Chinese National Named VTech Massacre Killer

Update: 11:45 p.m. (Revised)
The gunman apparently brought the chains used to lock doors in Norris Hall on campus with him. He was a 20-something, six foot tall, Chinese man toting a 9mm handgun with at least one high capacity clip, along with a .22 caliber pistol. It is also now known that the shooter brought additional ammunition with him -- as noted by multiple student witnesses.
At least two people (Chief Flinchum and a Sun Times reporter) now say they have the name of this person, but will not yet release it to the public. The man, who was reportedly NOT a VTech student, was in the US on an F1 visa (aka student visa).
Federal authorities are saying that they still cannot definitively tie the West AJ murders to the Norris Hall massacre. I'm starting to believe, more and more, that the two scenes are unrelated. However, the facts are easy enough to establish. a) Did the murdered girl in West AJ know the Chinese man at Norris Hall? b) Who did witnesses see in the dorm? c) Who is the person of interest the Blacksburg police talked to this morning? d) Can he be quickly linked to either the Chinese gunman at Norris or the young woman at West Ambler Johnston?

FOX News is reporting that the Chinese man has a page on Facebook.com. On his profile, there are pictures of him holding several weapons. We are NOT sure the Facebook.com person is the SAME PERSON who massacred 30+ people today. However, if the profile does show the shooter, the situation is even more disturbing.
