Hurricane Dorian battered the Bahamas earlier this month killing at least 50. The death toll is expected to rise as the clean-up operation continues.
Police Commissioner Anthony Ferguson said that the search for the victims was a slow process.
"We have to go through all of that rubble, take our time and search. It's going to take a long time before you can really say," he said.
