COPELAND (CBS4) – A 90-year old southwest Florida woman remains hospitalized after she lost her leg in an alligator attack.

Florida wildlife officials said Margaret Webb was walking near her home in Copeland, a small community east of Ft. Myers, on Wednesday when an 8-foot alligator lunged out of a canal. The gator clamped onto Webb’s leg and tried to drag her into the water.

Webb, however, was able to hang on long enough for a man driving by to stop and help her. That good Samaritan tried to shoot the alligator but it got away.

Wildlife officials at the time said the leg was “barely attached” after the attack and had to amputated.
