I used to work in the Residence Life/Housing office of a university and I can assure you if a resident discussed this type of situation with the RA, more would have been done that it appears was done here. The RA, in this type of situation, should have gone to see their supervisor immediately (and it appears he/she may have). At a large university, you have the RA (just a student themself), a GA (Graduate Assistant..grad student) and a RLC (Residence Life Coordinator...Masters Level Professional), then more people up the chain.
We approved many "emergency" room changes (some to a private room) to ensure a students privacy and safety for much less than this. I can't believe that Tyler was told that a room change could not be approved until a week later. With that said, the other student/roommate would have been called in and had a disciplinary meeting. Sometimes both roommates would have been called in for mediation, but not for this type of incident. However, anonymous reports could be made to the Student Conduct Office of any violations of Housing and/or University rules and regulations.
My opinion, if Tyler went to his RA and IF it was handled appropriately, then the idiot roommate should have been removed from the room, or removed from housing (forfeiting his room costs). At least I believe this is what our director would have done. We had a large LGBT Association on campus and this type of incident would not have gone over very well.
I have a friend who works in Housing at Rutgers. I have emailed them to find out what the atmosphere is like in campus housing. I can only imagine that the Residence Life staff will be having some serious training very soon.
RIP Tyler
ETA: I just read T-Rex's post and I agree...seems like there is a missing piece. What drove Tyler to commit suicide? Did he meet with his RA, GA or RLC and then return to his room? Somethings missing...what happened between this time and his post about jumping off the bridge?
