As the third anniversary of the disappearance of Canadian tourist Ani Ashekian approaches, her two sisters are visiting Hong Kong, hoping to reignite the campaign to find her. Sossy Ashekian, 30, and Rosie Kampstra, 36, spent this week in the city, meeting police investigators and the Canadian consulate to kick start search efforts. They also handed out fliers outside Chungking Mansions in Tsim Sha Tsui where Ani was last seen. 'In the past 12 months there have been no new clues at all of her whereabouts, so that's why we're here - to try and get the investigation going again,' Sossy said. 'Over the past year it's just gone quiet and there's been nothing. We felt we had to come back and get Ani's disappearance back in the public eye.' Her family last heard from her on November 11, 2008, while she was in Hong Kong. Ani had been on a holiday through Asia. She had been visiting Beijing and travelled to Hong Kong. After staying in the city for a few days, she was due to fly to India before returning to Toronto. Nearly three years ago, a CCTV camera in Causeway Bay MTR station recorded the last known images of the 33-year-old, twice withdrawing money from an ATM. Police, local volunteers, private investigators, and even psychics have all tried to help. Officers have canvassed neighbourhoods and posted appeals on television and in police publications. However, it has all been to no avail. Guy Shirra, a retired Hong Kong police officer who investigated missing persons cases, is one of those trying to find answers. He has looked around the hills of Lantau, visited hostels and Buddhist temples, liaised with police, and talked to those involved in the initial volunteer search with the aim of drawing up a timeline from the time Ashekian left Canada to when she arrived in Hong Kong. 'I'm afraid that every line of enquiry is concluded and we're no further on at all,' Shirra said. What is known is that the Canadian arrived at Hong Kong International Airport on November 9, 2008, and was spotted at Chungking Mansions in Tsim Sha Tsui a day later. There is no record of Ashekian ever having left the city. There has been no activity on her mobile phone or bank account since her disappearance. Ashekian's family and friends have still not given up hope, however. 'We can't give up hope, we stay positive,' Sossy said. 'There have been lots of prayers and we still believe she can be found. We just want to remind people that she's still missing and we are still trying to find her. We're not giving up.' Rosie said: 'We just don't want people here to forget. We want Ani to know that we haven't forgotten either.' Both sisters praised Hong Kong police, saying that although there have been no leads they have kept the case open and have been very encouraging throughout. 'The authorities have been great here. They've always given us hope,' Sossy said. Anyone with information about the case can call the police investigation unit at 28607834. There is also a Facebook page called MISSING: Ani Ashekian.
