Authorities say they are investigating the death of Hannah Truelove as a homicide.

Sgt Kiley Sargent with the Hall County Sheriff's Department told The Times of Gainesville that Truelove received injuries that "were indicative that she died from a violent death."

No other details were released.

Truelove's body was found on Friday night. Sargent told the newspaper that authorities don't believe it was a random assault and have information that Truelove may have known her attacker.

Detectives are going through dozens of tips they have received about the schoolgirl to try to determine exactly what happened to her. They are encouraging anyone who might have information about Truelove to come forward.

The teenager's body was discovered in the woods behind the Lake Lanier Club Apartments, where she lived with her mother.

On August 12, she posted: "I got me an uglyass stalker'" and followed it up with a tweet which read, "This can't be happening…"

The following week, on August 18, she wrote: "So scared right now."

Fours days later, the day before she was reported missing, she tweeted: "I need to move out of these dang apartments."

On Friday night, a grandfather visiting his grandchildren found Truelove's body as he walked through the woods.

An autopsy was performed on Monday, which may lead authorities to rule Truelove's death as a homicide.

Sgt Stephen Wilbanks of the Hall County Sheriff's Office told WXIA-TV that it did not appear that Truelove was the victim of a stranger.

As investigators continued to follow every tip today, grief counsellors attended Gainesville High School, where Truelove was a student.

"She had a huge heart. She always put people before herself," friend Joshua Morrow told Fox News.
