On this date in 1950, two assassins made an attempt on the life of President Harry Truman. The attempt was made when Truman was staying in Blair House while structural repairs were being made to the White House.
Oscar Collazo and Griselio Torresola, members of the pro-independence Puerto Rican Nationalist Party, approached Blair House from opposite directions. They planned to mount simultaneous assaults and shoot their way inside the house, where they would kill Truman. The men engaged White House police officers and Secret Service agents in a gun battle that resulted in the wounding off two officers and the death of Officer Leslie Coffelt.
Neither assassin gained entry to Blair House. Torresola was killed by Officer Coffelt before he collapsed and died from his own wounds. Collazo (pictured above) was wounded in the gun battle and arrested. He was tried, convicted, and sentenced to death. His sentence was commuted to life by President Truman. He was pardoned by President Jimmy Carter in 1979. He returned to Puerto Rico, where he died in 1994 at the age of 80.
