I see no dates, names, details or basically anything of substance relating to the suicide threat story. It seems to just be one of those sourceless rumours that get passed around as gospel.

Note in particular that the commentator does not say they saw this or even that someone who saw it told them. You're just hearing a rumour this person heard at MIT.

I don't see any reliable source there. Are some of those profiles verified? I also didn't see any reference to suicide.
