An assassination attempt has been made on the life of Harry S. Truman. It was carried out by militant Puerto Rican pro- Independence activists, Oscar Collazo and Griselio Torresola while President Truman was residing at Blair House during renovations at the White House. Although the pair made it up to the entry steps at Blair House and opened fire, Torresola was killed by a Secret Service agent, Leslie Coffelt who was mortally wounded himself by gunfire. Collazo was captured and sentenced to death but Truman commuted his sentence to life imprisonment.
