From Dustin's last myspace blog on the day he died -

It had to be done, I'm sorry
Current mood: anxious

Sorry, you know who you are. I am sorry for what I did but I felt it was the only way to deal with the situation. I know I hurt you and you will probably never forgive me for what I felt needed to be done, but that is life and we all have to take a stand and do what we think is right. Maybe I'm selfish, but it is just as selfish to tell me how to live my life to make yourself happy. Perhaps someday down the road we will somehow meet in another context and solve all this shit, for now I am sorry for what I have done.
