(CNN) – A University of West Georgia graduate psychology student is fighting for her life with a flesh-eating bacteria after falling off a homemade zip line and cutting her leg, CNN affiliate WSB reports. Aimee Copeland, 24, fell off a homemade zip line near a friend's home in Carroll County, Georgia, on May 1. Doctors at a hospital in Augusta were forced to amputate most of her right leg on Friday after the bacteria destroyed her leg muscles and moved into other parts of her body. She stopped breathing and one point and had to be resuscitated, her father, Andy Copeland, told WSB. “It's a miracle she made it past Friday night,” Andy Copeland said. The Atlanta Journal-Constitution reports that Copeland contracted Aeromonas hydrophila in the deep gash in her leg after the zip line broke. The paper says Copeland is in critical condition at a hospital in Augusta and is at risk of losing more limbs. Her father says doctors have told her family that her chance of survival is “slim to none.”
