Former D.C. Cashier Convicted of Armed Robbery Against Former Employer

Washington, D.C. – A former cashier has been convicted of multiple felony charges after carrying out a violent armed robbery against his former employer, the U.S. Department of Justice announced.

Conviction and Charges

A jury found Stephon Martin, 25, of Washington, D.C., guilty of robbery while armed, assault with a dangerous weapon, assault with significant bodily injury while armed, and felony destruction of property. The verdict follows a trial detailing a brutal attack against Martin’s previous workplace, a local tobacco store.

Timeline of the Crime

According to prosecutors, Martin was laid off from the store on October 18, 2024. Nearly six months later, on April 15, 2025, he returned to confront the store’s owner.

Authorities said Martin assaulted the victim and stole cash directly from his pocket during the initial attack. Roughly 30 minutes later, Martin came back to the store using his employee key. This time, he struck the victim with a wooden board, inflicted additional injuries, and stole money from the register.

Prosecutors added that Martin also removed a shelving unit filled with merchandise before leaving the store a second time.

Victim’s Injuries and Losses

The store owner sustained physical injuries during the assaults and required medical attention. Beyond the personal harm, the business suffered financial losses from both the stolen cash and merchandise, as well as damage caused during the robbery.

Sentencing Scheduled

Martin is scheduled to be sentenced on November 7, 2025, before Superior Court Judge Judith Pipe. Given the severity of the charges, he faces the possibility of a lengthy prison sentence.

Community Impact

The case has drawn attention to workplace security, especially for small businesses employing staff who may retain keys or access after being let go. Prosecutors emphasized that Martin’s actions were not only violent but premeditated, returning to the store after already robbing it once earlier that day.

Justice Department Statement

Officials with the U.S. Department of Justice underscored the seriousness of the case, noting that violent crimes against employers and businesses can have long-lasting impacts on both victims and the wider community. The conviction, they said, demonstrates the importance of pursuing accountability in cases involving both personal assault and property damage.

Looking Ahead

As sentencing approaches, the victim and community members await closure in a case that highlights the dangers business owners face when targeted by individuals familiar with their operations. Prosecutors say the conviction sends a message that violent retaliation against employers will be met with significant legal consequences.
