Police have renewed calls for assistance into a cold case murder.
21-year-old Narrabri woman Penny Hill was found bashed unconscious at Coolah, west of Cassilis, in July 1991.
She died two weeks later in John Hunter Hospital.
An inquest into Ms Hill’s death is currently in recess, as police seek information from anyone who stayed at Coolah’s Black Stump Hotel between 1990 and 1991.
A $100,000 reward has been offered for information leading to a conviction.
