SAN FRANCISCO — Technology, some lucky text messages and an outdoorsman’s intuition helped locate three members of a family stranded in the Oregon backcountry for nine days.
Searchers rescued Kati Kim, 30, of San Francisco and her daughters Penelope, 4, and Sabine, 7 months, along a remote forest road Monday afternoon. The key to finding them, police said, was a “ping” from one of the family’s cell phones that helped narrow down their location.
According to one of two cell phone engineers who honed in on the Kims, the chance of the split-second signal making it through the rugged mountains was “very slim.”
“It was just a hunch that we could help. And we followed up on the hunch,” said Eric Fuqua, 39, an engineer for Edge Wireless LLC who contacted authorities to offer his services in the search. Edge Wireless provides cell phone coverage in southern Oregon, and is a member of Cingular Wireless’ network.
