It's been seven months since a New Hampshire teenager vanished last fall on her way home from high school, and her mother is offering a $10,000 reward for information leading to her safe return.

Fifteen-year-old Abigail Hernandez was last seen Oct. 9 after leaving Kennett High School in Conway. Police say she walked her normal route toward home and sent several texts between 2:30 p.m. and 3 p.m. But she never made it home.

Hernandez is described as a white girl of Hispanic ancestry who is 5-feet, 4-inches tall and weighing approximately 118 pounds. She has with brown hair, brown eyes and light olive complexion.

Abigail's mother, Zenya Hernandez, said somebody knows what happened to her daughter and asked them to come forward with any tips or information, even if it's simply about somebody's change in behavior after Abigail's disappearance.

Anyone with information is asked to call either the Conway Police Department's tip line at 603-356-5717 or the FBI at 1-800-CALL-FBI.
