Overview

Case overview

On August 21, 1983, on the apron of what was then Manila International Airport, Benigno "Ninoy" Aquino Jr., a former Philippine senator, was assassinated with a gunshot to the head. An investigation instigated by Marcos shortly after the assassination resulted in 25 military personnel and one civilian being charged with murder; all were acquitted by the Sandiganbayan (special court). [1]

An investigation instigated by Marcos shortly after the assassination resulted in 25 military personnel and one civilian being charged with murder; all were acquitted by the Sandiganbayan (special court). A second investigation, during the presidency of Corazon Aquino, led to a retrial of 16 military personnel, all of whom were convicted and sentenced to life imprisonment by the Sandiganbayan. In 1972, shortly after martial law was declared by Marcos, he was imprisoned on falsified charges; he was only released in 1980, when he had a heart attack. [2]
