I read that they found his body in the water. Not really familiar with the area but seems strange that he would jump into water if he wanted to die. (I suppose it could have even really shallow but i read that divers were sent to find the body). I know, I know "it doesn't matter how he died. It's just said" but it's hard not to wonder.
He jumped off of a tall ass bridge. Apparently he had recently found out he had an inoperable brain tumor.
