A FORMER reality TV star from Beauty and the Geek has been arrested and charged with murder after her partner’s body was found in their house.

Emergency services were called to the home in Port Lincoln, South Australia, to reports of a fire.

When they investigated, they found a man’s body inside.

The unnamed 34-year-old was arrested at the scene and later charged with murder.

She was once a contestant on reality show Beauty and the Geek, reports The Courier Mail.

The social experiment programme brings together attractive women with nerdy men in a mansion.

The victim and the suspect had been in a relationship together, South Australia Police confirmed.

The woman refused bail and remains in custody.

Major crime investigators and forensic officers were flown into Port Lincoln to assist local authorities with the investigation.

Neighbours were shocked by the news.

One told Perth Now the woman is “really nice, very pleasant, polite.”

Ian Parrott, of South Australia Police, said: “I can reassure members of the community that this is not a random incident.

“We understand that the female who has been arrested and the deceased male both lived at this address.”

It is understood the couple had recently moved in together.

He noted: “This investigation is still in the very early stages, and it is anticipated that the Major Crime investigators along with the forensic response teams will be on site for most of the day.”

Parrot mentioned that the cause of death remains undetermined, adding that more information cannot be shared yet because the victim’s family has not been informed.

The woman has been detained under the Mental Health Act and did not seek bail.

She is expected to return to court in December.

A suppression order has been issued which prohibits the release of any information that could reveal the woman’s identity, the identity of the victim, or specifics related to the man’s death.

That order is due for review by the court next week.
