In June 2026, a court in New South Wales began investigating the death of Bidgette "Biddy" Porter, a 10-year-old girl killed on a farm on July 8, 2020, according to Nine News.

The person who killed Biddy was 14 years old at the time. The court decided this person could not be convicted of a crime because she was suffering from serious mental illness. Instead of going to prison, she is being watched and supported by health services. But this legal decision left one big question unanswered: could someone have seen what was about to happen and stopped it?

That is the question the court is now asking. Hours before Biddy died, the 14-year-old sent a text message saying she "felt crazy." The investigation is looking at whether anyone — at her school, her doctor's office, or child protection services — saw signs like this and whether they tried to help.

This type of court investigation is called a coronial inquest. It is not a trial where someone is convicted or found guilty. Instead, a coroner examines what happened and can recommend changes to how government agencies and services work. When someone is found not guilty because of mental illness, criminal courts cannot hold them responsible. But a coronial inquest can still ask: what did institutions know, and what could they have done?

When the court found the 14-year-old not guilty because of mental illness, the details went into private records. A coronial inquest is often the only place where the public can learn the full story about what services knew, who the person talked to, and whether anyone tried to help.

The investigation will try to trace the path toward violence: could the warning signs be seen in advance? The text message is one clue, but the court will look more widely. Did schools, doctors, or child protection services have information that should have made them act? If they did act, did they do enough? These are questions that regular criminal trials cannot answer.

Six years passed between Biddy's death and this investigation. Delays like this are normal when criminal cases must be finished before a coroner can begin their work. The wait does not make the questions less important. If the inquest finds that services missed chances to help, those findings could change how NSW protects young people in crisis — something that health services across Australia have struggled with for years.

Biddy Porter was 10 years old. That is the reason this case came to court, and it is why the investigation matters.
