TUGUEGARAO CITY -- The 39-year-old vice mayor of Pamplona town in Cagayan was shot dead by two motorcycle-riding gunmen at about 11:20 p.m. Friday at the house of a close friend, police said.

Vice Mayor Aaron Sampaga was gunned down with an M-16 Armalite rifle and a Cal. 45 handgun by two men, who wore black jackets, blue shirts and caps, Pamplona town police chief, Senior Insp. Francis Pattad, said.

Pattad said the gunmen rode through the river control makeshift road to enter the compound of Sampaga's close friend, Rodolfo Guzman, and fired at Sampaga.

Guzman and their companions were unhurt.

Pattad and his men found six empty shells of an M-16 Armalite rifle and two .45 slugs at the shooting scene.

Sampaga was a three-term town mayor before he ran and won as vice mayor during the May 9 elections.

His sister, Arnie Angelica Sampaga, won as mayor against former vice mayor Edwin Ifurung. (PNA)
