In a chance interview on Thursday, Justice Secretary Vitaliano Aguirre II said the Digos City Prosecutor's Office found probable cause against Matobato, who is accused of shooting complainant Abeto Salcedo Jr. in October 2014.
Aguirre could not say if the case has been filed at the Digos City Regional Trial Court.
"Tapos na ang resolution ng complaint kaya anytime pwede mafile na," he said in a text message.
Salcedo alleged that Matobato shot him several times as he was leaving the Department of Agriculture (DAR) office in Digos City where he once worked as adjudicator for DAR-Southern Mindanao.
The former government employee surmised the attempt on his life was related to his work as DAR adjudicator.
Matobato denied the charges, telling a Senate inquiry last October that he was under the DOJ's Witness Protection Program when the incident took place.
Matobato claimed he killed several individuals on President Rodrigo Duterte’s orders during the latter’s term as city mayor of Davao. Malacañang has since denied Matobato's allegation.
Matobato was admitted to the WPP during the term of then-justice secretary and now Senator Leila De Lima, but left when Duterte won the presidency in May last year.
