Springfield Gang Indicted in Massive Cocaine Ring

SPRINGFIELD, Mo. – Three southwest Missouri residents are among five defendants indicted for their roles in a drug-trafficking conspiracy after federal agents seized 16 kilograms of cocaine while arresting two co-defendants in Texas.

Mario Jose Castillo, 55, of Springfield; Christhian Eduardo Cruz-Pineda, 22; Johnathan David Emerson, 47, both from Willard; and Bryan Ramirez-Aguero, 33, and Erika Martinez Hernandez, 40, both residents of Grand Prairie, Texas, were charged in a 10-count superseding indictment returned by a federal grand jury in Springfield.

Today’s superseding indictment replaces an earlier one from April 10, 2024. It contains the same or similar charges but increases the amount of cocaine and extends the conspiracy timeframe to include another drug seizure.

Federal agents arrested Ramirez-Aguero and Martinez Hernandez on April 11, 2024. They seized approximately 16 kilograms of cocaine and $145,123 from their residence at the time of their arrest.

The indictment alleges all five defendants participated in a conspiracy to distribute cocaine from December 12, 2021, to April 11, 2024. Castillo faces additional charges including being a felon in possession of a firearm and money laundering.

This case is part of an Organized Crime Drug Enforcement Task Forces (OCDETF) operation, which identifies, disrupts, and dismantles the highest-level criminal organizations. Additional information about OCDETF can be found at https://www.justice.gov/OCDETF.
