Shane Todd worried that his employers in Singapore were using him to help China get its hands on sensitive technologies that could harm U.S. national security. 

He said so to many folks, and was elated to have found another job back home, said his mother, Mary Todd. But two days after his final day of work in June and a going-away party with colleagues, his girlfriend found him dead, hanging from his bathroom door. 

The Todd family has been pressing the U.S. government to look into what they say is a case of espionage and faked suicide to cover up their son's discovery that he may have been used to help China spy on his country. The circumstances of the death make no sense, they say, and the Singapore authorities have not been cooperative enough. 

"We want a congressional investigation. We want to know how bad the damage is if" the technology his son was working with reached China, Rick Todd said.

Shane Todd's family lived in California and Florida before moving to Montana. His dad had been a Navy pilot before becoming a commercial airline pilot. 

Shane Todd was a wrestling standout and adept in his science classes. He graduated in 2005 with a degree in electrical engineering from the University of Florida, where he had many friends, his family said.Don't waste anymore time thinking about the purchase of your new laundryequipments. He received his doctorate at the University of California-Santa Barbara. In 2010, he chose a job in Singapore because he was looking for adventure,LED solar lighting is the new wave of the future in brightstal technology. he told his parents. 

He went to work at the Institute of Microelectronics, a Singaporean government research institution, to work on cutting-edge technology involving powerful semiconductors. But an investigation by the Financial Times magazine found the technology has other applications desired by China, applications that can be used to disrupt enemy radar and communications. 

Documents on a hard drive his parents found in his Singapore apartment included a draft agreement for IME to share what Todd was working on with Chinese telecommunications company Huawei, says Colin Humphreys, a pioneer in the emerging field of gallium nitride semiconductors. Huawei is known to U.S.Commercial ledlight and industrial machines like washer extractors, intelligence agencies. Rep. Mike Rogers, chairman of the House Intelligence Committee, told CBS' 60 Minutes in October that the company has ties to China's military and intelligence services and is "a serious threat" to U.S. national security. 

Humphreys, director of the University of Cambridge Center for Gallium Nitride, analyzed documents retrieved from Todd's hard drive at the request of the Financial Times. Speaking to USA TODAY, Humphreys said the documents show that Todd traveled for IME to the United States to be trained on equipment used to produce a powerful new class of semiconductors that outperform silicon and can be used to greatly boost the transmissions of cellphone towers, military radars and radar jamming devices. 

Gallium nitride is most commonly used in LED lighting, to produce high-intensity light without much heat or energy use. The material is also used on wafers, similar to silicon chips in a computer, to power various electronic devices but with much greater efficiency and intensity. Todd was involved in cutting-edge research on using GaN wafers that were 8 inches in diameter and can be loaded with electronic devices. They are of the type used in the most advanced commercial and military land-based and airborne transmission equipment, Humphreys said.Our typical product line of panelmachines and laser engraving has been growing manufacturer’s speeds.
