The death of a woman who left her mother's home in an outback NSW town without her beloved dog is being treated as suspicious.
The body of Christine Neilan, 39, was found in bushland in Lightning Ridge on January 9, with an initial post-mortem revealing serious head injuries.
NSW Police Homicide Squad detective superintendent Danny Doherty told reporters on Thursday Ms Neilan was unemployed and had moved in with her mother just before Christmas last year.
Originally from Gulargambone in NSW's central west, Ms Neilan was often seen walking with her dog Sooky but she went walking without it on January 8 around 10am.
"She was not heard from by her family until the discovery of her body," Det Supt Doherty said.
"I'm sure there are people from the area (who) know what happened to her."
Ms Neilan was wearing black shorts and an orange and blue short-sleeve shirt with an indigenous pattern when she was discovered.
