Transgender killer jailed for murdering parents before converting to Islam

She had begged to skip the sentencing, expressing fears that confronting the details of her crimes might trigger a psychological collapse, but Judge Barnes refused the request.

Ryan Stout, defending Bailey, read a statement on her behalf in which she declared: "It brings me great pain and regret I was not in a stable mindset at the time, and if only I had gotten help, this would have been preventable.

"Because of my religious beliefs as a Muslim, it would be appropriate to take my life for atonement for what I did."

Bailey entered her parents' home on June 18 2024 with the stated intention of killing them, according to court documents.

Her mother sustained four gunshot wounds while her father was shot twice in the head.

Following the shootings, Bailey descended to a lower floor and fired through a closed bedroom door towards her brother, who had barricaded himself inside with his wife.

The couple escaped to a neighbouring property and contacted emergency services.

The brother and his wife reported hearing their parents shout at Bailey to leave before gunshots rang out, according to police documents.

Bailey fled the scene but was apprehended 16 hours later in St George after an extensive search.

Upon arrest, she told officers she had arrived at the property "with the intent to kill her parents" and expressed no remorse, stating: "I would do it again. I hate them."

The 30-year-old killer had previously been diagnosed with a range of psychiatric conditions including schizophrenia, autism, ADHD, OCD, anxiety, depression, and possible bipolar disorder with psychosis.

Her lawyer noted she had no prior criminal record and had legally changed her name and gender approximately a year before the killings.

Mr Stout argued the murders stemmed from "severe psychiatric dysfunction, not calculated evil," describing how autism, schizophrenia and hormonal destabilisation combined to create "a perfect storm".

Her brother Dustin claimed that hormone treatment administered during a mental health crisis had contributed to the tragedy.

"Providing powerful hormones to a person in a psychiatric crisis without proper psychiatric safeguards is not affirming care. It is reckless," he told the court, adding: "We support LGBTQ rights fully. This has nothing to do with identity."

Bailey had discharged herself from hospital just ten days before the murders.

Both surviving brothers delivered emotional statements to the court about the devastation wrought upon their family.

Cory Bailey told the judge that keeping his sister imprisoned indefinitely represented the best outcome for everyone involved. "We've lost our parents, and we've lost a sibling in many ways as well. So either way, no matter what, we are losing as a family on this sentence," he said.

Dustin Bailey spoke directly about their mother's tireless efforts to support her daughter through mental health struggles. "When Mia struggled, Gail's response was not frustration or withdrawal. It was persistence," he said.

He described missing their mother's prize-winning pies and their father's steadying presence around the home.

The brothers backed consecutive sentences, arguing each parent's life deserved individual recognition, whilst opposing life without parole.
