A court in Suva, Fiji's capital, found Bimlesh Dayal, 43, guilty of the murder of his wife Ranjini Rekha Singh and their two minor daughters, Amisha and Anisha, on the intervening night between Oct 28-29, 2011, media reported.
Dayal had claimed that his wife had an affair with their landlord's son.
He also claimed that he had seen his wife standing by the bed with a chopper in hand with blood dripping all over.
However, the court found evidence that Dayal had indeed killed all three of them.
Sentencing has been set for April 30.
