KRYSTAL FRASER, 23, was last seen 20 June 2009, in Pyramid Hill, a small country town in Victoria, Australia. She was heavily pregnant and only days away from giving birth at the time of her disappearance. She was last seen wearing an orange top, black track suit pants and a camouflaged-patterned baseball cap.
Detectives have established that Krystal travelled on a V/Line train from Bendigo to Pyramid Hill on the day of her disappearance, getting off the train at Pyramid Hill Railway Station about 8.40pm.
Investigations have also revealed Krystal was last seen alive leaving an address in Albert Street, Pyramid Hill about 9.30pm after visiting an acquaintance.
She also received a phone call on her mobile phone from a public phone booth outside the Leitchville Post Office in Findlay Street shortly before midnight on 20 June, 2009.
It is believed that the caller was the last person to speak to Krystal prior to her disappearance.
Police have not been able to locate Krystals mobile phone.
Investigators believe Krystal was murdered and despite extensive investigations, are still searching for answers.
Homicide Squad Detective Inspector John Potter is hoping the $100,000 reward - offered since 2012 - will encourage anyone with information to contact police, in particular those in the Pyramid Hill, Leitchville or Gunbower communities.
Ms Fraser, 23, had an intellectual disability and was preparing to raise her first child without the father. The identity of the father has never been revealed, though several men have admitted relationships with her.
Detectives have interviewed some of the men, and cleared two others that have committed suicide since the disappearance.
