Unwilling to wait any longer, James Kim left his wife and two young children in their frozen, snowbound car and set off into the wilderness to seek help, wearing only tennis shoes, a sweater and a jacket. Now he is the one who needs help. A helicopter spotted his wife, Kati Kim, 30, waving an umbrella Monday afternoon. She and her daughters Penelope, 4, and Sabine, 7 months, were airlifted to a hospital and are in good condition. The fate of her husband is unknown. Trained dogs, horse patrols and a helicopter with heat-seeking capability were to join other helicopters, snowmobiles and foot patrols Tuesday for the 35-year-old. Trackers followed his footprints until dark Monday night.
