Two Men and One Woman Convicted of Conspiring to Distribute Methamphetamine

Three Marshalltown residents who conspired to distribute methamphetamine were convicted by a jury on August 16, 2016, after a five-day trial in federal court in Cedar Rapids.

Daniela Castellanos, 29, Juan Flores, a/k/a Alejandro Becerra, 28, and Marcos Perez-Trevino, 46, all from Marshalltown, Iowa, were convicted of conspiring to distribute methamphetamine.  The verdict was returned following about three hours of jury deliberations.

The evidence at trial showed that all three individuals were involved in a large conspiracy responsible for distributing multiple pounds of ice methamphetamine throughout Northern Iowa.  Flores and Perez-Trevino served as sources of supply for the organization, distributing methamphetamine in multiple ounce and pound quantities, while Castellanos was responsible for transporting and delivering methamphetamine and wiring drug proceeds to Mexico.  To date, over thirty individuals have been found guilty of conspiring to distribute methamphetamine as part of this organization.      

Sentencing before United States District Court Chief Judge Linda R. Reade will be set after a presentence report is prepared.  All three defendants remain in custody of the United States Marshal.  Perez-Trevino face a mandatory minimum sentence of ten years’ imprisonment and a possible maximum sentence of life imprisonment, over $10,000,000 in fines, $100 in special assessments, and at least five years of supervised release following any imprisonment.  Castellanos and Flores face up to twenty years imprisonment, over $1,000,000 in fines, $100 in special assessments, and at least three years of supervised release.
