Witness says gator attack was 'traumatic'

"I was walking my dog and all the sudden I looked back and I see this lady kinda falling by the lake a little bit and apparently she was walking her dog close to the edge of the lake," Gene Vance said. "It looked like the gator tried to get the dog but she grabbed the dog really quick, but in turn she slipped down and the gator got her leg just underneath the knee? It was like one chomp and then he went back into the water."
