“We have recovered six sets of remains", Kanoho said, as quoted by NBC News.
He added that a search and rescue operation would continue, but there were “no indications of survivors".
The helicopter failed on Thursday to return on time from a sightseeing tour of the island of Kauai with one pilot and six passengers aboard, two of them reportedly minors.
On Friday, the Kauai Police Department said in a statement that the rescue teams had found the wreckage of the helicopter.
