CONCORD, N.H. (AP) — Police say a New Hampshire teenager who disappeared nearly two months ago on her way home from school has sent a letter to her mother.

The FBI and the state attorney general's office say 15-year-old Abigail Hernandez wrote her mother a letter postmarked October 23, 2013 that was received November 6, 2013.

Police say they have verified the letter is authentic. They are not releasing it.

Law enforcement officials say the letter has given them hope, but they fear for her safety.

Abigail was last seen on October 9th after leaving Kennett High School in North Conway. Police have said she walked her normal route toward home and sent several texts to a friend between 2:30 and 3 p.m. At first, police said she made it home, but they later said she had not.

Anyone with information on her whereabouts is asked to contact the Conway Police Department in New Hampshire at: (603) 356.5715 or the  National Center for Missing and Exploited Children at: (800) THE LOST (800.843.5678)
