Superintendent Romeo Caranza, Tayabas police chief, identified the fatalities as Norma Labado and her children Jerymiah, 8; Jaypee, 6; and Ira, 3.
Police said Labados husband Godofredo reported the incident after finding his wife and three children dead inside their house in Barangay Ilayang Ilasan, about 15 to 20 kilometers from the town proper.
Caranza said Labado could have snapped out of her right mind and committed the crime.
"But we are still investigating other angles in this case," he added. Arnell Ozaeta
