A hand-drawn etching of Sherryn and Shanelle Dawson. Chris and Lynette Dawson on their wedding day in 1982. A hand-drawn etching of Sherryn Dawson. SISTERS Shanelle and Sherryn were aged just four and two when, just before Christmas in 1981, their adoring mother Lynette Dawson ordered drawings of the pair from a Sydney artist. But the etchings were quickly forgotten when the 34-year-old mother vanished from her northern beaches home in suspicious circumstance not long after. Now, 32 years on, the haunting charcoal drawings of Shanelle and Sherryn have been unearthed by police and, according to Lynette's family, are tangible proof she did not "run off," as suggested by her then estranged husband Chris. "This was a wonderful mother who commissioned these drawings, got the girls to pose for photographs for the artist and then is supposed to have vanished before seeing them?" her brother Gregory Simms said. It doesn't make sense. Lynette wanted this artwork to keep. She would never have left her children and this is something solid from around that time that shows she had no plans to leave them. Towards the end of January, 1982, the artist had finished and went to the Bayview home with the etchings. She was allegedly told by Mr Dawson, a former first grade rugby league player, that his wife did not live there anymore and did not want the drawings. Of course Lyn wanted them. The family have come to the realisation she is dead. Two coronial inquiries have stated Lyn was murdered by a known person," Mr Simms said. Last year the artist remembered the drawings and the police were informed, along with Lynette's family. What we can't understand is why no one has been charged. The drawings are one of the last things she did, showing how much she loved her children and again proof she did not run away," Mr Simms said. Evidence given during the coronial inquests revealed Mr Dawson, who now lives on the Gold Coast, was having an affair with schoolgirl Joanne Curtis, a 16-year-old babysitter who sometimes stayed at the Dawson home. Within days of Lynette's disappearance, the teenager moved into the family home full-time. She later married Mr Dawson and had a child. At a coronial inquest Ms Curtis, now divorced, told the court Mr Dawson once said he wanted to hire a hitman to kill his wife but was worried innocent people would get hurt. He has consistently denied anything to do with his wife's presumed murder and has insisted she is still alive. "No one believes Lyn is alive no matter how much we want it to be," Mr Simms said. The police, two coroners and just plain common sense tells us she is dead. What we want now is to see someone brought to justice for her death. The DPP has consistently refused to bring charges against anyone. The case remains open.
