Erazo-Moreno admitted that she was responsible for the distribution of at least five kilograms of methamphetamine and one kilogram of heroin during the drug-trafficking conspiracy.
She was involved in the sale of approximately 3.5 kilograms of methamphetamine and 1.2 kilograms of heroin to confidential sources and undercover law enforcement officers between February and October 2019. In addition, law enforcement officers in the Eastern District of Missouri purchased approximately 900 grams of heroin in controlled buys. Erazo-Moreno also admitted that she sold, traded, or possessed multiple firearms during these drug-trafficking activities.

Arita admitted that he was involved in the sale of methamphetamine to an undercover law enforcement officer on several occasions. Arita was arrested following a traffic stop on Sept. 5, 2018, in which officers found approximately three pounds (896 grams) of methamphetamine in his vehicle.

Perez-Martinez admitted that he is responsible for the distribution of at least 15 kilograms of methamphetamine during the conspiracy.

Perez-Martinez and Aleman-Nunez each admitted that Perez-Martinez supplied Aleman-Nunez with eight to 10 pounds of methamphetamine each week for five weeks. Perez-Martinez transported the methamphetamine from California to Missouri either by mail or by tractor trailer.

Perez-Martinez also admitted that he provided two kilograms of methamphetamine to Erazo-Moreno, who was paid to transport the methamphetamine to a customer in Columbia, Mo. The methamphetamine was seized by law enforcement officers when Erazo-Moreno was arrested during a traffic stop on Oct. 25, 2018. In total, Erazo-Moreno received more than six kilograms of methamphetamine from Perez-Martinez’s associates in Kansas City, Mo. Additionally, a law enforcement confidential informant conducted controlled drug purchases totaling 1,559 grams of methamphetamine, which were coordinated by Perez-Martinez.

Paz admitted that he is responsible for the distribution of more than 1.5 kilograms of methamphetamine during the conspiracy. Paz admitted that he sold a total of 1,314.49 grams of methamphetamine to a law enforcement confidential source from July 13 to Dec. 4, 2018.

Aleman-Nunez was arrested on April 30, 2019, when law enforcement officers were called to his residence on a disturbance. Officers searched the residence and found a stolen handgun, ammunition, approximately half an ounce of methamphetamine and drug paraphernalia.

Under the terms of their plea agreements, Lara, Erazo-Morena, Arita, Perez-Martinez, Paz and Aleman-Nunez each must forfeit to the government a money judgment according to their drug responsibility as determined by the court at sentencing, based upon drug value calculations but not to exceed $882,000, which represents the proceeds of the unlawful distribution of more than 220 pounds of methamphetamine (based on an average price of $3,500 per pound of methamphetamine) and more than two kilograms of heroin (based on an average price of $1,400 per ounce of heroin).

Under federal statutes, Erazo-Morena, Arita, and Aleman-Nunez each are subject to a mandatory minimum sentence of 15 years in federal prison without parole, up to a sentence of life in federal prison without parole.
