Police say they have new clues in their search for a San Francisco family who went missing a week ago during a vacation in Oregon.

James and Kati Kim and their two young children stopped to see friends in Portland a week ago on their way home. They got back on the road to head to Gold Beach, in southern Oregon where they would stay overnight. But the family never arrived.

The Douglas County Sheriff's Office said Saturday a search of the family's credit card history showed they had stopped for dinner last Saturday night in Roseburg, about 160 miles south of Portland and 65 miles northeast of Gold Beach.

"We don't have any indication of foul play," Sgt. Roger Loomis of the Douglas County Sheriff's Office told KATU-TV. "They were in Roseburg, they had dinner and they left and that's about the only information we have right now."

Also, a citizen said Saturday morning that they saw the family's vehicle in the same area as the restaurant, according to the sheriff's office.

Searchers have been combing Oregon highways and surrounding areas to look for signs of the family. Searchers have also used snow machines, poking into byways along Oregon's Coast Range.

Helicopters, including one commissioned by the Kims' family, have also been used in the search.

The couple has two children, Penelope, 4, and Sabine, 7 months.

Anyone with information on the Kim family is asked to call 911, or the Oregon State Police Northern Command Center dispatch at (800) 452-7888, or the San Francisco Police Department Missing Persons Unit, (415) 558-5508.
