According to the latest report, he was sharing a two- bedroom apartment with three male and female students, and they are all Chinese. There was one female roommate home while he walked back to his apartment. She reported his death on the next day. That 's too sad. He even did not bother to talk to her about the incident, to be helped! The reason I guess that he was quite and introverted. If he got an open and extroverted personality, he could be saved!
