POLICE fear that an intellectually disabled woman who went missing days before she was due to give birth has been murdered.Pyramid Hill woman Krystal Fraser has been missing for almost four months and her disappearance is now being investigated by homicide detectives.Ms Fraser, 24, was last seen leaving a house in Albert Street, Pyramid Hill, about 9.30pm on June 20.Shortly before midnight, she received a call on her mobile phone from a public phone booth outside the Leitchville Post Office.The person who made this call is the focus of police inquiries into Ms Fraser’s murder.Homicide squad detectives and as many as 40 volunteers searched a property about 10 kilometres east of Pyramid Hill yesterday after receiving two tip-offs about the location of Ms Fraser’s body.Homicide squad Detective Sergeant Wayne Woltsche said police appealed for anybody with information about Ms Fraser to come forward.The father of Ms Fraser’s child is unknown, but it is believed she was expecting a boy.“We’ve got extremely grave concerns for her and it is our belief Krystal Fraser has met with foul play and has in fact been murdered,” Detective Sergeant Woltsche said.“Our inquiries have led us all around the area, including areas of Pyramid Hill, Gunbower, Leitchville, Cohuna and Swan Hill.“Inquiries we have conducted to this stage have not provided us with any information or evidence of Krystal Fraser’s whereabouts.”Detective Sergeant Woltsche said the homicide squad had become involved in Ms Fraser’s disappearance although no new evidence had been uncovered.“What we’ve established from our investigation is that Krystal Fraser was a person of habit,” he said.“She was very attached to her mobile phone and used it extensively, making numerous text messages, phone calls and accessing the internet via her mobile phone.“She was also very compulsive with her money, in that she would withdraw it as soon as she was paid.“Her bank account remains untouched. Further to that, her phone has not been used since (June 20).“Her family have celebrated a number of birthdays, Krystal herself celebrating a birthday, her sister had a 21st last week, she’s not been heard from, she has not attempted to make contact with any family member, which is highly out of character for Krystal.”Detective Sergeant Woltsche said police were no longer investigating the man who Ms Fraser visited in Albert Street on the night of her disappearance.
