Official says mainland expert may be invited if John Lever fails in his mission Australian croc hunter John Lever got a surprise call yesterday - from Helen Lever who may be an unknown relative living in Hunghom. Helen's father, Gordon, who lives in Canada, is visiting Hong Kong and saw John's face in a news photo and on television. 'That looks just like my father,' he thought. His father Charles was one of nine siblings from Lancashire, England. Most of the family dispersed, some in the UK while others emigrated to Australia. The crocodile hunter, who lives in Queensland, was unable to catch the Yuen Long reptile last night - and a top official said a mainland expert may be called in. John's family emigrated to Australia from Coventry, and he was born in Melbourne in 1942. 'I think there's a good chance we're second cousins. We are about the same age - Gordon is 59 and I'm 61,' said John. His complicated family tree has been studied by his sister Pam, and he plans to ask her to investigate if he and Gordon are related. 'The resemblance to my father is uncanny,' said Gordon. 'It wouldn't surprise me if we are cousins.' Mr Lever set out at 4am yesterday for his third hunting excursion in Yuen Long. But the outcome was frustrating, he said. Instead of heading for the opposite bank where the lights are low, the crafty 1.2-metre reptile went in the other direction. 'He was right opposite the boat ramp on the industrial side of the creek,' said Mr Lever. 'The reflections of lights made the water like glass, so he could see us and went over to the other side. 'He popped up in Kam Tin River right at daybreak, which is not the time to catch him. Our best chance is if goes up the Kam Tin river near the driving school.' He also told of encountering 'the biggest rat I've ever seen' on the banks of the creek. 'I thought it was the croc's eyes and I was about to shoot the harpoon when I realised it was a bloody great rat.' Mr Lever plans to make more traps and add them to the five already set by Agriculture and Fisheries officers. He planned to head out again at 4am this morning for another hunting expedition. 'I hope it's third time lucky. People must understand that some crocs can take weeks or months to catch.' Last night the director of agriculture, fisheries and conservation, Thomas Chan Chun-yuen, said during a duty visit to Beijing that experts from the mainland could be invited to hunt the crocodile if Mr Lever fails in his mission.
