Penny Hill, then aged 20, was found unconscious with severe head and facial injuries on Cassilis Road, near Coolah, about 8am on Monday, July 8, 1991.
She was taken to Coolah Hospital then airlifted to John Hunter Hospital, where she died two weeks later, on Sunday, July 21, 1991.
In 1992, a coronial inquest held in Mudgee returned an open finding on the cause and manner of death.
Detectives from the State Crime Command’s Homicide Squad began further investigations into Penny’s murder under Strike Force Samdon, before a second coronial inquest was held in 2012.
The second inquest also delivered an open finding and was returned to investigators, who pursued a number of new lines of inquiry, however, no one has ever been charged in relation to Penny’s death.
Two years ago the NSW government increased the reward for information which leads to the arrest and conviction of those responsible for Penny’s murder to $1 million.
“Detectives have made a number of public appeals to the community for any information that could help investigators solve this horrific murder,” police said.
