Authorities discovered the Capuchin monkeys in crates, the North Port police said in a statement.
Police identified the woman as Linda Marie Smith, of Arcadia, Florida. She was found Friday at a Budget Inn in North Port.
"There was no obvious signs of trauma to Smith's body," police said. "The cause of death is undetermined at this point. The medical examiner will soon conduct an autopsy," CNN reported.
An incoherent man, who was in the room with her, received medical attention and was undergoing questioning.
The Florida Fish and Wildlife Conservation Commission is taking care of the monkeys.
