An alligator that attacked and killed an 83-year-old woman in southeast Georgia has been trapped and removed from Skidaway Island, officials said Wednesday.

An autopsy performed Tuesday confirmed that Gwen Williams died as a result of an alligator attack. Her body was found Saturday floating in a lagoon.

A biologist for the Georgia Department of Natural Resources says it was the first time an alligator killed a person in Georgia since 1980.

After the autopsy report confirmed her cause of death, a trapper, Jack Douglas, was sent to begin searching for the alligator. He located the 8-foot carnivore in the same lagoon that the attack occurred.

The trapper summoned The Georgia Department of Natural Resources along with detectives from the Savannah-Chatham Metropolitan Police Department to the scene. After capturing the gator, he conducted a necropsy. Authorities said the animal?s stomach contents confirmed it as the gator that caused Williams? death.

A couple riding in a golf cart Saturday spotted Williams' body, which was missing its left arm, right hand and right foot. Police determined she had been dead since Friday evening.

Williams was found about 500 feet from the home she was house-sitting for relatives on Skidaway Island in east Savannah. Williams was from Canada.
