Dominican National Indicted for Fentanyl Distribution While on Federal Supervised Release for Heroin and Cocaine Trafficking Conviction

A Dominican national living in Lawrence, Massachusetts, Wagner Ismael Mejia Sanchez (also known by several aliases), has been indicted on one count of distribution of and possession with intent to distribute approximately 1,000 fentanyl pills—while already serving a term of federal supervised release for a prior drug trafficking conviction.

The Charges: Distribution While on Supervised Release

According to the indictment, Mejia Sanchez was arrested after allegedly distributing 96.2 grams of fentanyl during a controlled transaction carried out by a law enforcement agent. This act violated the terms of his federal supervised release from a 2015 conviction for heroin and cocaine trafficking. He had originally been sentenced to 39 months in prison followed by 10 years of supervised release.

With the new charge he faces:

  • A mandatory minimum of 5 years and up to 40 years in federal prison
  • At least 4 years and up to a lifetime of supervised release
  • Fines up to $5 million

Because he has a prior conviction, those penalties may escalate to a minimum of 10 years to life in prison, at least 8 years of supervised release, and up to $8 million in fines. The defendant also faces deportation upon completion of his sentence.

Drug Distribution vs. Drug Trafficking: What’s the Difference?

People often use the terms “drug distribution” and “drug trafficking” interchangeably—but in the eyes of the law, they can mean very different things.

  • Drug Distribution refers to the sale or delivery of controlled substances in smaller quantities.
  • Drug Trafficking typically involves larger quantities and often includes transportation across state or international borders.

The difference largely comes down to quantity, scope, and intent. Federal prosecutors may pursue trafficking charges when the accusations involve large quantities or interstate activity. Both charges carry severe penalties, and anyone facing such charges needs the support of experienced legal counsel.

Supervised Release Violations: A Sentence Within a Sentence

When someone violates supervised release—especially by committing a new felony—the penalties are compounded. Courts may:

  • Revoke the supervised release
  • Impose additional prison time, up to the full length of the original supervised release term
  • Add this time on top of the sentence for the new offense

In Mejia Sanchez’s case, that could mean several additional years behind bars.

Why You Need a Federal Drug Defense Attorney

Facing a federal drug charge—especially one involving fentanyl—is a legal battle with extremely high stakes. Prosecutors are aggressive, sentencing guidelines are rigid, and the consequences can last a lifetime.

An experienced federal drug defense attorney can:

  • Challenge the evidence and legality of searches or wiretaps
  • Scrutinize how drugs were tested, weighed, or linked to the accused
  • Explore sentencing alternatives or negotiate favorable plea agreements
  • Help defendants avoid or minimize enhancements due to prior convictions

Federal drug cases are not the place for inexperience or hesitation. If you or someone you love is facing drug charges, don’t wait.
