Thank you Jamie for speaking out on this heartbreaking tragedy. Too often, the family of a suicide victim will not disclose siicide as the cause of death. I agree that a response is necessary - I doubt that anyone really believes deep down that their son, daughter, friend, co-worker, is really going to commit suicide. 
If you suspect someone even might be thinking of suicide, do something. It will require more than just taking he gun away or saying "it'll get better". Get professional help. It won't stop every suicide, but it might stop just one.
