MANILA - The father of frat violence victim Dennis Venturina on Thursday said he would like his son's killers to be put back behind bars.

“I want them to suffer, pero, basta what is due them should be due them, saka dapat 'yung reclusion doblehin na, walang mga reprieve reprieve," Edgar Venturina said.

(I want them to suffer, to receive what is due them. The reclusion perpetua sentence should be doubled, with no reprieve.)

"Bakit pa hinatulan ng reclusion perpetua eh di forever, kung patagalan na lang kami mabuhay, basta mabulok sila,” Venturina added.

(Why sentence them to reclusion perpetua if it's not forever? Let's see who can outlive each other, I want them to rot.)

His son, a law student at the University of the Philippines (UP), was killed by rival fratmen on Dec. 8, 1994. A member of Sigma Rho, he was having a meal with his fratmates when they were attacked by members of rival Scintilla Juris with metal pipes and baseball bats.

The law scholar died 2 days after the attack after sustaining serious head injuries. Five Scintilla Juris members, namely Danilo Feliciano Jr., Julius Victor Medalla, Christopher Soliva, Warren Zingapan, and Robert Michael Beltran Avir were convicted of murder after 6 years of trial.

Venturina said the family only wanted to check with the Bureau of Corrections (BuCor) if the convicted murderers were given special treatment inside prison when they found out that the five had been released under the good conduct time allowance (GCTA) law.

“Parang sugat lang 'yan na naghihilom na eh nakamot uli pero ganun talaga,” Venturina said.

(It's like a wound that was just starting to heal and was scratched again, but that's how it is.)

Controversy over the GCTA law began after earlier reports that rapist-killer Antonio Sanchez might benefit from the early release grant. This was held back amid public uproar.

BuCor data, meanwhile, showed some 2,000 heinous crime convicts have been released since 2013 under the GCTA law, which was expanded to include detention time.

Authorities have also confirmed the early release of 3 convicts behind the 1997 rape-slay of sisters Jacqueline and Marijoy Chiong.

“Wake-up call na yan na (That's a wake up call that) we have to do things right,” Venturina said of the early release grants.
