Cell Phone 'Ping' Key To Finding Family

Technology, some lucky text messages and an outdoorsman's intuition helped locate three members of a family stranded in the Oregon back-country 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.

Meanwhile, fresh search teams prepared to join the hunt for James Kim, 35, who set out on foot Saturday to find help for his stranded family in Oregon's snowy coastal mountains.

Searchers were led to the area where James Kim walked away from the family car by lucky bit of technology, reports CBS News correspondent John Blackstone. Though cell phone signals are rare in the area, the family's phone connected briefly to a distant tower as it received a text message. That gave searchers a place to look.

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.

Fuqua and co-worker Noah Pugsley started digging through computer records of cell phone traffic Saturday and learned that one of the Kims' cell phones had received two text messages around 1:30 a.m. on Nov. 26, the day after the family was last seen at a restaurant in Roseburg, Ore.

The engineers were able to trace a "ping" from the Kims' phone when it received the text messages. They located not only the cell tower in Glendale, Ore., from which the messages were relayed, but a specific area west of the town where the phone received them.

With the family's possible location narrowed down, the pair used computer software to create a map predicting what parts of the mountainous region received any cell phone coverage at all.

Fuqua then relied on his extensive experience traveling the heavily forested back roads as both a fisherman and a technician, he said, to guess the course the family may have taken as they headed from the mountains toward the coast.

The engineers' sleuthing led searchers to focus on Bear Camp Road.

The rescued members of the Kim family were found with their snowbound car just off that road, which Fuqua called "impossible" terrain to navigate for anyone with no knowledge of the area.

The complicated network of roads in the area is commonly used by whitewater rafters on the Rogue River or as summer shortcuts to Gold Beach — the Kims' destination when they went missing. The roads are not plowed in winter.

Searchers were lucky that the Kims received a cell phone signal at all in an area with "very, very sparse coverage," Fuqua said. "Every now and then, if you go slow enough, you'll hit our towers for just one second in that one spot," he said.

Details of the contents of the text messages and who sent them have not been released.

But law enforcement officials said the engineers' analysis of the messages was the critical breakthrough that searchers needed to ultimately spot three of the Kims by helicopter as Kati Kim waved an umbrella marked "SOS."

"From what I understand about (Fuqua's) help in this case, as far as I'm concerned he's a hero to me," said Inspector Angela Martin, who led the San Francisco police's investigation into the Kim's disappearance.

The focus of the search for James Kim now is a steep and rocky river valley.

Bob Harrison was part of an overnight search team.

"It was very rough going, very slow, we didn't go near as far as we hoped we could," Harrison told Blackstone.

Late Tuesday, they found a pair of gray pants that may have belonged to Kim. His family said he was wearing them over a pair of jeans.

"It could be he was leaving markers that if people were searching for him, something to follow. The way we're treating it, it gives us an indication we are in the right area," Josephine County Undersheriff Brian Anderson said.

"This is frustrating. We are so close," Anderson said Tuesday evening. "There are people pouring their heart and soul into this. We are not going to quit until we find him."

Kim went about two miles along the road then headed down into a drainage area, said Lt. Gregg Hastings of the Oregon State Police. The pants were found about a mile from where Kim left the road.

"It could be a sign he's trying to indicate the path he was going," Hastings said.

It also could mean Kim suffered severe hypothermia, said Dr. Jon Jui, professor of emergency medicine at Oregon Health and Science University. Jui said severe hypothermia causes people to become disoriented and have a false sense of warmth, which can lead to them disrobing.

"This is a bad sign," he said.

Anderson said searchers are trying to recover another item he did not identify that might belong to Kim.

The rescue of Kati Kim and her daughters showed searchers that miracles can happen, notes Blackstone. Now they're hoping for another miracle.
