family that has waited far too long."

On this significant anniversary, the family of Tina and Bethany Sinclair has released the following statement:

"On February 3, 2026, 25 years will have passed since the disappearance of two women from their West Chesterfield NH home. Tina was 34 at the time and would be turning 60 this year. Bethany was a teenager of 15 and would be turning 41. The time has passed and life has moved on for so many of us. Tina and Bethany remain in our hearts and memories; however, there are so many unanswered questions. Where did they go on that cold February night 25 years ago. Does anyone know? Does anyone remember anything that may help us solve this cold case and end the heartache. If you can contribute anything, no matter how minor you think it may, be please reach out to the New Hampshire Cold Case unit. On behalf of the family friends and loved ones of Tina and Bethany we thank you for anything that you can do to help us find the answers."
