BULLET shells recovered from the house of slain broadcaster Juan 'Johnny Walker' Jumalon match with the gun used by a suspect in the killing of an engineer last month, leading to speculations that the hit men in both slayings in Calamba, Misamis Occidental, could be a member of the group that shot the radioman.

Philippine National Police (PNP) Public Affairs Office chief Col. Jean Fajardo said Sunday that the suspect in the killing of the municipal engineer was arrested in an anti-drug operation in Barangay Don Bernardo Neri in Calamba town last Tuesday.
