Overview
- NSW Supreme Court Justice Ian Harrison imposed three life sentences without parole, calling the murders “senselessly cruel” and “without a trace of human compassion.”
- Yoo pleaded guilty to killing a woman and a seven-year-old at his North Parramatta studio, then driving the woman’s BMW to Baulkham Hills and fatally stabbing her husband.
- The court accepted that Yoo planned the crimes, with the judge saying he acted on an irrational belief tied to obtaining the woman’s vehicle.
- Evidence detailed Yoo’s fabricated persona—including false claims about Olympic selection and luxury assets—contrasted with significant debts and a psychologist’s description of “grandiose fantasy.”
- Relatives delivered harrowing victim impact statements, and Yoo submitted a written apology expressing remorse and religious reflection, which the judge said did not lessen his moral culpability.
