(Portland, OR)  --  A Portland State University student who spent months in a coma after being found unconscious near some train tracks under suspicious circumstances says he didn't attempt suicide.  Aaron Salazar spoke out late last month in a video posted to his family's Facebook page.  Salazar says he still has no memory of what happened but that he would never try to take his own life.  Salazar was travelling to Colorado aboard an Amtrak train from Portland last May when he was found unconscious along the tracks in California.  Amtrak claimed that he jumped off the train, but Salazar says that's not true.  KATU reports Salazar's family believes he was beaten and then pushed off the train for being gay.
