Another child, Kha Xing Ruu, 15, was admitted in critical condition to the Raja Perempuan Zainab II Hospital.

Deputy Kelantan police chief SAC Din Ahmad believed the incident took place at about 1.30pm.
“Initial investigations show that all victims were attacked one at a time.
“Police also believe that revenge is the motive behind the killings.
“There was no sign of a break-in and the couple still had their valuables on them,” he said.

Din said the assailant is believed to have escaped in Kha’s van and police were looking for the vehicle.
