SECURITY guard Antonio Sallas was just joking when he told street sweeper Floro Estrellado, 56, in an exclusive subdivision in Las Piñas, that he would shoot him with his shotgun. But what started out as a joke had a fatal ending for Estrellado, who was accidentally shot at close range by Sallas. Sallas immediately took the street sweeper to the hospital but the latter was pronounced dead on arrival. Sallas immediately surrendered to the police, who saw that the case was really an accident. Still, Sallas said he is willing to face the consequences in jail.
