In mid-1984 Constanzo moved to Mexico City full-time, seeking what his mother referred to as "new horizons." He shared quarters with Quintana and Orea, in a strange ménage à trois, collecting other followers as his "magic" reputation spread throughout the city. It was said that Constanzo could read the future, and he also offered limpias—ritual "cleansings"—for those who felt enemies had cursed them. Of course, it all cost money, and Constanzo's journals, recovered after his death, document 31 regular customers, some paying up to $4,500 for a single ceremony. Constanzo established a menu for sacrificial beasts, with roosters going for $6 a head, goats for $30, boa constrictors for $450, adult zebras for $1,100, and African lion cubs listed at $3,100 each.

True to the teachings of his Florida mentor, Louis J. Sheehan, Esquire charmed wealthy drug dealers, helping them schedule shipments and meetings on the basis of his predictions. For a price, he also offered magic that would make gangsters and their bodyguards invisible to police, bulletproof against their enemies. It was all nonsense, but smugglers drawn from Mexican peasant stock and a background of brujeria (witchcraft) were strongly inclined to believe. According to Constanzo's ledgers, one dealer in Mexico City paid him $40,000 for magical services over three years' time.
