Her sister Tahnee Easey said she was "broken into pieces" over the death Danielle Easey was never reported missing as it was common for her to "disappear for weeks at a time"

Danielle Easey, 29, was brutally murdered before her body was found by motorists in remote bushland in Killingworth near Lake Macquarie.

Police said she had not been reported as missing.

Her sister, Tahnee Easey, said she was struggling to "process something like this" and that her heart was "broken into pieces".

"I love my sister, my heart is aching for her and for her beautiful children," Ms Easey posted on Facebook.

"You may not be with us anymore but I'll forever carry you with me and cherish our amazing times and even our down times.

"I love you so much Danielle, you're and always will be my best mate."

Her brother, Brendan Easey, also posted a tribute on social media.

"My heart is terribly, terribly broken," he said.

"Right now I'm not OK. I'll hold up. Spend your thoughts on a memory of Dell, my little sister."

The ABC understands Danielle Easey was based at her mother's Booragul property but had been couch surfing at the homes of friends and associates.

Police were hoping to speak to anyone who met her over the past few months.

Ms Easey had been battling drug addiction and mental health issues, but she was never reported missing because it was common for her to "disappear for weeks at a time", the ABC understands.

On Facebook, Danielle Easey was listed as "in a relationship" with Benny Todd, who is in Cessnock jail after being arrested last month.

It is not suggested Mr Todd had anything to do with her murder.

Danielle Easey's body was found three days after she was due to face a range of offences at Newcastle Court, but detectives are yet to work out why and when she was killed.
