Mersina Halvagis never thought she would be murdered in a cemetery. No reasonable person would.

It was 17 years ago on November 8, when Ms Halvagis, 25, went to the cemetery by herself to visit her grandmother’s grave.

Unfortunately, serial killer Peter Norris Dupas – one of Australia’s most depraved misogynists – was also at the cemetery that day.

On Saturday, Ms Halvagis’s family gathered at her grave to mourn her passing.

Up to $3 million has been spent by Victorian Legal Aid, the Office of Public Prosecutions and the courts in 33 legal proceedings since Dupas was first charged with murder.
