Wow, that's fucked up. I'd go with an accident, there's been quite a lot of Balcony fallings due to the metal railings breaking when people lean towards them or anything else they do on a Balcony. I don't suffer from vertigo, but I'd and haven't ever leaned toward over a balcony.
This is a very recent case, the forensic dude who shared may leak more. If he does I will post, make sure you visit CDG regularly I promise if anything new comes up I will add - for now it's just this one goddam pic.
