Ms Neilan was known to take walks through the quiet streets of Lightning Ridge with her dog, Sooky. Last week, she left home for a walk alone and never returned.

NSW Police are appealing for information about the suspicious death of the 39-year-old Ms Neilan, whose body was found in bushland of the small outback town late last week.

Ms Neilan's daughter Julianne, 22, broke down as she appealed for anyone with information to come forward.

"Mum is a loving, beautiful, caring person that would never even hurt a fly.

"We just want justice. We want somebody to come forward."

Ms Neilan's sister Shaunna Dench, 29, insisted the family would fight for justice.

"Somebody in Lightning Ridge knows something. Please come forward and tell police everything you that you know.

"My sister did not deserve this and we will get justice."

Homicide Squad Commander, Danny Doherty says a taskforce has been set up to investigate Ms Neilan's death.

"She's from a large family, her Mum lives in town, you know it's a sad time for them, in they want answers to what happened," he said.

"I'm sure there are people from that area who know what happened to her."



Police say she left her home last Wednesday, wearing an orange and blue short-sleeved shirt with an Indigenous pattern and black shorts.

Officers were called to bushland near Sunflash Street and Black Prince Drive last Thursday and discovered Ms Neilan's body.

A post-mortem determined she had died from serious head injuries.

"Police are particularly interested in speaking with anyone who had contact with or saw Christine in the 24 hours before her body was located," Det Supt Doherty said.

"On Wednesday last week, we know that Christine left home for a walk alone, without her dog and did not return.

"We urge any member of the community who may be able to assist detectives with their investigation to come forward and help us provide answers for Christine's family."

Ms Neilan and her mother moved to the area, located in the state's north-west near the Queensland border, late last year.
