Police pulled the body of a 58-year-old man from the water near Mallory Square Monday morning, but what caused him to reportedly fall in was unknown.
The death did not appear to be a homicide, and there was nothing suspicious reported at the scene, but the investigation is ongoing, said police spokeswoman Alyson Crean.
One 911 caller reportedly saw a man sleeping on the pier at Mallory Square fall into the Key West Channel at 6:56 a.m., according to police dispatch records. A second caller bicycling by and reported seeing the man face-down in the water near the Key West Aquarium, Crean said.
The man's name is being withheld pending notification of next of kin, Crean said.
Based on early reports, it appears the man was not from Key West. It wasn't known how long he had been in town, Crean said.
"We're still unclear on what his living situation was," Crean said.
It appeared the cause of death was drowning, but detectives are awaiting toxicology and autopsy reports.
Firefighters were at the scene early, but did not remove the man because of "obvious signs of death," and assisted police, said Division Chief Mike Davila.
"We did secure the body, but once it was clear he was deceased we waited and assisted police in removing it," Davila said.
The Coast Guard also assisted police marine unit officers remove the body of the man from the water, Crean said.
