On November 1, 1950, Puerto Rican nationalists from New York City, Griselio Torresola and Oscar Collazo, attempted to assassinate President Harry S. Truman at his temporary residence of Blair House. Torresola was killed during the attack, but Collazo was wounded and captured. He was convicted of murder and sentenced to death, but President Truman commuted his sentence to life. After Collazo served 29 years in a federal prison, President Jimmy Carter commuted his sentence to time served and he was released in 1979.
