A federal jury has returned a guilty verdict against Marshun Lewis of Memphis, for a series of armed robberies of United States Postal Service carriers and related bank fraud offenses, U.S. Attorney D. Michael Dunavant for the Western District of Tennessee announced this week.
According to court evidence cited by the U.S. Attorney’s Office, Lewis carried out armed robberies of postal carriers in August 2023 and again in October, November, and December 2024.
Prosecutors said Lewis acted as a masked gunman, targeting carriers to steal specialized postal keys used to access blue collection mailboxes throughout Memphis. Investigators located Lewis’s vehicle at the scenes of the robberies via surveillance footage.
Using the stolen keys, Lewis removed checks and money orders from the mail and used them to commit bank fraud by altering payee information on the stolen checks and money orders and deposited them into third-party accounts for later withdrawal.
Postal Inspectors later executed a search warrant at his residence, where they recovered stolen mail and a keychain belonging to one of the stolen postal keys.
Further, text messages found on Lewis’s phone linked him to each robbery and to multiple co-conspirators involved in the fraud scheme. Authorities determined the total value of stolen checks and money orders exceeded $940,000.
After a four-day trial, 25-year old Lewis, was convicted of four counts of robbery, four counts of brandishing a firearm during and in relation to a crime of violence, one count of conspiracy to commit bank fraud, one count of bank fraud, and one count of possession of stolen mail.
Due to the firearm convictions, Lewis faces a mandatory statutory minimum sentence of 28 years in federal prison.
Sentencing is scheduled for April 10, 2026, before U.S. District Judge Thomas L. Parker.
As noted by the U.S. Attorney’s Office, there is no parole in the federal system.
“This office takes very seriously our duty to protect the safety of United States Postal Service employees and the sanctity and security of the U.S. Mail. Armed robberies are brazen and disturbing acts of violence that terrorize our community and must be met with significant consequences. This dangerous offender has sown violence and greed, and as a result of this guilty verdict, he will now reap the full measure of consequences for his criminal conduct,” U.S. Attorney Dunavant said.
The Memphis verdict comes amid a string of recent federal cases nationwide involving robberies of postal workers.
Earlier this month, a man in Cuyahoga County, Ohio, was charged by criminal complaint in the Northern District of Ohio with robbing a USPS carrier while she was on her route in Akron.
In Western New York, federal prosecutors announced on December 17, 2025, that Shyasia Kelis McCullough, 25, of Rochester, was sentenced to 12 months in prison after being convicted of robbing a postal worker.
Similarly, in the District of Colorado, a Denver man was indicted on December 16, 2025, on 21 federal counts, including robbery of a U.S. Postal Service worker, brandishing a firearm in furtherance of a crime of violence, bank fraud, and aggravated identity theft.
