CONWAY, N.H. — About 60 volunteers are planning to search in the Conway area for a 15-year-old New Hampshire girl who has been missing almost three weeks.

A group called “The Mission for the Missing” is in the North Conway area and some of its members will be participating in the search for Abigail Hernandez.

WMUR-TV reports 15 teams will be assigned areas to search, working with New Hampshire Fish and Game to map out high-priority areas.

Abigail was last seen Oct. 9. She left Kennett High School at 2:30 p.m., headed home. She hasn’t been seen or heard from since.

The crews are set to search through the weekend.
