Henry Kacprzyk, curator of reptiles at the Pittsburgh Zoo and PPG Aquarium, said the alligator spotted during the fall at the Beaver Run Reservoir in Westmoreland County may not have died during the winter, as officials in the county were expecting, the Pittsburgh Tribune-Review reported Monday.
"This is the mildest winter I can remember," Kacprzyk said. "In order for it to die, you would have to have some sustained cold weather. I would say there's a possibility it survived."
Gina Cerilli, spokeswoman for the Municipal Authority of Westmoreland County, said there have not yet been any sightings of the creature -- dead or alive.
"We always have security looking over our property," she said. "None of our employees have seen the alligator."
