CEDAR RAPIDS — Three Marshalltown residents, who participated in a large scale methamphetamine ring throughout Northern Iowa, were convicted by a jury last week in federal court.

The jury found Daniela Castellanos, 29, Juan Flores, also known as Alejandro Becerra, 28, and Marcos Perez-Trevino, 46, guilty of conspiring to distribute methamphetamine after deliberating about three hours. The five day trial started August 8 in U.S. District Court.

The evidence at trial, which included wiretapping recordings and statements made by other co-conspirators, showed that all three were involved in the expansive conspiracy responsible for distributing multiple pounds of ice methamphetamine beginning in the spring of 2013 throughout Northern Iowa.

Flores and Perez-Trevino served as sources of supply for the operation, distributing methamphetamine in multiple ounce and pound quantities, while Castellanos was responsible for transporting and delivering meth and wiring drug proceeds to Mexico.

Court documents show Perez-Trevino was involved in distributing at least, 500 grams of a mixture and substance containing meth and 50 grams of pure meth.

As of this week, over 30 individuals have been found guilty of conspiring to distribute methamphetamine as part of this operation, according to the U.S Attorney’s Office.

Mario Murillo Mora, another co-conspirator who was sentenced Monday, received ice methamphetamine, which was brought into Iowa, concealed in passenger vehicles, and he typically received the product in multiple pound quantities, court documents show. Evidence shows in one transaction that he received in Marshalltown, he re-packaged the ice meth into smaller quantities and distributed it to a network of upper level distributors, typically in half- and one-pound quantities.

Murillo Mora also relied on other sources to transport and distribute the meth, documents show. Castellanos assisted Murillo Mora in transporting meth to Murillo Mora’s customers, collected money from them and then wired drug proceeds to Mexico on his behalf.

Becerra, who’s real identity is Juan Flores, and Perez-Trevino were two of Murillo Mora’s alternative sources for supply of ice meth to his “upper level” customers, court documents show. Becerra conducted some of his drug transactions at the Isle of Capri Casino in Waterloo.

And Perez-Trevino also purchased ice meth from Murillo Mora’s upper level customers when he couldn’t get it from other sources, according to court documents.

Murillo Mora pleaded guilty in February and was sentenced Monday to 21 years in federal prison for conspiracy of distribution of methamphetamine and conspiracy to commit money laundering.

Perez-Trevino faces a mandatory minimum of 10 years and possibly up to life in prison. He also faces a fine of up to $10 million.

Castellanos and Flores each face up to 20 years in prison and over $1 million in fines.
