The search for a missing boater was called off Monday evening, nearly 24 hours after a young woman was reported missing in the waters of Biscayne Bay.
Police have questioned the man and woman who were also on board the boat.
Investigators are calling the disappearance of 26-year-old Lauren Jenee Lamar unusual and they are not ruling anything out.
Coast Guard crews and police spent Monday searching a three mile stretch of Biscayne Bay for Lamar, who has been missing since 11 p.m. Sunday.
"Even when you have clear waters it's a needle in a haystack and it's a big haystack," said Jorge Pino of the Florida Fish and Wildlife Conservation Commission.
Police say the driver of the boat, Russell Bruce pulled up to the dock Sunday night with another woman, Alicia Bartolota, and then noticed Jamar was not on board.
He told police he thought she was sleeping in the small cabin inside the thirty foot vessel.

"I don't know if I've ever heard of someone falling off a boat, especially when there's only three people on board and the two people that are left on board not realize that that happened," Pino said.
Police say the three friends were partying at Stiltsville and cruising back to Matheson Hammock Park Marina when Lamar disappeared. No one on board was wearing a life vest.
Fellow boat captains at the marina were shocked by the news.
"Absolute morons. How do you not accommodate for all of your people?" asked Scott Snay
Lamar is an event promoter in Miami. She moved to South Florida from Jacksonville late last year. NBC 6 reporter Dan Krauth spoke by phone with her boss, Nick Field of World Crawl.
"This is obviously a huge shock and my first reaction is just to get as much information as possible and to keep looking for her because I'm just trying to stay optimistic and make sure she's okay," Field said.
The last tweet Jamar sent out was Saturday night saying, "God will either give you what you ask for or something far better."
A day after her disappearance investigators are still calling the operation a "search and rescue mission."
"She's a very motivated person, loves smiling, loves to dance. She's very business minded, a hard worker and she brightens up a room anytime she walks into it," Field said.
The search and rescue operation will continue Tuesday.
