Did giant crocodile get eaten by great white shark?

It looks like this croc was beheaded by a huge shark, and its head washed up on the beach.
There is some debate to this though, some people think its poachers, but given the teeth marks in the side it looks more like it got captured by a shark as it swam up the beach.

Well, so one predator preys on another.

How ironic.

Sounds like Chicago...
