A Victorian man who told police he may have been the father of Krystal Fraser's unborn child after she went missing has changed his story.
Ms Fraser, who was intellectually impaired, disappeared from regional Victoria while heavily pregnant 13 years ago.
The 23-year-old discharged herself from a Bendigo hospital against medical advice on the night of June 20, 2009, before jumping on a train after telling people she wanted to go to a party in Cohuna.
