Where's the phone? - Submitted by Chen Yunlin from Beijing, China.

Dear Ralph Hilliard:

I think it's a good idea for you to publish the positive stories about polygraph on the internet. I don't understand why some people distrust the polygraph. I have a real story about some soldiers who were involved in a theft. They were reluctant to participate in a polygraph examination at first, but when the thief was discovered through the use of the polygraph, they understood that the polygraph was a way to clear them of suspicion.

About three years ago, a military unit informed me that a mobile phone had been stolen from an officer. According to the report given to me, the officer had discovered that his phone was missing after returning from a visit to the bathroom. He was sure the phone had been there previously because its ring had awakened him that morning. As he prepared to depart for his office, he discovered the theft. Based upon his statement, there were six soldiers around the dormitory and all would have had access to the phone. The phone itself was unimportant, but it contained telephone numbers that were classified as secret. As a result of testing the suspect soldiers, one clearly showed deception, but refused to confess to the theft. I decided to use a concealed information test in an effort to find the telephone. After running a series of test charts, it became obvious that the suspect was reacting strongly to one of the locations on the test. I suggested the investigating officers to check the hot water room and as I expected, the phone was found hidden in a box in that location. Faced with the discovery of the phone, the soldier confessed to the theft. Through my many uses of the polygraph, I have found that it's most powerful use is not only to determine deception in a suspect, but to also find the evidence.
