Two shop workers were stabbed to death as they ate lunch in the back room of a Takanini pawn shop.
They did nothing to bring it on themselves, a jury in the High Court in Auckland was told.
"They didn't see it coming. The whole thing took three minutes," prosecutor Karen Chang told the High Court today.
Zarn Tarapata, 25, is charged with murdering pawn shop owner, Paul Fanning, 69, and an employee, Paul Matthews, 47, at Ezy Cash loan store on Great South Rd, Takanini, on July 19 last year.
He has admitted killing them but pleaded not guilty on the basis that he was legally insane at the time.
