BRATTLEBORO, Vt. (AP) - A Brattleboro woman is hoping a newly formed New Hampshire cold case unit can help find her daughter and granddaughter who have been missing for almost nine years.

Mary Lewis says she hopes the unit will be able to learn what happened to her daughter and granddaughter.

Then 36-year-old Tina Sinclair of Chesterfield, N.H., and her 15-year-old daughter Bethany haven't been seen since Feb. 4, 2001.

Tina Sinclair's then-boyfriend was the last person to see the two alive.

The two are listed as missing persons.

Earlier this month New Hampshire Attorney General Michael Delaney announced the formation of the state's first cold case unit.

Lewis tells the New Hampshire Union Leader she wants to know what happened.
