On the morning of April 28, 1949, Quezon left her home to travel to her husband's hometown of Baler to open the Quezon Memorial Hospital. She had been cautioned about this trip beforehand due to the frequent insurgency activities in Central Luzon of the Hukbalahap, the military arm of the Communist Party of the Philippines. She shrugged off the threat, remarking on the morning of the trip, "Supremo Taruc knows my white hair and he will not hurt me." Nonetheless, a convoy of thirteen vehicles, including two military jeeps full of armed soldiers, accompanied Quezon. Together with Quezon in her Buick sedan were her daughter "Baby", then a law student at the University of Santo Tomas, her son-in-law Felipe "Philip" Buencamino (husband of "Nini"), Quezon City mayor Ponciano Bernardo and retired Armed Forces Chief of Staff Major General Rafael Jalandoni.
