The man who called a heavily pregnant Krystal Fraser just before midnight on the night she went missing was likely involved in her death, a Victorian coroner has found.
Ms Fraser, 23, was nine months' pregnant when she vanished from Pyramid Hill in the state's north after visiting a friend's house about 9.30pm on June 20, 2009.
No body and no criminal charges, her family has waited more than 13 years for answers.
