Oscar Collazo

Oscar Collazo (January 20, 1914 – February 21, 1994) was a Puerto Rican militant of the Nationalist Party. He and Griselio Torresola were responsible for the attempted assassination of U.S. President Harry S. Truman in Washington, D.C. on November 1, 1950. He had been living in New York City after growing up in Puerto Rico.

Collazo was convicted and sentenced to death, but Truman commuted his sentence to life imprisonment. In 1979, Collazo's sentence was further commuted to time served by President Jimmy Carter. He was paroled and allowed to return to Puerto Rico.
