June 4 (UPI) -- The family of a 20-year-old American college student who went missing in Japan nearly a week ago is appealing to the public for help in locating him.

The parents of Auburn University student James "Weston" Higginbotham on Thursday spoke to CNN, People Magazine and local media in the Kyoto area in their quest to find their son, who disappeared during a family trip.

Weston's mother Nancy Higginbotham said in a Facebook update that she had conducted 10 media interviews during what she called "a long, stressful day."

"Today, dozens of Japanese police officers searched through waist-high mud in an effort to find Weston," she wrote. "Search dogs and helicopters were also deployed. We had to wait in the apartment during the search.
