A plane crash near the remote western Alaska village of Saint Marys killed four of the 10 people aboard, including an infant boy, an Alaska State Troopers spokeswoman said Saturday.

The pilot and three passengers died in the Friday night crash, spokeswoman Megan Peters said.

Peters had no immediate word on the six survivors' condition.

The single-engine, turboprop Cessna 208 was a Hageland Aviation flight from Bethel to Mountain Village and Saint Marys, said Kathy Roser, a spokeswoman for Era Alaska airline. Hageland is part of Era Alaska, Roser said.

The wreckage was found about 4 miles (6kms) east of Saint Marys.

An emergency locator beacon signal helped pinpoint the crash site, National Transportation Safety Board investigator Clint Johnson said.

There was no immediate word on what might have caused the crash. The NTSB planned to send two investigators to the scene Saturday.

The temperature in the area Friday night was about 18 degrees (-8 Celsius).
