Friends of a hiker found dead beside an SOS sign on a Lantau hillside in January have called for an inquest. Police officers investigating the death of English teacher Keith Gibbs, 55, said last week they would not be recommending an inquest because the case was 'not in the public interest'. Gibbs' friends insist the rare circumstances warrant one. A villager came across the decomposed remains of Gibbs about 10 weeks after he went missing. His body was partially submerged in a stream next to an SOS sign he had made using rocks. Police ground and helicopter searches of the island had failed to find him. The autopsy results were inconclusive because of decomposition, but showed he had not suffered broken bones and there were no traces of food in his stomach. Friends believe Gibbs, lightly clad in a shirt and a pair of shorts, fell from a ridge above the village of Pak Mong and injured himself, too far away for his cries to be heard. But unless he suffered a sprain, this now seems unlikely. Former employer Oliver Davies said: 'I would imagine he starved to death. I am just amazed that this could happen in Hong Kong, in what must be one of the most crowded places on the planet; that you can just disappear into the wilderness and starve to death. 'There should definitely be an inquest to find out what went wrong. I would be outraged if there wasn't one. Of course there is public interest, it was on the front pages of the newspapers. 'You certainly have to look at police procedures and how this could be avoided in future. You could see from the number of people who turned out for his funeral there was a heck of a lot of interest.' Friend Katie Webb said: 'This is such a mystery. He knew Lantau very well and walked there every weekend. There should be an inquiry because I don't want it to happen to anybody else.'
