What began as a quiet walk with her beloved dog ended in an unthinkable tragedy for 85-year-old Gloria Serge.

Serge was walking her Shih Tzu, Trooper, near a pond at the Spanish Lakes Fairways retirement community in Fort Pierce, Florida, in February 2023 when a massive alligator suddenly lunged from the water.

The nearly 11-foot reptile appeared to go after the small dog, but instead clamped onto Serge’s ankle and dragged her into the pond as her terrified neighbor watched helplessly from nearby.

Carol Thomas, who lived in the same 55-and-older community, said she heard a commotion and looked outside to see Serge on the ground while Trooper ran up the hill.

“I saw the alligator come out and grab her leg,” Thomas recalled.

In the frantic moments that followed, Thomas tried desperately to help her neighbor. She urged Serge to swim toward an overturned paddle boat in the lake, hoping she could push it toward her and give her something to grab onto.

But Serge could not get away.

According to Thomas, Serge surfaced briefly and called out that she couldn’t swim because the alligator still had her.

Thomas then grabbed a metal pole and planned to strike the gator in the snout, but the animal pulled Serge under before she could reach her.

“There’s nothing you can do,” Thomas later said, describing the haunting helplessness of watching the attack unfold. “I don’t know what else I could’ve done.”

Trooper escaped unharmed.

Officials later confirmed the alligator responsible for the deadly attack was captured and euthanized. The Florida Fish and Wildlife Conservation Commission said Serge had been walking her dog along a retention pond when the alligator attacked.

The tragedy devastated Serge’s family, who later spoke publicly about the horror of her final moments.

“I never could have imagined the agonizing way that my mother spent the last moments of her life,” her son said, describing the attack as sudden, violent and impossible to process.

The Spanish Lakes Fairways community spans hundreds of acres and includes multiple bodies of water where alligators had reportedly been seen by residents.

Wildlife experts have warned Floridians and visitors to keep a safe distance from alligators, especially near ponds, canals and lakes. Small pets can draw the attention of gators, and officials have repeatedly urged people not to feed, approach or attempt to interact with the reptiles.

Amy Kight, executive director of Busch Wildlife Sanctuary in Jupiter, warned that people should not try to treat alligators like harmless neighborhood wildlife.

“Do not feed them, do not mess with them, do not try to befriend them,” Kight said. “Let them live their life, you do yours and you shouldn’t run into any problems.”

Serge’s death remains one of Florida’s most disturbing recent alligator attacks — an ordinary afternoon walk that turned deadly in seconds, leaving a neighbor haunted and a family shattered.
