Sirius Black ~ Dead or Alive?

Question:

Sirius Black ~ Dead or Alive?

Previously in the book they say green bolt is the killing curse and red is stunning. And before Bellatrix Lestrange actuall hit Sirius it said a red bolt. SO, if Sirius did only get stunned then he is not dead. But do you die if you fall through the veil?

What are your thoughts and Why do you think that?

Best Answer - Chosen by Asker: Since Luna and Harry heard voices coming from behind the veil it is possible that Sirius is still alive. Whether or not he can come back through the veil or communicate with Harry somehow (with the two way mirrors perhaps?) now that is something I hope JKR explains in book 7.
