Woman went on deadly frenzy after man told her to

A Brisbane woman armed herself with a knife and warned people were "going to die" before she went on to stab five men in a psychotic episode, killing one of them.

Natascha Mielke was suffering from a mental illness on the night of May 12, 2017, when she entered a Paddington hostel armed with a knife.

The Brisbane Supreme Court today heard Mielke, now aged 43, had been drinking with another man in a Brisbane park when he suggested she kill someone, telling her he had a knife in a nearby toilet block which she retrieved.

Crown Prosecutor Dejana Kovac said Mielke had previously been a residents of the Pinjarra Lodge, an accommodation support service for people with mental illnesses, but had been asked to leave a year earlier for drinking alcohol and starting fights with other residents.

Ms Kovac said Mielke walked in to the lodge with the knife hidden up her sleeve and went into the bedroom of two men where she sat on the floor for about 30 minutes and at one point told them they were "going to die" and that "she loved them".

Natascha Mielke has pleaded guilty to a stabbing frenzy at a Brisbane hostel that resulted in the death of one man, and injuries to four others.

"She then left the bedroom and went into (another man's) room, that particular person was also in bed at the time she then stabbed him in the chest once," Ms Kovac said.

She then went back into the room where the first two men were sitting in their beds.

"She first attacked (one man) with a knife who told her repeatedly no and not to do it, she wouldn't listen and she stabbed him once in the abdomen," the prosecutor said.

"(His roommate) then tried to intervene and she then turned towards him and stabbed him in the stomach."

Mielke then left the building and approached another man outside who she stabbed to death.

The court heard there were no witnesses to the attack and the victim was found with injuries to his back and abdomen.

"He was found lying on the ground face down and the medical report suggests that due to the nature of his injuries … at least moderate force was used to inflict those injuries."

Mielke then returned to the park where she had been drinking and stabbed the man who had told her to kill someone and provided her with the knife, chasing him when he tried to run away.

The court heard Mielke had previously been in a sexual relationship with two of her victims and that all of the men were known to her.

Defence barrister Katarina Prskalo said Mielke was "clearly psychotic" at the time of the offences and was "extremely remorseful for her conduct".

"She regarded the victims as friends of hers and it is very distressing to her to know that as a result of an exacerbation within her mental illness that she hadn't controlled or contained well over many years that she was capable of doing something such as this," Ms Prskalo said.

She said a doctor had described her conduct as "bizarre" and it was as though "her brain was not functioning".

"She was heard by independent witnesses engaging in a fairly animated or hostile conversation with what is essentially a non-existent being," Ms Prskalo said.

"There was a source of dissension from her and blame she was placing on this other person who told her to do something."

Mielke pleaded guilty to manslaughter and four counts of malicious act with intent.

Justice Jean Dalton reserved her decision and Mielke will be sentenced at a date to be set.
