Oh dear, so sad
His birthday is the day before mine, so like Flapjacks I always felt an affinity for him.
Coincidentally I was reading about talking to people who are grieving recently, and the advice given there was that how and why a person died is such a small part of their life that it is better to focus on what they did when they were alive, which is so, so much more.
Mork & Mindy was an integral part of my childhood, I was inspired by Dead Poet's Society, Aladdin is one of the best Disney movies in my opinion, not least because of the Genie, I loved the Fisher King and even One Hour Photo, creepy though it was. And then there are all the really funny and hilarious moments, too many to mention specifically.
Having said all that though it is interesting (if that's the right word) that if scorpio is his ascendant then the ruler of the 8th house, mercury, is conjunct the ruler of the 1st, and both on the MC - a signature for a high profile suicide. I don't want to suggest that everyone who has this will die the same way, it is just one way that it can manifest.
If we take mars as the ruler of scorpio that is being opposed by pluto and affected by the grand cardinal crosses that have been going on recently, as hermetic says, and saturn crossing his ascendant can make a person feel like the weight of the world is on them, as ashriia mentioned.
& if the chart posted is correct, the full moon on 10th August activated his IC, which is the point of the end of life, by a conjunction of 4 degrees (18'02 Aquarius) and opposed his MC, so also triggered a lot of attention for his career and public profile. It also opposed his natal pluto (as ashriia already said).
I'd be interested to know what his progressions, solar arc directions and solar return for this year were. The solar return might be especially important as it is only 3 weeks since his birthday.
Also a controversial theory, less astrologically referenced, and one that I definitely don't want people to feel condemned or doomed by, but there is a book called "The Secret Language of Relationships" which is loosely based on astrology and divides the signs into weeks. Those born in the week of the Cancer/Leo cusp are described as being prone to depression, and a notable example given is Ernest Hemingway, whose birthday was 21st July 1899 and who also committed suicide.
I still think it is so sad, and so unnecessary, when people commit suicide though. But perhaps if I was in their position I would understand.
