“Significant” Massachusetts fentanyl trafficker sentenced to prison after 11 guns, over 1 kilo of fentanyl, pill press, 15+ pounds of marijuana, $36,000 in cash seized

BOSTON – A Massachusetts man was sentenced in connection with his involvement in a violent gang.

According to the Massachusetts Department of Justice, Samael Mathieu, a/k/a “Hamma” or “Hamma Thang,” 26, was sentenced by U.S. District Court Judge Leo T. Sorokin to 114 months in prison and four years of supervised release. In April 2022, Mathieu pleaded guilty to RICO conspiracy and conspiracy to distribute and to possess with intent to distribute controlled substances.

Mathieu is one of 10 defendants indicted together in June 2020 as part of a broader federal sweep targeting numerous NOB street gang members and associates in which 31 total defendants were charged. All of Mathieu’s co-defendants have pleaded guilty to various charges and are scheduled to be sentenced in the upcoming months.

According to court documents and the DOJ, NOB – an abbreviation for the Norton/Olney/Barry streets in Dorchester – is a violent enterprise whose members and associates are involved in numerous types of criminal activities, including murders, attempted murders, armed robberies, drug trafficking, sex trafficking and illegal firearms offenses. During the investigation, numerous contraband items were seized including 11 firearms, over one kilogram of fentanyl (including over 2,000 fentanyl pills manufactured to appear as commercial oxycodone pills), a commercial pill press, over 15 pounds of marijuana and approximately $36,000 in cash.

Mathieu was a significant fentanyl trafficker and active and violent member of the NOB gang who supplied drugs to and supported various crimes on behalf of the gang. On Oct. 1, 2019, a search of a residence used by Mathieu resulted in the seizure of drugs including fentanyl, pills, and suboxone, drug trafficking paraphernalia, and two loaded handguns.
