Tamika Chesser, aged 34, is currently held by police in a mental health facility located in Adelaide. Authorities were alerted after a fire broke out in the yard of her residence on Flinders Highway 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.

Major Crime Investigation Branch Detective Superintendent Darren Fielke announced today that new data and advanced equipment have led to the discovery of several additional locations to investigate in and around Port Lincoln.

“By identifying new areas for searching, we aim to locate Julian’s missing remains, providing solace to his family and enabling them to give him a proper and peaceful burial,” he stated in a press release.

“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.
