What began as the story of a Montana man who committed suicide in Singapore has now turned into an international investigation involving the U.S. government.

Shane Todd, who died last June, was a key player in the use of gallium nitride, rather than silicone, to create a new generation of semiconductors. Shane was working with the Institute of Micro Electronics, but it appears the institute had close ties with Chinese firm Huawei (pronounced "Wah-Way"). Shane's brother Dylan, a student at the University of Montana, says that his brother became uncomfortable with what the company might be doing with the technology.

"He would tell me 'I'm going to make cell phones faster, way faster than they are now," said Dylan, recalling his brother. "I think that's what he really wanted to do, but this technology could also be used for military applications and these microchips could also be used for military weapons. To make them more efficient. I believe that he didn't want that kind of information in the hands of someone who would try to use them for military applications, especially if it was a country that would be using them against our country."

Dylan Todd:

Singapore authorities said that Shane hung himself in a bathroom, but no pictures were taken of the scene. The report given by Singapore authorities says Shane had bolted a pulley to the wall to hang himself.  When the Todd family traveled to Singapore, however, no evidence of bolt marks were found on the walls, which were made of marble.

"My parents have now gone to Washington D.C.. They've met with Senator Baucus, Senator Tester. Also, John Kerry has put a lot of effort into trying to figure out what happened to Shane as well. By no means is this story over. What they didn't realize is what kind of family they were messing with. What they didn't realize was that we were going to the ends of the world to make sure justice is brought upon the people that did this to my brother."

The Todd family found out this week that Singapore authorities have set a court date for May 13. Dylan says his family, along with a team of experts will be in Singapore for the hearings.
