The suspects, Eleora Robion Salvaloza, 36, and her son, Eleocel, 18, are now detained at the Pilar town jail.
Police said Eleora and her husband, Celso Escatron Salvaloza, had a verbal tussle over family problems that ended in a scuffle.
Eleora shouted for help and her son came to her rescue, wielding a piece of wood with which he and his mother alternately struck Celso on the head, killing him on the spot. — Ben Serrano
