Tamika Chesser, 34, remains in police custody at a mental health facility in Adelaide after officers were called to a fire at the yard of their Flinders Highway home in Port Lincoln on June 19.

Police allege the former Beauty and the Geek dismembered Story’s body, leaving it without a head, two days before the fire.

A multi-agency search crew have been extensively scouring the Port Lincoln area for Story’s head.

Today, Major Crime Investigation Branch Detective Superintendent Darren Fielke said new information and specialist equipment had helped identify several more sites to search in and around Port Lincoln.

“New search areas have been identified and by undertaking these renewed searches, we hope to find Julian’s missing remains, which will give comfort to his family and allow them to peacefully lay him to rest,” he said in a statement.

“Police have reviewed a significant amount of CCTV footage since the incident which has provided a number of investigational leads.”

The sites will be searched over the coming days.

Late last month, police released vision of who they believe to be Chesser a few hours before the alleged murder.

The woman in the footage is seen walking with a dog.

Her sister previously told 9News that Chesser had been checked out of a mental health facility in Port Lincoln just weeks before the alleged murder, despite her family’s pleas.

She said they had been concerned about her mental health for months. 

“It’s my sister, but that’s not who she is or the Tamika we know. That’s not the Tamika anyone knows,” she said.

Anyone with information that may help the investigation is urged to contact Crime Stoppers on 1800 333 000.
