A dispatcher told ABC15 in Phoenix that four other people have unknown injuries and that authorities are possibly looking for one or two more people.

A helicopter operated by a Boulder City-based tour company crashed Saturday evening in the Grand Canyon, killing three and critically injuring four, according to police. KLAS reports "rugged, windy conditions have made it impossible to get four trauma victims out" per the Hualapai Police Chief.

The survivors were airlifted to a Las Vegas hospital by around 2 a.m. Sunday, Bradley said.

"The ladies were screaming.It was just terrible", he said. Rescue crews had to be flown in, walk to the crash site and use night vision goggles to find their way around, he said.

The crash will be investigated by the National Transportation Safety Board and the Federal Aviation Administration.

The carrier has not commented on the crash at the time of publication.

The company's website said it flies roughly 600,000 passengers a year around the Grand Canyon and on other tours.

The A.P. said a phone call and an email to Papillion were not immediately returned Saturday.
