I'm with Elbert on this one. Killer Croc my aunt fanny.
I don't think that boy went for a late night swim and the croc attacked. Chances are the croc was being opportunistic when it saw a potential meal in his lagoon.
It is absolutely horrible what happened to this poor guy. They should stop worrying about the crocodile so much and figure out why Wilber was in the lagoon in the first place.
Just my opinion.
