Multi-day search for missing woman ends in Central West

One Sunday the three-day hunt for Jessica Zrinski wrapped up in the Jenolan State Forest.

"A number of items were seized but have been assessed as being unrelated to the investigation," a spokesperson for NSW Police told the Central Western Daily.

The 30-year-old woman was last seen at Bossley Park in Western Sydney about 10pm on November 27, 2022.

CCTV shows her entering a Blue Holden Commodore, which then headed on the M4 towards the Blue Mountains.

The Central Western Daily previously reported a knife was found during police searches near Oberon. It's relevance remains unclear.

A $500,000 reward for information on the disappearance of Jessica Zrinski remains on offer.

"Living life without my baby girl Jess has been the most difficult pain I've ever had to endure," her mother Michelle Barton said in a statement.

"I've loved her for her whole life, and I'll miss her for the rest of mine.

"All I can hope is there is someone out there who can help us find Jess so we - her family and friends - can lay her to rest and say our goodbyes."
