They also migrate across land. My neighbor found one on her doorstep.When hunting for food, gators are opportunistic hunters. Most likely attacked and grabbed the dog who wriggled away and then
grabbed the woman. Large gators, over 9 ft. or so, wouldn't hesitate to attack a human.
Actually, considering there's more than a million gators in Fl. and
they reside in every county, it's noteworthy that there's not more
attacks than there are. also considering all the lakes and canals
are where they inhabit, attacks are pretty rare.
Have no clue where it came from.
