To live or to disappear?

I live in a very Torah-oriented area and there is a man there who is defined as a Chabad emissary.
Not that he needs to convince anyone to put on tefillin…
 
But he has several activities a year.
He distributes honey cakes 🍯 at the synagogue on Yom Kippur Eve
Taking care of some kind of procession on Lag BaOmer
And also gatherings that mainly come from children from Bit Kislev
And so does the revelry on the 3rd of Tammuz.
Why the jubilation?
1
1 of their parents has been released from some prison somewhere again
2
It’s a day of sunshine 🌞 in Gibeon Dum and a moon 🌒 in the Ayalon Valley
3
This is the day that many of us have lost sight of, and therefore we are rejoicing.
 
I ask
1
Is there any date in the year when one of their ancestors did not enter or leave some prison? Or at least be interrogated or tried?
2
When someone goes missing and goes looking for them, the police are called, and volunteers are called to look for them, they don’t make a fuss…
Perhaps he also understands that he is simple and pure, but that is “like a pervert” and therefore says “disappeared from our sight”…
