    Two men charged with fentanyl conspiracy

    Two men were charged Wednesday in US District Court in Boston with allegedly conspiring to sell fentanyl in Lawrence and Methuen, federal prosecutors said.

    Investigators seized about 11 pounds of fentanyl from 28-year-old Antonio Rivera, a Lawrence resident, and 24-year-old Deuris Sierra, a Dominican national mostly residing in Lawrence, the Boston US attorney’s office said in a statement.

    Rivera distributed the narcotic this year in Lawrence and Methuen from at least May 16 through June 7, federal prosecutors said.


    The defendants were each indicted on one count of conspiracy to distribute and possession with intent to distribute 400 grams or more of fentanyl. The defendants were also charged with distribution of fentanyl.

    They are currently in state custody and have not had an arraignment date set or lawyers assigned to them.
