North Carolina authorities said Monday that a letter was found with the body of an Appalachian State University student who had been missing for more than a week, WJHL.com reported.

The body of Anna M. Smith, 18, was discovered in a "heavily wooded area" near the university's Boone campus. Police said the remains were found Saturday morning in a wooded area at the west end of town.

"At this point we do not have direct information that there is foul play," a Boone police statement said. "In fact, there are factors to indicate that Ms. Smith was intent on harming herself. I know this is difficult for family and friends to hear, but these are facts."

Police did not discuss the contents of the letter, but said it will be analyzed. An autopsy is scheduled.

Authorities, family and friends had been searching for the High Point teen since she left her college dorm and disappeared on September 3. Hundreds of mourners came out to an open field Sunday night to show support for Smith's family.

The Sunflower, which Smith had tattooed on her chest, became a symbol of remembrance and mourners say Anna was an angel that was taken from them too soon.
