LARGO, Fla. (WFLA) — Pinellas County deputies and the Florida Fish and Wildlife Conservation Commission were investigating a death on Friday that involved an alligator, officials said.

The gator was 13 feet, 8.5 inches long, according to the sheriff’s office. It was “humanely killed” by deputies and removed from the waterway. The body of an adult was also pulled from the waterway.

The Pinellas County Sheriff’s Office said that at about 1:50 p.m., deputies were sent to the area of 134th Avenue North and 121st Street after learning of a deceased individual in the area.

A representative with the sheriff’s office confirmed that the incident involved an alligator.

“This was the first big one that I’ve seen around here,” said Jennifer Dean, who has lived in the area for four years. “We heard all the sirens and came out to see what was going on.”

The FWC has also been called in to assist local law enforcement.

“The FWC is currently assisting PCSO with an ongoing incident involving an alligator,” an FWC statement said. “We are still gathering information at this time. I will share more when it becomes available.”

“It’s crazy,” Dean said. “My kids walk by there all the time, so it’s really scary.”

An autopsy will be conducted to determine the man’s cause of death, officials said.
