The first attempt on Trotsky’s life, in his house at Coyoacán, left more than seventy scars in the plaster of the bedroom walls. At 4am on May 24, 1940, a heavily armed group led by painter David Siqueiros (who had been a commander in the Spanish Civil War and was working under the orders of the Stalinist Mexican Communist Party) overcame the guards and pumped more than two hundred shots into the house. Trotsky, his wife and son survived only by hiding under their beds. After this, the house, already heavily guarded, was further fortified. Unknown to all, though, the eventual assassin had already inveigled his way into the household, posing as a businessman being converted to the cause. Although he was never fully trusted, his arrival at the house on the afternoon of August 20, with an article that he wanted Trotsky to look over, seemed innocuous enough. Trotsky invited him into the study and moments later the notorious ice pick (the blunt end), which had been concealed under the killer’s coat, smashed into Trotsky’s skull. He died some 24 hours later, in the hospital after an operation failed to save his life. The killer, who called himself Frank Jackson and claimed to be Belgian, served twenty years in jail, though he never explained his actions or even confessed to his true identity, Jaime Ramón Mercader del Río.
