an attempt was made on the life of the Mexican President Pascual Ortiz Rubio. Modotti – who was a target of both the Mexican and Italian political police — was questioned about both crimes amidst a concerted anti-communist, anti-immigrant press campaign, that depicted "the fierce and bloody Tina Modotti" as the perpetrator (a Catholic zealot, Daniel Luis Flores, was later charged with shooting Rubio. José Magriñat was arrested for Mella's murder). As a result of the anti-communist campaign by the Mexican government, Modotti was exiled from Mexico in 1930. She first spent several months in Berlin, followed by several years in Moscow. Traveling on a restricted visa that mandated her final destination as Italy, Modotti initially stopped in Berlin and from there visited Switzerland. The Italian government made concerted efforts to extradite her as a subversive national, but with the assistance of International Red Aid activists, she evaded detention by the fascist police. She apparently intended to make her way into Italy to join the anti-fascist resistance there. In response to the deteriorating political situation in Germany and her own exhausted resources, however, she followed the advice of Vittorio Vidali and moved to Moscow in 1931. After 1931, Modotti no longer photographed. Reports of later photographs are unsubstantiated. During the next few years she engaged in various missions on behalf of the Workers International Relief organizations as a Comintern agent in Europe. When the Spanish Civil War erupted in 1936, Vidali (then known as "Comandante Carlos") and Modotti (using the pseudonym "Maria") left Moscow for Spain, where they stayed and worked until 1939. She worked with Canadian Dr. Norman Bethune during the disastrous retreat from Málaga in 1937. In 1939, following the collapse of the Republican movement in Spain, Modotti left Spain with Vidali and returned to Mexico under a pseudonym. Death In 1942, at the age of 45, Modotti died from heart failure while on her way home in a taxi from a dinner at Hannes Meyer's home in Mexico City, under what are viewed by some as suspicious circumstances. After hearing about her death, Diego Rivera suggested that Vidali had orchestrated it. Modotti may have 'known too much' about Vidali's activities in Spain, which included a rumoured 400 executions. An autopsy showed that she died of natural causes, namely congestive heart failure. Her grave is located within the vast Panteón de Dolores in Mexico City. Poet Pablo Neruda
