It was members of the military escort that killed Ninoy.
Originally the murder was blamed on some criminal (Rolando Galman) whose bullet riddled corpse was left on the tarmac for all to see.
The only problem was that even though he was shot many times there was little or no blood. This indicates that the body was already dead when it was riddled.
The assassination was ordered by Danding Cojuangco, a relative of Ninoy as confessed by the assassin Pablo Martinez.
Evidently Ferdinand was livid when he heard of the incident.
edit
Rolando Galman, as stated by another answer, was already dead before Ninoy was murdered.
FYI
The military escorts were all jailed but have since been pardoned and released.
Ninoy Aquino and Jose Rizal were both Filipino nationalists who fought for independence and democracy in the Philippines. They were both advocates for social justice, education, and the welfare of their fellow Filipinos. Rizal is known for his writings that inspired the revolution against Spanish colonization, while Ninoy was a prominent opposition leader against the Marcos regime.
Former Philippine Senator Benigno "Ninoy" Aquino famously said, "The Filipino is worth dying for," expressing his dedication to the Filipino people's welfare and freedom. He was assassinated in 1983 but is commemorated for his courage and love for his country.
Rizal and Ninoy AquinoNinoy Aquino said: "The Filipino is worth dying for." Well, Ninoy is a hero today. Filipinos had him killed. Imagine Jose Rizal having said too: "The Catholics are worth dying for." Rizal today would be a saint. The Catholics had him killed. And this is exactly how sick we all are today as the Sick Man of Asia. Thanks to Filipino catholic theologians, like Father Jose S. Arcilla, S.J., and his ilk who have not ceased writing brazen lies and other sacred falsehoods about Jose Rizal's soul saved in heaven. What a crock of religious hypocrisy! Poch Suzara
Both Jose Rizal and Ninoy Aquino were Filipino nationalists who fought against oppression and injustice. They both advocated for democracy and freedom for the Filipino people, challenging the ruling powers of their time. Additionally, both men were willing to sacrifice their lives in pursuit of their beliefs, with Rizal executed by the Spanish colonial authorities and Ninoy assassinated during the Marcos dictatorship.
