the house where the group was staying. Negrón escaped to Corozal, where he was arrested on November 10. The Nationalist Insurrection in Puerto Rico ended at Naranjito. Truman assassination attempt The revolt included the Truman assassination attempt, a failed attempt on the life of U.S. President Harry Truman, on November 1, 1950. Oscar Collazo and Griselio Torresola, from New York, carried out the attack on Blair House, where President Harry Truman was living during renovations at the White House. In the firefight between the Nationalists and police and Secret Service officers, Torresola mortally wounded a White House Police officer, who killed him in return shooting. Collazo was wounded and stood trial; convicted, he was sentenced to death, but Truman commuted his sentence to life. Truman supported the Puerto Rican effort to draft and vote on a constitution for the island's government which would establish the islands' political status. In March 1952, the people of Puerto Rico voted overwhelmingly, nearly 82%, in favor of the new constitution establishing the Commonwealth. Outcome and continued actions in 1950s Outcome of the 1950 revolts The revolts resulted in many casualties: of the 28 dead, 16 were Nationalists, 7 were police officers, 1 a National Guardsman, and 4 were civilians. Of the 49 wounded, 23 were police officers, 6 were National Guardsmen, 9 were Nationalists, and 11 were civilians. The revolt of October 1950 failed because of the overwhelming force used by the U.S.-backed Puerto Rico National Guard (the 296th Regiment of the United States National Guard), the FBI, the CIA, and the Puerto Rican Insular Police, all of whom were aligned against the Nationalists. Dozens of Nationalists were killed and wounded, and hundreds of others were arrested and held in prison. The U.S.-backed Puerto Rico National Guard had also bombed the towns of Jayuya and Utuado. Critics have said that there was not sufficient coverage of the suppression of the uprisings. According to an anonymous and undated article in the New York Latino Journal in the early 2000s, it was described at the time in the mainland press as an "incident between Puerto Ricans." After the assassination attempt against him in 1950, Truman pushed for a "status referendum" and accompanying "constitution." In a March 1952 vote, nearly 82% of voters in Puerto Rico approved the constitution. This result was controversial, since the referendum had only offered a choice between the existing colony or commonwealth,
