FAIRFAX CITY, VA — A Maryland man has been arrested on a federal criminal complaint stemming from the gunpoint robbery of a U.S. Postal Service mail carrier in Fairfax City last year, an incident that investigators linked to a broader operation involving stolen mail, fraudulent checks and postal master keys, according to federal court documents.
Quiron Ellis Greene was arrested Thursday, after federal prosecutors filed a criminal complaint accusing him of assault with intent to rob a postal employee of U.S. government property. The charge stems from a Nov. 4, 2025, robbery near 3981 Wilcoxson Drive in Fairfax City.
According to a 14-page affidavit filed by a U.S. Postal inspector in U.S. District Court in Alexandria, Greene was one of three men involved in the robbery, during which an accomplice allegedly pointed a handgun at a mail carrier and forcibly removed a postal master key from the carrier's belt.
The robbery occurred around 2:43 p.m. while the postal employee was delivering mail in the Wilcoxson Drive area, according to the affidavit.
Investigators said two men approached the carrier. One of them displayed a camouflage-colored handgun and pointed it at the employee before grabbing a USPS master key, commonly known as an "arrow key," from the carrier's belt loop. The force of the theft broke the belt loop, according to court records.
The two men fled on foot and entered a light-colored Chevrolet Impala driven by a third individual, investigators said.
Before the suspects escaped, the mail carrier used a cellphone to photograph two men entering the vehicle. That photograph would later become a central piece of evidence in the investigation.
Postal inspectors distributed a reward poster featuring the photograph, prompting a tip from someone who recognized Greene as a possible participant.
During a June 5, 2026, interview, the tipster provided investigators with screenshots of text messages allegedly exchanged with Greene on the day of the robbery.
In those messages, Greene described participating in a "drill money move" that required him to "take something that belongs to somebody else," according to court records.
He also discussed check fraud and described the incident as "scary but we made it back safe," according to the affidavit.
Investigators obtained cellphone location records that placed a phone associated with Greene near the robbery scene shortly before the incident.
Federal investigators interviewed Greene on July 13 at the Harford County Detention Center in Maryland, where he was being held following an arrest on an outstanding warrant related to aggravated assault charges, according to court records.
During the interview, Greene acknowledged being present during the Fairfax City robbery but denied possessing the firearm, court records said.
"I didn't have the gun or anything, but I was there," Greene told investigators, according to the affidavit.
Greene also identified himself in the photograph taken by the mail carrier and identified the second man as the person who displayed the handgun and stole the postal key, according to the affidavit.
During a second interview July 20, Greene identified that individual in a photographic lineup, investigators said.
Greene also told investigators that the getaway driver, whom he knew by the nickname "Mar," selected the Fairfax City location for the robbery.
According to the affidavit, the license plate displayed on the getaway vehicle had been reported stolen in Maryland.
Investigators also analyzed cellphone records showing activity consistent with Greene and the alleged getaway driver traveling from Maryland into Northern Virginia on the day of the robbery and returning to Maryland afterward.
The investigation expanded beyond the original robbery after authorities identified and arrested the alleged gunman in Baltimore on Sept. 2, according to court records.
The man, identified in the federal affidavit as an uncharged co-conspirator, was arrested on an outstanding Virginia warrant charging robbery with a firearm and use of a firearm in the commission of a felony.
Investigators searched a Honda Civic associated with the man and recovered 10 checks bearing different names, two cellphones and gas-line antifreeze, which postal inspectors said can be used to remove ink from checks for fraudulent purposes.
Some of the checks contained addresses in Fairfax City, and some names matched bank cards recovered from the man's wallet, according to the affidavit.
Investigators also searched the man's Baltimore residence, where they reported finding a black-and-green SCCY 9mm handgun, a paper shredder containing shredded checks, blank check stock and multiple license plates.
Greene had previously told investigators that the gunman was known to carry a SCCY 9mm pistol, according to court documents.
During a subsequent interview, the alleged accomplice denied participating in the November 2025 robbery but admitted involvement in schemes using stolen checks and fraudulent debit cards to obtain money, investigators said.
He also allegedly acknowledged participating in thefts from USPS collection boxes using stolen postal master keys.
According to the affidavit, the man told investigators he had participated in approximately four such incidents during the preceding six months, sometimes targeting multiple collection boxes during a single outing.
The man also implicated Greene in stealing checks and accessing collection boxes, investigators said.
Postal inspectors explained in the affidavit that arrow keys provide access to multiple mail collection boxes, community mailboxes and apartment mail receptacles.
Although the keys themselves have an estimated replacement value of approximately $100, investigators said their resale value on the street can reach $5,000 because they can be used to facilitate widespread mail theft, identity theft and financial fraud.
Greene made his initial appearance Thursday, before U.S. Magistrate Judge William E. Fitzpatrick in Alexandria.
The court appointed federal public defender Lauren Rosen to represent him and ordered Greene temporarily detained pending further proceedings.
A preliminary and detention hearing was scheduled for 2 p.m. Friday, in the federal courthouse in Alexandria.
The federal complaint alleges a violation of 18 U.S.C. Section 2114(a), which addresses assaults committed with intent to rob a person entrusted with U.S. mail or other federal property.
As of Friday morning, the federal docket did not list an indictment or a final disposition in Greene's case.
Greene is presumed innocent unless and until proven guilty in court.
