Drug dealers Nelson Mora and Christopher Nagle have copped to slinging thousands of deadly fake pills laced with fentanyl and meth on Massachusetts's North Shore, authorities said. Mora, a 31-year-old from Lynn, and Nagle, a 30-year-old Revere native, each pleaded guilty to a conspiracy charge related to their drug-dealing deeds; Nagle tacked on an additional plea for a major meth stash over half a kilo, official sources announced.

The duo's guilty pleas entered in the Boston federal court indicate their roles in a large-scale drug trafficking outfit known for pushing bogus meds; Nagle faced the music first on Aug. 5, followed by Mora on Aug. 13, with Chief Judge F. Dennis Saylor IV hammering out their fate, the perps could spend up to two decades in the slammer, get slapped with supervision post-release, and cough up to a whopping $1 million fine, according to a statement by the U.S. Attorney's Office.

The Nagle brothers were pegged as the head honchos behind this drug-peddling pyramid, spreading their poison—ranging from meth-laced Adderall knockoffs to cocaine and beyond—like a virus through the Bay State's veins. The feds snagged more than 74,000 fake Adderall pills during a raid at Christopher Nagle's pad, weighing in over 24 kilograms of illicit product. These shady siblings made sure to spread the wealth, allegedly supplying their network of dealers, including Mora, with the means to press and pass off these perilous pills.

Marking defendants numbers 10 and 11 swayed to spill in court, Mora and Nagle's pleas edge the prosecutors closer to cleaning up this criminal cacophony. If Christopher Nagle's megastash conviction sticks, he's looking at a minimum of a decade behind bars and potentially a life sentence, while both he and Mora could be monitored till death's door post-prison and face fines as fat as $10 million. This crackdown comes courtesy of a crew of law enforcement, including the DEA, state police, and local departments supported by the feds.
