An initial investigation into the incident has determined that the NPA fighters were taken into custody after being overpowered by the operating troops of the AFP. However, instead of treating them as as prisoners-of-war, the NPA fighters were mercilessly tortured and killed by their fascist captors.
Sa inisyal na imbestigasyon sa insidente, natukoy na nabihag ang mga Pulang mandirima matapos silang magapi ng mga nag-ooperasyong tropa ng AFP. Subalit sa halip na tratuhin silang mga bihag-sa-digma, walang awang tinortyur at pinatay ang mga Pulang mandirigma ng mga pasistang dumakip sa kanila.
