A North Shore drug dealer who was busted for one of the largest seizures of fentanyl in the region, including distributing heart-shaped pink pills that looked like candy, has pleaded guilty.

Lynn man Deiby Felix, 41, has been tied to a large-scale drug trafficking organization on the North Shore.

He pleaded guilty in Boston federal court on Monday after millions of doses of fentanyl and meth — with a street value of more then $8 million — were seized from the organization’s stash location and lab.

Police in July of 2023 were investigating an overdose death in Salem, which led investigators to the drug trafficking organization led by Felix and others.

Then agents conducted searches at four locations in Lynn, resulting in one of the largest single-location seizures of fentanyl and meth in Massachusetts and the region.

“The seizure included nine kilograms (20 pounds) of pink heart shaped fentanyl-laced pills pressed to look like candy,” the U.S. Attorney’s Office said in a statement. “Additional narcotics and five firearms were also seized.

“During the course of the investigation over 75 kilograms (198 pounds) of fentanyl and methamphetamine was seized, along with multiple additional kilograms of cocaine and dozens of kilograms of cutting agents, including xylazine, that is used to adulterate controlled substances,” the office added.

In total, an estimated eight million individual doses of fentanyl and meth laced pills and powder were seized. The street value is believed to be upwards of $8 million.

Agents searched Felix’s residence and found more than three kilograms (6.6 pounds) of pressed pills containing meth and fentanyl, along with a gun.

A later search of the residence also revealed a clandestine drug lab that had been built into a small room in the basement. Multiple industrial pill presses, mixing equipment and other manufacturing paraphernalia and equipment were also recovered.

Felix pleaded guilty to one count of possession with intent to manufacture and distribute 400 grams or more of fentanyl, 500 grams or more of methamphetamine, and other controlled substances; and one count of possession of a firearm in furtherance of a drug trafficking crime.

U.S. District Court Judge Patti Saris scheduled sentencing for May 29.
