THE former reality TV star charged with the murder of her partner was acting strangely in the weeks beforehand, locals say.

Unusual videos featuring Tamika Chesser from Beauty and The Geek have emerged while authorities are on the hunt for the missing head of Julian Story, who was reportedly decapitated by her on June 17 in southern Australia.

Police allege Tamika, 34, murdered and dismembered Julian, 39, on the bathroom floor of his home in Port Lincoln.

She then allegedly disposed of the victim’s head, carrying it in a bag and dumping it in an unknown location.

Tamika was arrested at the scene and charged with murder two days later.

Police and emergency services are scouring cliffs and waters off the Eyre Peninsula for the missing head, Daily Mail Australia reports.

Bizarre CCTV released by police – along with videos filmed by locals – shows Tamika acting strangely in the weeks leading up to the murder.

Footage obtained by Channel 7 shows her at a Port Lincoln hotel wearing a long dark wig and a hat before ripping it off and screaming.

Two locals told Daily Mail Australia they’d only ever seen Tamika with a shaved head since she arrived in town months ago.

In another video, she is seen doing gymnastics on bars outside a coffee shop.

In a third video, Tamika is seen wearing a wedding veil and standing bare-chested at the Port Lincoln War Memorial. 

The police have previously released CCTV images and photos showing a woman they identify as Tamika Chesser walking through Port Lincoln just hours after the suspected homicide.

Detective Superintendent Darren Fielke informed the media last week: “Although I cannot provide further details at this moment, it is with sadness that I report we have yet to locate Julian Story’s head.

“I can only imagine, and I want you to imagine, the grief this news is causing Julian’s family.

“Recovering Julian’s head to return it to his family so they can have a peaceful outcome, have a funeral and lay him to rest is a really important aspect for us.”

Supt Fielke added: “I’m appealing to local residents to review CCTV or dash cam footage which they may have, which may assist the investigation.”

Court documents earlier revealed officers found Tamika sitting in the back garden of the property “in a catatonic and unresponsive state” before her arrest.

She was also charged with disposing of human remains to pervert the course of justice and assaulting a police officer, The Telegraph reports.

Police have so far not been able to find a motive, with Assistant Commissioner Ian Parrott admitting there were still “a lot of unanswered questions” in what he described as a complex crime scene.

A suppression order protecting Tamika’s identity and banning publication of the alleged circumstances of Julian’s death was lifted on Friday.

The ex-reality star, who appeared via video link, has been denied bail and remains under a mental health detention order ahead of a committal hearing set for December.

Tamika’s sister, Kiya-May, claimed her family is devastated by reports she’d been charged with murder.

She told Daily Mail Australia: “Please report how my sister is in a mental psychosis… This is not her… She would never do these things.”

She added her sister had suffered “a life of trauma and abuse, and now this – it has fried her brain”.

Meanwhile, Julian’s grieving family has thanked police, emergency workers and the community for their support during what they called an “unimaginable loss”.

“Your care has brought comfort amid the chaos,” they said.
