Fla. teen last seen a month ago still missing

TALLAHASSEE, Fla. -- A month after she disappeared, a 14-year-old Florida girl is still missing, reports the Tallahassee Democrat.

Adelle Burns was last seen Aug. 26 when she went to bed with her younger sister at her family's Tallahassee home, reports the paper. Her mother awoke early the next morning to find the middle school student gone.

She had left a note explaining that she would be with friends in Mississippi, reports the paper. But there's been no word from her since.

The Leon County Sheriff's Office is investigating Burns' disappearance as a runaway case, and they reportedly don't consider her to be at risk. However, spokesman James McQuaig told the paper, "regardless of what her status is, this is a 14-year-old girl that's unaccounted for and that's a huge problem for us. There's a great concern for this child's safety."

The department has served search warrants, issued court orders and subpoenas, administered lie detector tests and analyzed multiple electronic devices in the multi-state investigation, McQuaig told the paper.

Friends and family are offering a $1,000 reward for information, and have used billboards, fliers and social media in an attempt to spread the word.

The girl's mother, Glenna Phillips, told the paper she feels her child should be considered endangered.

"Somebody is helping her. A 14-year-old cannot run away and survive on her own without money or anything. There's so many ifs in this situation," she reportedly said.

Burns is described as five feet, three inches tall with brown hair and brown eyes. She was last seen wearing shorts and a tee shirt. Anyone with information is asked to call the Leon County Sheriff's Office at (850) 606-5800.
