NSW examines institutional failures after teen found mentally ill in killing

A coronial inquest in NSW is investigating whether schools and health services overlooked warning signs before a 14-year-old killed 10-year-old Biddy Porter in July 2020. The teen, deemed not criminally responsible due to mental illness, sent texts saying she "felt crazy" hours before. Without criminal charges, the coroner's inquiry becomes the main vehicle for examining systemic gaps in adolescent mental health care.
