ANCHORAGE, Alaska (AP) - Authorities say three people are feared dead after an Alaska State Trooper helicopter crashed.

Trooper spokesman Megan Peters says the aircraft was carrying a state trooper, a pilot for the troopers and a rescued snowmobiler when it went down on Saturday night.

She says the crash site was spotted on Sunday, and no survivors have been found. She says that though the three are feared dead, their deaths haven't been confirmed.

Wreckage of the helicopter burned, but Ms Peters said it was not known how the fire started or how long it lasted.
