NORTH CONWAY, N.H. — By air, land and water, crews continue to search for a missing North Conway girl who vanished Wednesday.

Local, federal and state officers have been joined by volunteers in the search for 14-year-old Abigail Hernandez. They’re paddling local waterways, flying over the area, handing out posters at roadblocks and carefully marching in lines through the woods at the southeast corner of the White Mountains.

At a briefing late Friday, Senior Assistant Attorney General Jane Young repeated what authorities have said all along: They have found nothing suspicious yet and the case is being treated as a missing person investigation.

Hernandez, who turns 15 Saturday, left Kennett High School around 2:30 Wednesday afternoon and police believe she made it home. But when her mother arrived home, the girl was gone.
