How common is it to be in the same house while someone suicides?

This was my experience. About 13 years ago. And method was a sharp object. The wildest part? I have another family member who has schizophrenia (developed 3-4 years prior) so our household was used to crazy behaviour and heightened situations. For this reason, I assumed my dad would survive until first responders said he has not. I don’t really ever tell what happened because it seems a bit extreme. It is extreme I guess but also my experience? While it definitely was traumatic, I am glad I never had to find out from someone else. Or be left with questions. Anyone with a similar story?
