Their most serious violation involved the abduction of Martin "Baldo" Chupchupen, a resident of Mainit, Bontoc, Mountain Province. Chupchupen had come from Mainit to buy a carabao in Alangtin and thus didn't know that there was an ongoing military operation.
Pinakamalala nilang paglabag ang pagdukot kay Martin 'Baldo' Chupchupen na taga-Mainit, Bontoc, Mountain Province. Galing si Chupchupen sa Mainit para bumili ng kalabaw sa Alangtin kaya hindi niya alam na may operasyon ang militar.
