I was only ever able to confirm one suicide, a while back, as actually having occured, as there was enough information in their help/goodbye thread to creatively conduct a search and connect their username to an irl name. I'm not going to name this person, but her name has been mentioned in other threads previously. She died by CO poisoning. Most successful ctb's, though, are never confirmed, and all we have to go off of is anecdotal evidence. I think there is a website, the name of which escapes me presently, that did a story on SaSu, which, also, presents a "list" of past SaSu members who have taken their lives. The story is written as an attack against SaSu, though, and the carnage they have inflicted on society.
