Her family said they fear the case may go on unresolved for years, as it has already been nearly four years since the crime was committed.
“Apple,” as the victim was fondly called, was found dead a few meters from their residence in Sitio San Roque in Barangay Bascaran, Daraga.
Her body bore signs that she was hit by a hard object and strangled.
Various groups, including activist organization Gabriela-Bicol, have since condemned the incident.
The Criminal Investigation and Detection Group (CIDG), which is handling the case, said it is waiting for a suspect to surrender, as only circumstancial evidence is available at present.
