Investigators from Hunter Valley Police District have renewed their appeal for information ahead of the 25th anniversary of 17-year-old Allison Newstead’s death, NSW Police say.
Allison was last seen by her parents on Wednesday 6 October 1993, when she left their Cessnock home, heading to a café.
She was reported as missing the following day (Thursday 7 October 1993), when she failed to return home.
Her body was found by police seven days later (Wednesday 13 October 1993) at an abandoned colliery in Pelton, about 8km south-west of Cessnock.
Extensive inquiries have been made to determine the circumstances surrounding Allison’s death, which is being treated as suspicious.
On Friday 20 March 1998, the NSW Government announced a $100,000 reward for information leading to the arrest and conviction of those responsible for Allison’s death.
Hunter Valley Police District Commander, Detective Acting Superintendent Chad Gillies, said the $100,000 reward was still available today and urged anyone with information to come forward.
"We believe there are people who know exactly what happened to Allison but are either afraid, or unwilling, to share that information with police," he said.
"We urge these people to do the right thing and contact Crime Stoppers.
