the father James Jin walked 47 km from the montain to get help for his wife and 2 kids in the car stuck in the mountain road which should have been closed in winter but did not that year. he was dead, and his family rescued by the research team after 1 week. Because the coworker reported he didn't come back for work and some body report a 1 second 911 call from the mountain area. sad sad story, couldn't sleep after reading it.
