Alleged paramilitary death squad leader Roberto d'Aubuisson, who was named by a U.N. truth commission after the war's end as the mastermind of the assassination, died in 1992 having maintained his innocence to the end. Officials closed off about 2 square miles (5 square kilometers) of streets nearby to accommodate the expected crush of pilgrims, many of them bused in from the countryside, and the hundreds of vendors selling commemorative T-shirts, key chains, bags, bracelets and coffee cups for $2 to $5 as well as copies of documentaries and movies inspired by Romero's life. Authorities set up 27 giant screens for the benefit of those far from the stage and deployed 3,700 police and soldiers to provide security.
