Police: Missing foreign exchange student found safe inside tent in Utah in 'cyber kidnapping'

Tonight, police in Riverdale, Utah say they found 17-year-old Kai Zhuang in a snowy camping area about an hour outside Salt Lake City where temperatures dropped to freezing at night. Police say what happened to Zhuang is part of a disturbing criminal trend called cyber kidnapping and that kidnappers threaten young foreign exchange students and their families and they demand ransom. Victims are told to isolate themselves and then closely watch through FaceTime calls and or Skype. They're told to send photos of themselves to cyber kidnappers under duress, which are then sent to the parents, making it seem like they're held captive. The victims are told their families will be harmed if they don't comply. Police say Zhuang's parents in China alerted them that he had been kidnapped, leading police to discover that he had bought camping gear. They say after analyzing and assessing bank records, purchases over the last month, cell phone ping records and the camping incident, they were able to pinpoint where he might have isolated himself. They found him in the Brigham City Canyon area with very little heat and food, but with several phones that were presumed to be used to carry out the cyber kidnapping and that Zhuang only asked to speak with his family and a warm cheeseburger. Police are warning families, especially foreign exchange students, that if you think you're a target of cyber kidnapping, call your local police department. Do not send money and stop talking to the people who are calling you. Zorin Shah, ABC News, Los Angeles.
