An illegal immigrant has copped to being a fentanyl delivery boy for another man accused of pushing tens of thousands of pressed fentanyl pills in the Boston area.

Freddy Artemio Guerrero Soto, 29, a national of the Dominican Republic, pleaded guilty to conspiracy to distribute and possess with intent to distribute 400 grams or more of fentanyl and possession with intent to distribute 400 grams or more of fentanyl.

The charges carry a minimum prison term of 10 years — and up to life — in prison as well as a fine of up to $10 million. He’s scheduled for sentencing in federal court in Boston on May 12.

Guerrero Soto was charged a day after his alleged boss, Anderson Ernesto Andujar Echavarria and two others, Waner Bernabel Presinal and Carlos Fabal, were charged with pushing the deadly fentanyl drug in and around Boston. Soto originally pleaded not guilty at his arraignment, like his co-defendants, before changing his plea on Wednesday. The cases against the others are ongoing.

Undercover federal law enforcement officers built their case against the men by setting up fentanyl purchases with Andujar. Law enforcement filed a federal complaint against Andujar on Sept. 12, 2024, but continued their case against him the next day before the complaint was public.

That day, according to a law enforcement affidavit, an undercover agent set up a buy with their principal target for 30,000 pressed fentanyl pills and 500 grams of powder fentanyl. They were to meet in a hotel parking lot near the South Bay shopping center in Boston for the handoff.

Andujar, however, allegedly pulled over in a nearby car wash parking lot and, the feds say, Guerrero Soto drove up in his scooter and picked up the drugs. He was to be the runner. The feds say he then scooted on over to the location and made the handoff.

Agents arrested Guerrero Soto right after and, according to an affidavit, found a Dominican identification card on him. The baggies of drugs, 15 bags of pressed blue pills and five bags of light brown powder, contained more than two kilograms of fentanyl.
