Accused murderer Caroline Dela Rose Nilsson has returned to the suburban Adelaide home where she allegedly bludgeoned her mother-in-law to death, then told police they had been the victims of a violent home invasion.

On the second day of her Supreme Court trial, Caroline Nilsson and jurors visited the house at Valley View, north of the CBD, where her mother-in-law, Myrna Nilsson, was found dead in the laundry in September 2016.

A heavy solid-metal doorstop in the shape of an orange tree – which was bloodstained and “consistent … with the kind of weapon that could have caused Myrna Nilsson’s head injuries” – was discovered nearby her body.

Wearing all black and accompanied by her lawyers, Caroline Nilsson, now 29, returned to the area neighbours found her “moaning and groaning” with her hands and feet bound about 10pm on the night of the alleged murder.

At the opening of the trial, jurors heard she told police two or three men with “loud and angry voices” arrived at the home with Myrna Nilsson when she returned from work.

She allegedly told police that, during the home invasion, the men had assaulted her and tied her up with speaker wire and tape before they ransacked the house.

“It’s the prosecution case that the story about other men being there is a fabrication which has been conceived and repeated by Caroline Nilsson to cover the fact that she killed her mother-in-law in the laundry of the house that they shared,” prosecutor Emily Telfer SC told the jury.

Ms Telfer said data collected from an Apple watch worn by Myrna Nilsson, 57, will show a “flurry of activity” recorded about 6.30pm that night.

“After that flurry, all movement stops,” she said.

“On the prosecution case, this is a record of Myrna Nilsson fighting for her life in an attack.”

The court heard the attack must have happened shortly after Myrna Nilsson arrived home because the bluetooth in her car disconnected 47 seconds earlier.

Ms Telfer said less than an hour later, at 7.08pm, data collected from Caroline Nilsson’s phone showed she opened the eBay app after her husband texted her about buying tools.

Caroline Nilsson’s three children - then aged five, three and one - were found inside the home later that night.

After visiting the Valley View house on Wednesday, jurors heard from crime scene investigator Brevet Sergeant Corey Pearson.

Under cross-examination by defence counsel Heath Barklay QC, Bvt Sgt Pearson agreed that, in almost every room of the house, drawers and cupboards had been rummaged through.

He also agreed police could not know whether jewellery or a large sum of cash had been taken from the property.

Caroline Nilsson has pleaded not guilty to murder.

The trial is continuing before Justice Chris Bleby and a jury.
