Four people were killed -- including an infant -- and six injured after a small commercial flight crashed Friday near a remote village in western Alaska, police said. 

After failing to revive her newborn, the mother then walked nearly a mile to seek help, police said.

The pilot and three passengers died in the Friday night crash near the village of St. Marys, Megan Peters, a spokeswoman for the Alaska State Troopers, said Saturday.

The dead were identified as pilot Terry Hansen, Rose Polty and Richard Polty and the infant, Wyatt Coffee.

Peters said she 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.

Jim Hickerson, president of Hageland Aviation, told the Anchorage Daily News the six survivors were injured.

The wreckage was found about 4 miles east of Saint Marys. Troopers and an air ambulance service responded to the scene, Peters said.

The survivors are Melanie Coffee, Pauline Johnson, Kylan Johnson, Tonya Lawrence, Garrett Moses and Shannon Lawrence.

Coffee unsuccessfully tried to revive her newborn baby and then walked nearly a mile to lead searchers to the wreckage site.

Village Police Officer Fred Lamont Jr. said Saint Marys responders received word of the crash when Coffee of Mountain Village called a village health aide seeking help in resuscitating her newborn.

Lamont says Coffee considered starting a fire to attract searchers but finally just walked to lights near the community landfill, where she met searchers.

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 caused the crash. The NTSB told NBC News that it would send two investigators to investigate the accident.

The temperature in the area Friday night was about 18 degrees.

Saint Marys, with a population of about 500, is roughly 470 miles from Anchorage.
