A friend of Kristie Powell found the 39-year-old's body at the home in Bellambi, north of Wollongong, early on Friday morning and called authorities.

The victim's five-month-old son was also found unharmed inside the house.

On Saturday morning, police released a photograph of 29-year-old Bhanu Kirkman.

There is an outstanding warrant for Mr Kirkman's arrest regarding allegations of fraud, resisting an officer and drug possession, police said.

The 29-year-old is known to frequent the Illawarra, Shoalhaven and Sydney areas using trains.

Police urged anyone who has seen him or knows his whereabouts to immediately contact triple-zero.

Detective Inspector Brad Ainsworth said police believed Mr Kirkman could help them with their inquiries to "shed some light" on the overall investigation.

"He's had some minor dealings with the police, for resisting arrest and some drug-related possession, that's why he's the subject of a warrant. He has carried a knife before," Inspector Ainsworth said.

The officer yesterday revealed Ms Powell was covered in a "significant" amount of blood and a weapon may have been used in the attack, but he would not elaborate on her "serious" injuries.

Chilling posts on Ms Powell's Facebook account also show she was concerned about a stalker.

Six months ago, Ms Powell informed friends she no longer answered calls from private numbers due to the issue.

She said she sometimes received 100 calls or messages a day from the former employee who became "obsessed" with her and called himself "the reaper".

"Most of the time it is highly amusing and entertaining really," Ms Powell wrote.

"He needs serious help but the mental health system just keep releasing him."

Inspector Ainsworth said police were reviewing images on Facebook.

"We've reviewed some Facebook images, some commentary there, yes, there's some disturbing commentary there," he said.

Police have been collecting CCTV footage and conducting door-to-door inquiries since Ms Powell's body was found.

Her young son is being looked after by his grandparents.
