BOSTON — A U.S. Postal Service manager allegedly turned the mail system into a pipeline for cocaine, stealing packages he knew contained narcotics and funneling them into the streets. Shawn M. Herron, 44, of Whitman, Mass., was indicted yesterday on one count of conspiracy to possess cocaine with intent to distribute and one count of theft of mail by a postal employee.
Herron, employed by the Postal Service since September 2005, most recently served as Manager of Customer Services at the Fall River Post Office. Before that, he held the role of Supervisor of Customer Service at the Canton Post Office. Instead of safeguarding the mail, prosecutors say he weaponized his access, targeting parcels flagged by law enforcement or coming from high-risk corridors like Puerto Rico and West Coast states.
Court documents allege Herron used internal Postal Service databases to track priority shipments suspected of carrying controlled substances. Once these packages arrived at the Fall River facility, he retrieved them from the mail stream and brought them directly to his personal office space—where he opened them and stole the contents. What should have been intercepted or properly reported instead vanished into his criminal operation.
The indictment follows an investigation that began with Herron’s arrest via criminal complaint in February 2020. Authorities say his actions exploited the very system he was sworn to protect, turning federal infrastructure into a distribution network for illicit drugs. The breach strikes at the heart of public trust in federal services and raises alarms over internal oversight.
If convicted, Herron faces up to 20 years in prison, five years of supervised release, and a $500,000 fine on the drug conspiracy charge. The mail theft charge carries a maximum sentence of five years in prison, three years of supervised release, and a $250,000 fine. A federal district court judge will determine the final sentence based on the U.S. Sentencing Guidelines and other statutory factors.
The case is being prosecuted by Assistant U.S. Attorney Eugenia M. Carris of the Public Corruption & Special Prosecutions Unit. The announcement was made by United States Attorney Andrew E. Lelling; Matthew M. Modafferi, Special Agent in Charge of the U.S. Postal Service Office of Inspector General; and Joseph W. Cronin, Inspector in Charge of the U.S. Postal Inspection Service. As with all federal cases, Herron is presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
