Héctor Félix Miranda was assassinated by multiple shotgun blasts in 1988; two guards from the Agua Caliente Racetrack were later convicted of the murder. For the next 18 years, Blancornelas left Félix Miranda's name on the Zeta masthead, marked with a black cross. He also published a full-page ad in every issue under Félix's "byline", asking the employer of the Agua Caliente Racetrack guards, Tijuana politician Jorge Hank Rhon, why Félix Miranda had been assassinated.
