Germantown Man Arrested for Armed Robbery at Gaithersburg 7-Eleven

The striking detail in this case wasn’t the robbery itself — it was what police found thirteen days later inside the suspect’s Germantown home: a handgun stolen out of Georgia and modified to fire fully automatic, sitting alongside a rapid-fire trigger activator. That weapon, according to Montgomery County police, is now part of the evidence against Malcolm Anderson, a 26-year-old Germantown man arrested and charged in connection with an armed robbery at a 7-Eleven on Frederick Road.

The crime unfolded on Saturday, October 17, 2026, at approximately 2:09 p.m., when officers from the Montgomery County Department of Police – 5th District responded to the 7-Eleven in the 19700 block of Frederick Road in Gaithersburg. What they found was a robbery built around an ordinary transaction: Anderson had arranged to meet the victim in the store’s parking lot to purchase a phone the victim was selling. After getting into the victim’s car to complete the purchase, Anderson allegedly struck the victim in the head with a handgun and took both the phone that was for sale and the victim’s personal phone before leaving the scene, Montgomery County police reported.

A Two-Week Investigation Ends at a Germantown Residence

Detectives identified Anderson as the suspect and obtained a warrant for his arrest. On Friday, October 30, 2026, they executed a search warrant at his residence in Germantown, where they located and arrested him. Inside the residence, they recovered the Georgia-stolen handgun modified to be fully automatic, along with other items of evidentiary value. MoCoShow, which also covered the arrest, noted that a photo of the suspect has not been released by police.

Anderson was transported to the Montgomery County Central Processing Unit, where he was charged with armed robbery, possession of a firearm with a felony conviction, possession of a stolen regulated firearm, possession of a rapid-fire trigger activator, and other related offenses. He is currently being held without bond.

Why the Gun Charges Matter Here

The armed robbery charge covers the October 17 incident itself. The stolen regulated firearm and rapid-fire trigger activator charges connect directly to the Georgia handgun police say they found in his home — a weapon that crossed state lines and was altered to fire automatically. NewsBreak’s reporting on the case confirms the same charge list and notes he remains held without bond at the Central Processing Unit.

For residents of the Frederick Road corridor, the 2:09 p.m. armed robbery in the 7-Eleven parking lot happened during an arranged meeting to buy a phone.

Case Timeline Traces Phone Sale, Warrant Execution

Anderson is being held without bond, meaning he will remain in custody as the case moves through the Montgomery County court system. Police have not released a photo of the suspect, and it is not known when, or whether, one will become public. What is known is the sequence: a phone sale arranged in a 7-Eleven parking lot on October 17, a warrant executed at a Germantown home on October 30, and a fully automatic stolen handgun recovered in between.
