Major search for man's head paused as Aus police trawl CCTV

A search for a man's decapitated head has been paused as police review CCTV footage to pinpoint the movements of the ex-reality TV star accused of his murder.

South Australia Police have been searching for the head of Julian Story, 39, after his dismembered body was found by authorities called to a unit fire at Port Lincoln on June 19.

Police allege Story was killed about midnight on June 17 and his head was removed during the dismemberment.

Tamika Sueann Rose Chesser, 34, a former Beauty and the Geek contestant, has been charged with his murder after a court revoked an order suppressing her identity on Friday.

A police search for Story's head has spanned Port Lincoln reserves, parks, bushland, the ocean, pier and bay areas and involved state emergency service volunteers, water police, divers and local patrols.

But investigators today said the intensive search had been put on hold while police turned to reviewing a significant amount of CCTV footage to find other locations of interest.

Authorities are appealing for any footage the public can share with police to progress their investigation.

"Police are trying to track Tamika's movements in the week of the murder, particularly between midnight on Tuesday night and the report of the fire at 3.30pm on Thursday," SA police said in an update.

"Major crime detectives have released images of the clothing she was wearing during this time in the hope that it will jog people's memories."

Police were releasing details of the "horrific" crime as it was vital for the family of Story to be able to peacefully lay him to rest, Detective Superintendent Darren Fielke said.

"We know that Tamika did not drive a vehicle and regularly walked around the township of Port Lincoln," he said.

"We are appealing to anyone who can help us to identify Tamika's movements to please contact police."

Police found Story's body after firefighters were called to a Flinders Highway property to investigate reports of a blaze.

Chesser, who police said had been in a relationship with Story for several months, was arrested on June 19 after Story's body was found at the couple's home.

She was known to walk through back streets and parks in the Port Lincoln area with her dogs.

She appeared by video link in court on Friday while being held under order at a forensic mental health facility.
