ST. LUCIE COUNTY — Layne Chesney has died, more than 16 months after being severely burned.

"I'm just proud to have been her mom," Leigh Ann Wirz Chesney said. "I hope she will give me the strength to learn how to live without her."

Layne died Friday morning from organ failure, Wirz Chesney said. She said the 16-year-old died peacefully with her mother, grandmother, nurses and a few doctors by her side.

"Her organs were just too weak," she said. "Her wounds were not ever closed despite being hospitalized for a year in Miami."

Fighting every single day

On New Year's Eve 2017, 14-year-old Layne threw gasoline on a bonfire and received severe burns over 95% of her body.

Doctors originally told the Chesneys that Layne had a slim chance of surviving more than a day after the incident. The teen fought through over 80 surgeries and numerous skin grafts.

After Layne survived 24 hours, doctors told the family her chances were still small, but they would keep pressing to keep the teen alive on a day-by-day basis.

"I'm just proud of her for fighting every single day," Wirz Chesney said.

For about the first year after the fire, Layne was being treated at Kendall Regional Medical Center in Miami.

"We started to notice a decline in Layne (at Kendall Regional Medical Center in Miami)," Wirz Chesney said. "We noticed emotionally, she wasn't doing very well and she really wasn't progressing as fast as we would like."

On Jan. 18, Layne was transferred to Shriners Hospitals for Children in Galveston, Texas, which specializes in burn patients, for more extensive treatment.

Throughout her time at both hospitals, Wirz Chesney said the teen received cards and motivation from people across the country with similar burn stories or words of encouragement.

"I'm very, very, very grateful for all the prayers and cards that people send me," Layne said in December. "I don't know any of them, but they still send me cards and encourage me and they keep me going."

Layne's mother said the teen never gave up or stopped fighting, but that her organs failed after the girl continued to fight off constant infections and numerous failed surgeries.

"She deserves to be honored," Wirz Chesney said. "Half of my heart is gone forever."

According to a May 8 post by her mother to Facebook in a group she created 'Pray for Layne Chesney', the teen was having trouble with oxygen saturation levels, her urine output had decreased and her heart wasn't functioning as well as doctors would have liked.

"Please continue praying for us all," the post said. "I wish I had more positive things to post about, but we continue to be in a rough patch."
