I would like to bring people to the table to focus on the chart .. I don't know how to post my version of hernandez's natal chart and progressions .. But in my opinion looking at transits is not productive of any true enlightenment here. Sorry if that seems harsh. The main factor here are three ..but first and foremost an extremely tight Jupiter opposite Saturn..(Jupiter retrograde singleton) ... The man agonized over his mistakes..(.. By .4 minutes of a degree..did I say that right?) ..
Then mars in Scorpio conjunct mercury ..combust to sun all approaching Pluto. We could say sun beseiged by mars and Pluto.
Then Venus conjunct Uranus then Saturn then Neptune .. Add sun square moon ..first quarter ..emerging moon .. Lunar return by progression .. Progressed Declination sun conjunct Saturn just entered cazimi
I agree with you about the Jupiter/Saturn opposition. I do think he killed himself because of pain and anguish over his many mistakes.
And the Sun besieged by Mars and Pluto makes a lot of sense. I think he was overwhelmed and felt powerless. He didn't see any other way out.
