CONWAY, N.H. (MyFoxBoston.com) -- Investigators believe a missing New Hampshire teen sent her mother a letter two weeks after she disappeared.
During a press conference Friday, officials said they believe Abigail Hernandez wrote a letter postmarked on Oct. 23 that was received by her mother on Nov. 6. There was a delay in receiving the letter because it was sent to a P.O. box that is not checked daily.
State officials said they did not release the details of the letter until December because they had to take every step to confirm the letter's authenticity.
An FBI agent said the letter gave investigators hope because it is unprecedented in other cases. Authorities will not reveal the contents of the letter or where it was postmarked because it could compromise the investigation.
Hernandez has not contacted her loved ones since writing the letter. They hope she will reach out again.
The FBI believes Hernandez could have left Conway willingly on Oct. 9, but she could now be victimized.
FBI agent Kieran Ramsey said, "Other cases that we've investigated across the country tell us that one in eight of endangered runaways could be forced into some kind of sexual exploitation after a situation like this has occurred."
Officials noted the teen has no source of income. They expressed great fear for her safety.
Hernandez was last seen leaving Kennett High School at about 2:30 p.m. on Oct 9.
