25 year-old Sun Danyong commited suicide after a fourth-genenation iPhone-prototype under his care went missing. He was responsible for handling and sending prototype iPhones to Apple. It seems that one of sixteen iphones went missing and when he couldn’t find it, he commited suicide. Reports coming in from China speak of a threatening situation leading to his suicide.

On Thursday, July 9th, Sun got 16 prototype phones from the assembly line at a local Foxconn factory. At some point in the next few days, he discovered that one of the phones was missing. He suspected that it had been left at the factory, but couldn’t find it. On Monday, July 13, he reported the missing phone to his boss. Then, that Wednesday, three Foxconn employees searched his apartment — illegally, according to Chinese law. Accusations are flying that Sun was detained and physically abused during the investigation, although this has not been substantiated (possible evidence: there’s this somewhat garbled and potentially faked instant message exchange from Sun shortly before his death)
