Four years ago on this day, Guam Police Department Sergeant Bert Piolo passed away. And the family is still asking where the justice is? In recognition of his four-year anniversary, a rally was held in Hagatna.

The sign read "Justice for Bert", and years later, family and friends continue to echo that very sentiment.

"He was born here, you know, he worked in the Government of Guam. Life matters, all we want is justice. We are not going to stop fighting for justice," said Jerelyn Piolo, Bert's mother.

On July 12, 2015, SGT Piolo at the age of 38 years old lost his life in an incident involving fellow police officer Mark Torre, Jr. Torre was arrested and charged for the murder of Piolo, and just days ago the supreme court vacated his conviction.

Jerelyn Piolo did not want to make a comment in regards to this decision, but say they will always speak up for their son and the justice he deserves.

"We felt sorry for him because he could not testify whatever happens. We really feel sorry. And he in his grave; he has no peace. It's very clear what happened - and those recordings cannot lie," she said.

Still grieving the lost, father Ely Piolo says all they want now is peace of mind.

"Right now, I feel disgusted because four years already and we don't have the justice for my son," he shared.

In commemoration of Piolo's four-year death anniversary, a justice rally was held downtown. He may be gone, but he is not forgotten.

"Waiting for mercy from God, that's what we are going to do now," said his still-grieving mother. "And just keep fighting for justice, we are not going to stop, we are not going to stop."

SGT Elbert Piolo is forever remembered by his loved ones.
