The reward was announced in July 2019 but police admit it did not provide any insights into the 23-year-old’s case.
Krystal was last seen at a house in Albert St in her hometown at 9.40pm on June 20, 2009, and then simply vanished.
The case has devastated her family and baffled police for almost 12 years.
Now, there is a chance an inquest can re-examine the case in detail and possibly help solve it; with an inquest brief believed to total 5000 pages submitted to the Missing Persons Squad.
However, the sheer size of the brief means it will still take several months to process before an inquest date can be set.
Victoria Police confirmed the brief is still being prepared and any inquest will be a decision for the coroner.
The news comes after retired Victoria Police detective Dennis O’Bryan names his suspect in a book he is writing after months of his own investigating.
Mr O'Bryan believes the culprit was a man who likely fathered Krystal’s baby and used her as a drug mule and sexual plaything before killing her and dumping her body in one of the waterways around Gunbower.
Helping the Fraser family to finally find some answers, Mr O’Bryan is also pushing for an inquest to be held.
“An inquest is going to put more pressure on the crook,” he said.
“Suspects will be put in the box and expected to answer questions.
“It's also an opportunity for the family to get some answers and for Krystal's matter to finally be solved.”
Mr O'Bryan said the inquests into murdered teenager Daniel Morcombe and missing boy William Tyrrell both proved fruitful.
“We live in hope someone will step forward so this crime can be solved once and for all,” he said.
In a Riverine Herald special report, crime writer IVY JENSEN talks to Mr O’Bryan about what is needed to unravel the mystery and also speaks to Krystal’s family, who continue to live in hope justice will be done and they can finally lay their daughter and sister and her son Ryan - who would have been born just days after she disappeared - to rest.
