I am not much of a conspiracy nut, But i SWEAR TO GOD, His death is a conspiracy. If you lived in aus and gave your attention to this **** , you'd notice something was fishy (no pun intended)
When he died, His adverts for the zoo in Queensland still were going until a few months later where they cut out all footage of him, and then a few more months later, his daughter filled the gaps.
The family didn't MOURN him at all, no they went places pretty much to "Promote" his death etc etc, After his death his family got SO MUCH for what they do, A few TV shows, late night talk show guest spots, etc.
I wouldn't be surprised if Steve is sitting in a Rain forest mansion somewhere, sipping tea leaves and living the high life as his family profits off his "Death"
