I live in LA but I'm not familiar with that area. It has been all over the news that the place he fell was less than a mile from his home. Of course one can't rule out suicide, but from what I know of Danelo, it isn't likely.
It's a grassy park that goes right to the edge of the cliffs. I could imagine friends partying there at night. But why wouldn't the others have noticed he was missing? Prayers for his family. Very sad.
