Aldo Cáceres, commissioner of Bambamarca, said that the suspect is Lieutenant PNP Anderson Quispe Briones , who was drinking liquor with the victim in a bar last night, but after a few hours he took out his gun to shoot the municipal official in the chest. For the police chief, this incident was due to an apparent incorrect handling of the weapon.
