THE police arrested a 44-year-old suspect in Cavite during a buy-bust and found out that he was also the suspected killer of the deputy prosecutor on New Year's Eve. Philippine National Police chief Gen. Dionardo Bernardo Carlos on Sunday identified the suspect as Marvin Tagayon Linaban. He was reportedly one of the two suspects captured during a buy-bust in Barangay H2, Dasmariñas City at about 10:30 p.m. on January 7. The other suspect, Elvin Esguerra, 40, was wounded and arrested in an ensuing shootout with the arresting officers. They yielded several plastic sachets of suspected shabu with an estimated value of P69,000. Guns were also confiscated from the suspects. The police claimed Linaban admitted to his alleged participation in the shooting of Assistant City Prosecutor Edilbert Mendoza, who was exercising outside his house when gunned down in Barangay Cabuco, Trece Martires City, Cavite on New Year's Eve. 'If all evidence and facts check out, the arrest of Linaban could be a major breakthrough in the investigation of the murder of Atty. Mendoza,' Carlos said.
