 This is Acting Superintendent Mick Bianchi from the South West Police District. Police from the South West are continuing to search for 37-year-old Stephen Van Longkeusen and his two children, aged 7 and 5, who are missing somewhere in Central West Queensland. Police have been out searching for several days in their area from miles to room to Rolleston, particularly in the national parks. Today we are focusing our attention on the Isle of Gorge and Presbyst National Parks and also Expedition National Park. Other searches are occurring further to the north. We have a search and rescue coordinator on the ground looking to establish if an air search is possible. The search area is several hundred thousand square kilometres in size and police can't do this alone. We have been appealing to the public for assistance to locate Stephen and his boys and despite quite a number of calls there is still no sign of them. I thank those people who have already called for their assistance. We are concerned for Stephen and the boys' welfare. They have not been heard of from 11 days now. The weather conditions in the search area are extreme and we are concerned for them. Stephen and the boys are travelling in a white 1995 Mitsubishi Pajero registration number 426MCZ towing a grey trailer covered by a blue plastic tarpaulin. Stephen was intending to travel to Cairns via an inland route and has not arrived. He has not made contact with his family or friends. Stephen indicated that he might go camping and we believe that they may be camping out of mobile phone range. We believe it is possible that they may have become stranded by recent heavy rain. We again ask all members of the community including truck drivers, graziers and farmers, campers and the motoring public to be our eyes and ears and assist us to locate Stephen and his boys. Everyone can help by being vigilant and watchful for any sign of them. The more eyes we have out there looking, the better chance we have of finding them safe and well. Any information can be reported to Police Link on 13 14 44 or to Crime Stoppers on 1800 3 3 00. Thank you.
