Overview
- NSW Supreme Court Justice Ian Harrison imposed three life terms with no parole, calling the crimes "senselessly cruel and cynical."
- Kwang Kyung Yoo strangled Min Kyung Cho and a seven-year-old at his North Parramatta studio, then drove her BMW to Baulkham Hills and fatally stabbed Hyun Soo "Steven" Cho.
- Sentencing remarks cited premeditation, including multiple checks of the victims’ premises and Yoo telling his wife a BMW would arrive that day.
- The court heard Yoo fabricated elite achievements and wealth while carrying significant debts, behavior a forensic psychologist described as "grandiose fantasy."
- Yoo pleaded guilty and wrote a letter expressing remorse, though the judge concluded his culpability remained undiminished.
