Police are appealing for public assistance following the death of a woman on the state's Far North Coast last month.
About 6pm on Saturday 10 October 2020, officers from Tweed/Byron Police District were called to a unit on Elfran Avenue, Pottsville, after a family member found 44-year-old Elizabeth Britton with serious head injuries.
She was treated at the scene and taken to Tweed Heads District Hospital, before being transferred to the Gold Coast University Hospital where she died on Saturday 24 October 2020.
Tweed/Byron detectives commenced an investigation under Strike Force Sardonyx into the circumstances surrounding the incident to determine how and where Ms Britton sustained her injuries.
Tweed/Byron PD Crime Manager, Detective Chief Inspector Brendon Cullen, said he believed there are people who know how Ms Britton came to be injured that day.
"Ms Britton was in an extremely distressed state when she was located by family members that day.
"There are people who know how Liz came to be critically injured and how she sustained her injuries," Det Ch Insp Cullen said.
Liz's father, Colin Britton, said he simply wants to know what happened.
"Anyone who spoke with her that Saturday – a friend, a passerby, a neighbour – anyone that can piece together her movements and who she was with, please come forward to police."
As investigations continue, strike force investigators are appealing for anyone who may have seen or heard any suspicious activity in the nearby area in the hours leading up the discovery of the injured woman to contact Tweed Heads detectives or Crime Stoppers on 1800 333 000.
Anyone with information about Strike Force Sardonyx is urged to contact Crime Stoppers: 1800 333 000 or https://nsw.crimestoppers.com.au. Information is treated in strict confidence. The public is reminded not to report information via NSW Police social media pages.
