Andi Guerrero-Lara, Methamphetamine Trafficking, Massachusetts 2022

A Methuen man has been sentenced in federal court in Boston for selling a fentanyl and acetyl fentanyl mixture to an undercover agent on five occasions.

Andi Guerrero-Lara, a/k/a ‘Manny Sierra,’ 25, was sentenced on September 28, 2022 by U.S. District Court Judge Richard G. Stearns to seven years in prison and four years of supervised release.

In December 2019, Guerrero-Lara was indicted along with co-defendant Angel Rivera-Valle. He was subsequently charged in a superseding indictment on September 2, 2020.

The defendants were members of a drug trafficking organization operating in the Merrimack Valley area of Massachusetts that regularly sold large quantities of fentanyl. Between September and October 2019, an undercover agent purchased a fentanyl and acetyl fentanyl mixture from the defendants on five separate dates.

After Rivera-Valle was arrested, Guerrero-Lara led agents on a high-speed car chase in 2019 that spanned numerous miles and three cities during which Guerrero-Lara endangered multiple lives, as he narrowly missed crashing into a construction zone and police vehicles.

Guerrero-Lara was arrested after stopping his vehicle at an apartment complex in Lawrence.

“Drug traffickers like Mr. Guerrero-Lara are a danger to our communities. This individual pumped deadly opioids into our neighborhoods and, when he was finally exposed, recklessly endangered multiple lives in lengthy, a high-speed car chase,” said United States Attorney Rachael S. Rollins.

This case is part of a coordinated enforcement operation in the Merrimack Valley called ‘Devil’s Highway.’ The operation targeted the distribution of opioids, including fentanyl and heroin and resulted in charges against a total of 40 people for federal drug offenses, with at least a dozen more individuals facing state charges.

Andi Guerrero-Lara, also known as Manny Sierra, was convicted of one count of conspiracy to distribute 400 grams or more of fentanyl and 100 grams or more of acetyl fentanyl; three counts of distribution and possession with intent to distribute 40 grams or more of fentanyl and 10 grams or more of acetyl fentanyl; two counts of distribution and possession with intent to distribute 10 grams or more of acetyl fentanyl and fentanyl; and one count of possession with intent to distribute 100 grams or more of acetyl fentanyl and 40 grams or more of fentanyl.
