Aan had been shot more than 100 times by an air rifle. The pellets that struck her face caused her blindness. Last year, Aan was given a special surgery to see if her sight would return, but her optic nerve was too damaged for her to ever see well enough to survive in the wild on her own.
"We knew it was a possibility, but we were hoping it wasn’t the case,” Claudia Hartley, the surgeon who tried to save Aan's sight, said. “Emotionally, it was hard. It would have been a dream to release her.”
