It might be fair to say that it’s “crazy, but that’s how it goes,” after the Bay State’s Attorney General announced the fruits of an 11-month investigation dubbed “Operation Crazy Train.”

The Thursday announcement isn’t some anecdote captured from a relaunch of The Osbournes, but is the product of cooperation between the Massachusetts State Police’s Commonwealth Interstate Narcotics Reduction and Enforcement Team and the Drug Enforcement Agency’s Cross Border Initiative — nearly a year’s worth of which “resulted in the execution of search warrants at 15 locations in Methuen and Lawrence” and the arrest of 11 people.

“During the takedown, troopers, officers, and agents seized approximately 2.5 kilograms of fentanyl, 193 grams of cocaine, 225 grams of methamphetamine, 206 grams of pills, 30 grams of crack cocaine, two large-capacity firearms, and one magazine containing 15 rounds of ammunition, as well as additional ammunition,” Attorney General Andrea Campbell’s office said in a release.

According to the AG’s office, beginning in May investigators were court-authorized to intercept the communications of “seven target individuals’ cellphones via wiretap.” After four months of listening, the AG’s office says they were led to the person allegedly supplying drugs to the originally targeted “initial drug trafficking organization,” a Lawrence man named Yasil DeLossantos.

“The AGO and MSP were granted authorization to wiretap the cell phones of DeLossantos and three other individuals. All of these individuals, including DeLossantos, were confirmed to have supplied narcotics to other drug trafficking operations with their own customer base,” the AG’s office said in their release.

The investigation, according to the AG’s office, required authorization for “well over” 100 search warrants. The evidence obtained through wiretaps, “controlled” drug purchases, camera surveillance, cell phone and vehicle GPS tracking, on Wednesday morning culminated in the search of more than a dozen locations in Methuen and Lawrence and warrants for a dozen suspects.

“The execution of those search warrants took place simultaneously with more than 200 members of law enforcement from MSP, DEA, and local police departments in Massachusetts and New Hampshire,” the AG’s office said.

Identified by the AG as facing a litany of charges, from weapons related offenses to trafficking in fentanyl or cocaine, are Methuen residents Alexander Franco Melo, 23; Edwin Arias Melo, 24; Lauris Mercado Victoria, 29; Cristian Gonzalez Cosme, 50; Angel Franco Romero, 48; Luis Arias Mateo, 30; as well as Lawrence residents DeLossantos, 33; Angel Luis Medina Melo, 31; Santo Marte-Aybar, 34; Franklin Avalo, 34; and Julio Baez, 32.

A twelfth man, Guerin Lara Vizcaino, 25, of Lawrence, was not apprehended but is wanted by authorities, the AG’s office said.

All of the accused are scheduled to appear in Lawrence District Court on November 4 for probable cause hearings.
