Teams combing the wreckage of a Hawaii sightseeing helicopter that crashed on Kauai island found no sign of survivors on Friday and recovered six sets of human remains before suspending the search due to bad weather, police and fire officials said, Reuters reported.

The grim announcement came in a news conference almost 24 hours after the aircraft went down in a remote area of rugged terrain near the end of a tour flight over the island’s famed Na Pali Coast.

The confirmed manifest of the ill-fated aircraft, flown by Kauai-based tour operator Safari Helicopters, consisted of six passengers, two of them children, and one pilot, Kauai County fire battalion chief Solomon Kanoho told reporters.

The identities of the dead were being kept confidential until next of kin could be notified, authorities said.

While the cause of the crash has yet to be determined, Kanoho said the area where the helicopter went down had experienced “some very bad weather” beforehand.
