HOMICIDE detectives have renewed their calls for public information surrounding the murder of a young NSW woman more than 20 years ago.
On the morning of July 8, 1991, Penny Hill, 21, was found unconscious and bleeding next to a gate near Coolah, in the state's west.
She was taken to a Newcastle hospital where she later died.
A $100,000 reward is on offer for information leading to a murder conviction.
Police are particularly interested in speaking with anyone who stayed at the Black Stump Motel in Coolah during 1990-91.
An inquest into Ms Hill's death is expected to resume in the NSW Coroner's Court mid July.
