Sue Fortenbery from St. Petersburg told InsideEdition.com that she and her 18-year-old grandson, Kevin, were taking a walk at Joe's Creek Greenwood Park when suddenly, their dog Bolt took off after a rabbit.

The Jack Russell Terrier followed the rabbit under a hole in the fence, where Fortenbery said, "a gator was laying on the bank waiting for him."

Then Fortenbery said she heard two screams--one from her grandson, followed closely by a scream from her dog.

Moments later, little Bolt was dead.

"I knew there was a gator out there, but I didn't know it came to the bank like that," the devastated grandmother said. "What a way to find out, huh?"

Even though Fortenbery said she has been frequenting the park several times a week for the past year, "I just don't think it's safe anymore," she said.

She reported the incident to the park ranger, who said the only thing they would be able to do is to keep an eye out for future incidents.

"That's the stupidest thing I've heard in my life," she said.

Fortenbery is now pleading with the park to fix holes at the bottom of the fence, and remove the alligator.

"There are people out there walking dogs, pushing strollers with little kids," she said.

InsideEdition.com reached out to Pinellas County park rangers and Florida Fish and Wildlife Conservation Commission, but initial calls were not returned.

"I am thankful Kevin didn't go in the water," Fortenbery said, "or he wouldn't be here either."
