In July 1936, during the Spanish Civil War, Br. Jaime was imprisoned at Mollerosa in Zaragoza, Spain for being a religious. In December of the same year, he was transferred to Tarragona and was then confined on a prison ship. On January 15, 1937, he was convicted of being a Christian brother. On January 18, Br. Jaime was shot to death at the Mount of Olives cemetery near Tarragona. Since the soldiers were ordered by their commander to shoot wide, their two volleys did not kill Br. Jaime; he was murdered when the commander shot him five times at close range. Br. Jaime was the first of the 97 Lasallian Brothers who had died in Catalonia during the Spanish Civil War to be recognized as a martyr.
