Searchers intensified their efforts Tuesday to find a San Francisco man missing for more than a week in a rugged, remote area of the snow-covered Oregon Coast Range as his wife and two young children, rescued just the day before, recovered in a hospital.

Trained dogs, horse patrols and a helicopter with heat-sensitive sensors were sent to join other helicopters, snowmobiles and foot patrols Tuesday for 35-year-old James Kim. Trackers had followed his footprints until dark Monday night.
