As far as I know, we are not keeping a count of people that are gone; there are some other registers but they are not relevant to this.
All I can say is that many have tried on the last 2 months and most of them we never saw back; which is always sad to know.
If you really want to count them, you can do it manually; but in my own opinion it does not really serve a purpose; their words are enough, they were humans with their own lives and pain, not a number on a sheet to keep track of.
Good luck.
