Sitiveni ‘Esi Muli, 17, was found guilty of the murder of Feng Sheng Pei and his wife Su Jie Wen.
A seven-member jury found Muli guilty on two counts of murder and one count of armed robbery on Thursday.
Kaniva News reports the jury took about less than an hour to reach its verdict.
The court previously heard how a disagreement over a payment led to Muli attacking Feng before he attacked Su.
The couple’s bodies were found with multiple stab wounds on their heads and necks at their vegetable plantation.
