Channel 7 are currently running with Suicide saying that a note was found.
If it was and there was a note, what a selfish waste of peoples time and endangering the lives of others to recover the mess. It's like when I once heard about a skydiver who decided to end things at the local skydiving club to the dismay of many spectators and young children. I'd like to know what drives a person to go to those lengths; it's just so unfair.
