Divers have found the body of a woman dragged into a lake by an alligator while walking her dogs.
Fatal attacks on humans remain rare, however.
One had a fresh wound on its side, they noticed, so they alerted authorities.
It urged people to "exercise caution with our families and pets, mindful that alligators, snakes, and other wildlife may be in the area".
"[Matsuki's] dogs won't leave the pond", Davie Police Maj.
"A 12-foot, 6-inch alligator was removed from the lake by an FWC-contracted trapper".
The Fish and Wildlife Conservation Commission said that the park is city owned and signage is its responsibility. Broward County Animal Control and Adoption Agency said that they had taken custody of the dogs.
A man told detectives that he saw Matsuki walking her dogs in the park.
Matsuki's body was recovered from the lake that night. The witness told police the woman was gone the next time she looked, but the dogs were still there, the TV station said.
"We would like to extend our heartfelt condolences to the family and friends of Ms. Matsuki", conservation commission spokesman Rob Klepper said in a statement.
"She probably thought that Lake was [a] safer alternative, after so many gators have been showing up around here lately".
The warning from the neighborhood association about alligators in the water may have prompted her to change things up and go to a lake farther away.
The likelihood of a Florida resident being seriously injured during an unprovoked alligator incident in the state is only 1 in 3.2 million, according to the wildlife commission.
A 2-year-old boy was killed by an alligator at Disney's Grand Floridian Resort & Spa in 2016.
