I am almost certain he fell and did not jump. he was sitting on the ledge of the riverwalk and from what I gathered from his friends, he fell in. again, didnt see it but heard the splash. forgot to add an extra "heavily" to when I said a girl said he was "heavily drinking." she said "heavily heavily drinking" . I don't think there was even a reaching for help as he was gone as soon as he fell in, there wasn't a struggle. Drinking that heavily plus most likely hitting his head bc it was an extremely narrow space = gone
