Journalists staking out the house of an Adelaide woman questioned over the alleged murders of Karlie Pearce-Stevenson and her daughter, Khandalyce Pearce, have been pelted with eggs by her boyfriend.

Hazel Passmore was questioned for several hours on Friday after it emerged photos of Khandalyce were uploaded to her Facebook page in 2008.

At the time Ms Passmore was living in Alice Springs with her ex-boyfriend, Daniel Holdom, 41, who has been charged with Ms Pearce-Stevenson's murder.

Holdom was arrested on Thursday by officers at Cessnock Police Station in the Hunter region of NSW.

On Saturday morning, Ms Passmore's current boyfriend swore at members of the media waiting outside her house at Davoren Park, and threw eggs at them.

Objects were also thrown from behind the house and over the roof, including a small piece of wood that landed on a car belonging to the house.

Ms Pearce-Stevenson was allegedly killed in December 2008.

Her remains were found in the Belanglo State Forest in New South Wales in 2010.

The remains of daughter Khandalyce were found in July near a suitcase about 1,140 kilometres away alongside a highway in South Australia's Murray Mallee.

Last week, police alleged Ms Pearce-Stevenson bank account was accessed hundreds of times over the years to withdraw almost $100,000 and her phone was used to contact family to make it look like she was still alive.

Khandalyce was two years old when she was last seen in 2008.

Ms Passmore uses a wheelchair after she and Holdom were in a car accident in September 2008, which killed two of her children.

Police would not confirm whether charges have been laid against Ms Passmore or are expected to be.
