ANOTHER suspect in the murder of actress Cherry Pie Picache’s mother surrended to the National Bureau of Investigation on Thursday. Sherwin Ledesma, however, denied the accusation of Michael Flores that he killed Zenaida Sison, 75, in her house in Quezon City on Sept. 19. Flores, a stay-out house helper of Sison, denied he participated in the killing of Picache’s mother. He was arrested in Laguna province on Tuesday. Robbery is being eyed as the motive of the crime after some P500,000 worth of cash and jewelry were reportedly missing from Sison’s house. Meanwhile, Picache expressed satisfaction after learning of Ledesma’s surrender saying “it is just the beginning. We want conviction”.
