Story, aged 39, was reportedly killed by his partner, ex-reality TV star Tamika Chesser, after a minor fire at their residence in Port Lincoln, located on South Australia’s Eyre Peninsula, on June 19.

Today, a local discovered a human skull in a scrub area in Port Lincoln, six weeks after Story’s decapitated body was discovered in their unit.

Police believe Story was murdered at about midnight on Tuesday, June 17.

Fielke said police had not determined a motive.

Chesser was charged with murder, disposing of human remains to pervert the course of justice, and assaulting a police officer.

Her identity was revealed after Magistrate Ben Sale lifted a suppression order on it in Adelaide Magistrates Court.

She appeared in court via video link and was refused bail when she first appeared last week via a bedside hearing.

Chesser is being held under a mental health detention order.
