Until recently, Ms Dolheguy had two carers with her at all times, day and night. But it is unclear what – if any – mental health support was provided to her in recent months. The Age was told her 24-hour support had ceased and carers instead paid her regular visits. Police allege Ms Dolheguy killed Maulin Rathod at her home in Ross Court, Sunbury, after the two arranged through a dating app to meet there on the evening of July 23. The 25-year-old Elsternwick man was critically injured and taken to Sunshine Hospital about 9pm, where he died overnight.

Mr Rathod moved to Australia four years ago to study and was in the process of completing a master's degree in accounting. His parents in India are struggling to deal with the loss of their only son. Maulin Rathod. In public social media posts detailing her tough life, Ms Dolheguy wrote that she was not taken seriously when she told her psychiatrist she was "sick". “If only they believed me when I said I’m not sane,” she said. “I live in fear, afraid of what’s behind the corner, my heart is black. I no longer feel the emotions of happiness unless I see someone else suffer.” The 18-year-old wrote that she believed “demons are real and ghost are too, they live inside us and sometimes they win.”

“Sometimes when no one is looking, my demon comes out to play. I try and fight her but she just gets stronger.” The carer, who wishes to remain anonymous, said Ms Dolheguy’s behaviour prior to Mr Rathod's death was “extreme”. “She was extremely disturbed,” she said.

The worker believed the highly distressed and traumatised young woman would not have received adequate psychological help for her needs. She said this was due to a lack of services in the area and Ms Dolheguy’s volatile behaviour. In recent months the young woman's intensive services were largely reduced. She was free to come and go from her Sunbury home as she pleased. Another person familiar with Ms Dolheguy’s case said: “Jamie should never have been in our community and left on her own to [allegedly] harm another person. "The police, ambulance ... everyone knew the risk she posed to the community and herself, yet that risk was not taken seriously."

Loading Police have not released details about how Maulin Rathod was allegedly killed. Lovepreet Singh, a friend of Mr Rathod, said his parents had been left devastated by his violent and sudden death. "His parents are in shock," he said. "He was a very nice person. He had a jolly nature and he was a cricket lover. I loved to hang around him. He had a very humble personality and tried really hard with his studies."

When the news broke, one of Mr Rathod's childhood friends in Ahmedabad, India, told The Age the man's grieving family was in complete shock, and wanted answers about his death. "His parents ... I just can't explain their condition," said the man, who did not want his name published. "He was the only son to his parents ... And now we are raising funds to get the body back to India so we can do our religious ceremony and funeral. "Maulin was very charming and pleasing ... he would help anyone in need, if he was his friend or enemy. The man said his friend loved the Australian culture and had told his family back home he liked living in the country.

The family was now looking for answers about how he died, he said. "We must know the truth," he said. It remains unclear what services were provided to Ms Dolheguy, as a spokeswoman for the government said they could not comment on specific cases or matters before the courts. On Monday, Ms Dolheguy sat impassively with her head slightly down as she appeared before Melbourne Magistrates Court via a video link from custody.

She is charged with murder, attempted murder, intentionally causing serious injury and recklessly causing serious injury. She was remanded in custody to appear again on November 19.
