Lowell Man Pleads Guilty to Trafficking Guns, Drugs, Machinegun Conversion Devices

BOSTON – A Lowell man has pleaded guilty to multiple federal crimes after he was recorded illegally selling numerous guns, thousands of methamphetamine pills and machineguns.

Billy Chan, a/k/a “Juju,” 20, pleaded guilty on June 6, 2025 to one count of engaging in the business of dealing in firearms without a license; one count of conspiracy to distribute and to possess with intent to distribute 500 grams and more of methamphetamine; one count of distribution and possession with intent to distribute methamphetamine; and one count of transfer and possession of a machinegun. U.S. District Judge Angel Kelley scheduled sentencing for Sept. 17, 2025.

On five different dates in Lowell between March 2023 and June 2023, Chan sold three handguns, four machinegun conversion devices and approximately 2,000 pills marketed as “Adderall,” to undercover law enforcement. Laboratory testing confirmed that the “Adderall” pills were homemade methamphetamine pills pressed with caffeine and designed to look like the genuine pharmaceutical product. Chan trafficked the counterfeit pills with an alleged co-conspirator who was a member of the Asian Boyz gang. The investigation revealed that, in 2023, Asian Boyz gang members and associates had access to a plentiful supply of counterfeit pills containing methamphetamine, which they distributed widely across the Merrimack Valley region.

During a recorded meeting with a cooperating source, Chan said he worked at a machine shop, could make the machinegun conversion “switch” devices himself and gave instructions and demonstrations on how to install the “switches” on a pistol. A few days later, Chan sent the source a video of a person shooting a fully automatic handgun into the air, with the message: “I let my boys test the switch.”
