A Massachusetts man who illegally trafficked guns into the Bay State, including a firearm that was found on a 14-year-old boy and used in four Boston shootings, has been sentenced to prison.

Julius Clemente, 26, was sentenced by a U.S. District Court judge to the statutory maximum penalty of 5 years in prison and 3 years of supervised release, New Hampshire U.S. Attorney Jane Young announced on Monday.

In February, Clemente pleaded guilty to conspiracy to commit firearms trafficking. Clemente conspired to traffic 25 firearms, four of which have since been found in Massachusetts.

One of the guns was recovered from the waistband of a 14-year-old boy. That firearm was previously used in four shootings in Boston, including a non-fatal shooting of a 16-year-old.

“The defendant’s criminal conduct resulted in more than two dozen firearms being illegally trafficked into Massachusetts,” Young said in a statement. “The consequences of his crime led to a juvenile being armed with a weapon, a weapon that was used in multiple shootings, one of which injured another juvenile.

“In addition, the defendant’s crime was motivated by pure greed,” the U.S. Attorney added. “The imposition of the highest possible sentence under the law sends a clear message that such conduct will result in a significant period of imprisonment.”

Clemente’s text messages indicated that he identified customers, controlled pricing, kept a substantial portion of the profits, and destroyed firearm serial numbers, making them harder for law enforcement to trace.

Also, Clemente solicited a drug customer to serve as a straw purchaser of firearms.

The Bureau of Alcohol, Tobacco, Firearms and Explosives led the investigation.

ATF Special Agent in Charge James Ferguson said, “Trafficking firearms results in additional crimes being committed and this sentence demonstrates ATF’s continued perseverance to stopping these crimes.”
