#hernamewas Gabriella Delaney. She was a 20-year-old woman from Western Australia who lived in Western Sydney. Gabriella was an artist - a woman who lived to create, to give back to the community and her friends have paid tribute to her, telling 9News "She was so nice and bright and smart," and "She didn't deserve it. (I) definitely think bad things always happen to the wrong people."
Detective Inspector Jason Pietruszka from Nepean Police Area Command described the scene as "confronting".
"The cause of death at the moment is being investigated," he said.
"By that I mean the lady had not been seen since June 3, so we are dealing with a situation where further examination is required to get an actual cause of death.
"We do believe unfortunately that it is foul play and it is being investigated as a homicide.
"It was quite a confronting scene."
