Murder victim's parents sue Victorian government

The parents of a Victorian woman murdered by a man on parole are suing the state, representing the sixth family this year to do so.

Elsa Corp, 26, was killed by David Patrick Clifford in a brutal, drug-induced, psychotic rage in a Melbourne hotel in 2010.

At the time of the murder, he was on parole for drug offences and on bail after being charged with the violent assault of two men in 2008.

The hairdresser's parents, Gillian and Andrew Corp, are claiming the state was at all times responsible for Clifford, including assessing his suitability for release, creating suitable conditions of parole, monitoring him, and protecting the public from him.

They represent the sixth family of a murder victim to launch legal action against the government this year.

In June, the families of five people murdered between 2009 and 2012 - Sarah Cafferkey, Raechel Betts, Joanne Wicking, Evan Rudd and Douglas Phillips - lodged similar claims of negligence in a co-ordinated legal action that also includes two sexual-assault survivors.

All eight cases are being handled by Shine Lawyers, but it is not yet known if the Corps will join the other proceedings.

A Victorian government spokesman on Saturday acknowledged the "tragic and heartbreaking" losses and said the parole system had been comprehensively reformed in recent years.

The state government says it won't comment any further on the matter while it is before the courts.
