whom died before their spouses were elected president.) It was widely believed that the Hukbalahap was responsible for the killings. In preparation of the attack, the insurgents had blockaded the road and rounded up passengers from passing vehicles, and one of those passengers claimed seeing a former employee of his who had joined the Huk as among the armed men. While General Jalandoni, who survived the attack, tagged the Huks as responsible, the chief of the Philippine Constabulary laid blame instead on bandits. President Quirino blamed the Huks and responded by calling for "a people's war on the dissidents". Luis Taruc, supremo of the Hukbalahap, denied that his group was responsible for the crime, though he also claimed that the Huk were conducting an investigation of their own if one of the group had breached ranks and participated in the killing. Nonetheless, after Taruc's surrender in 1954, he was formally charged for the murder of Quezon and other members of her party; these charges would be dropped before they could be heard on trial. Throughout the 1950s, several other captured Huk members would be charged for participation in the assassination, with five of them being sentenced to death by a Cabanatuan trial court. Luis Taruc later wrote the killings were discussed as an agenda item at the December 1949 to January 1950 Politburo meeting, "the accidental killing in a Huk ambush of Mrs. Quezon, widow of the late President Quezon, and her daughter. The majority took a characteristic Communist attitude toward this deplorable event. The victims had been 'class enemies', and that settled everything." On April 28, 2005, exactly fifty-six years after her death, the remains of Quezon were transferred from North Cemetery for interment in a black crypt beside her husband's sarcophagus at the Quezon Memorial Shrine in Quezon City. The re-interment rites were attended by President Gloria Macapagal Arroyo and the Quezons' sole surviving child, Zenaida "Nini" Quezon-Avanceña. Legacy The Manila Provincial Road that traverses from Quezon City to Manila was renamed Aurora Boulevard in her honor in 1951. In the same year, Elpidio Quirino created the Aurora sub-province comprising Baler and surrounding areas in the adjacent Quezon Province. In 1978, Aurora became a separate province. Manuel and Aurora Quezon are the only spouses to have respective provinces in the Philippines named after them. The first major building erected on Aurora Boulevard (also called Aurora Avenue), that is,
