The victims were identified as Mohamad Azri Dollah, 27, from Semariang, here, who had just completed his housemanship, and nurse Norfazillah Abdul Kadir, 23, from Kampung Baru, Samarahan.
They and two nurses from the heart centre had gone to picnic and swim at the waterfall area, about 35km from Kuching city, this morning.
At about 11am, Norfazillah was seen struggling in the water and calling out for help. Realising that she could not swim, Mohamad Azri jumped into the water to save her.
However, he too got into difficulty due to the swift current and with the frightened Norfazillah pulling at him, both went under water and disappeared.
