Massive crocodile believed responsible for killing man on vacation with wife and kids in Australia

Authorities killed on Monday a large crocodile thought responsible for Australia's second fatal attack in a month.

The latest victim was a 40-year-old man from New South Wales state who had been fishing on Saturday while on vacation with his wife and children, traveling through Queensland state with a trailer, according to police. Government conservation officer Daniel Guymer said the man fell into the Annan River south of Cooktown. His body has not been recovered.

Cooktown resident Bart Harrison said the steep bank had collapsed underneath the victim's feet, sending him more than 20 feet into the river which is renowned as a crocodile habitat.
