DAGUPAN CITY (PHILIPPINE DAILY INQUIERER/ASIA NEWS NETWORK)- A farmer on Friday (Oct 27) killed his wife and her alleged lover before killing himself in Mangatarem town in Pangasinan province, police said.

Mrs Margie Doque and her supposed lover Eduardo Sacopia were caught in bed by her husband, Roberto Doque, on the second floor of his mother-in-law's house in Casilagan village at 7.58pm, police said.

Investigator PO1 Jessie Macaraeg said an enraged Roberto then hacked his wife and Sacopia with a bolo (large cutting tool similar to a machete).

Roberto then went home where he drank a bottle of pesticide. He was taken to a hospital but died while undergoing treatment.

Mr Sacopia was already dead when investigators arrived at the scene. Mrs Doque was taken to a hospital but succumbed to her injuries.

The investigator said the Doque couple had two adult children, one of whom was watching a basketball match at the time of the attacks. The other child worked in Manila.

Investigators recovered from the Doque house a 49cm- long bolo and a bottle of pesticide.
