Mangaldan re-electionist Councilor Freddie Muyano Soriano passed away last Sunday.
The source said he felt dizzy and became unconscious when he was on a campaign sortie at Barangay Banaoang at around 10 pm last Friday.
Friends rushed him to Nazareth Hospital in Dagupan City where he was confined for two days before he expired Sunday afternoon.
Before becoming a member of the Sangguniang Bayan, the older Soriano was a 12- year village chief of Barangay Guilig of the town and served as councilor before his demise.
Source said his son Aldrin, a local ABS-CBN TV reporter, will succeed him as candidate for the town council under the Liberal Party's ticket of re-elective Mayor Bona Fe Parayno.
