Victoria had traveled to Tampa, Fla., for the weekend to visit friends, which included a trip to explore the ruins of Fort Dade from the Spanish-American War on July 24, according to group member Victoria Silberbusch.

“What began as a fun, innocent day on the water with both old and new friends ended in an unimaginable and unexpected tragedy,” she shared on Instagram July 26. “Everything changed in a matter of seconds.”

The New Jersey native suffered a “devastating fall” that turned out to be worse than her friends thought.

“At first, we thought Victoria had fallen only one level,” her friend said. “We ran to the edge, calling out to her, but quickly realized she had fallen much farther than we first believed. We immediately began climbing down to reach her while others called 911.”
