Three Teens Charged As Adults In D.C. Armed Robbery
Three teenagers have been charged as adults in connection with an armed robbery in Southeast Washington, D.C., underscoring federal prosecutors’ tougher approach toward violent juvenile crime in the nation’s capital. The defendants—Onyx Austin, 17, Pierce Arrington, 17, and Reggie Mateck, 16—made their initial appearances in D.C. Superior Court after being accused of participating in the violent robbery of two victims on July 6.
According to prosecutors, the robbery occurred in the 3300 block of 7th Street SE, where Metropolitan Police Department officers responded to reports of an armed assault. Court documents allege that one suspect placed both victims in chokeholds while another pressed a handgun into one victim’s ribs and threatened them. During the robbery, the suspects allegedly stole two cell phones, a wallet, and later accessed one victim’s bank accounts, taking approximately $1,700.
Law enforcement officers later tracked down the three suspects and arrested them at the residence of one suspect’s mother. The arrests were carried out as part of the “Make D.C. Safe and Beautiful” initiative, a joint federal and local law enforcement operation launched in support of a presidential executive order focused on reducing violent crime, combating illegal firearms, and increasing accountability for repeat offenders.
Because of the seriousness of the allegations, prosecutors elected to charge all three defendants as adults rather than through the juvenile justice system. Charging juveniles as adults allows prosecutors to pursue harsher penalties when the alleged offenses involve violent felonies such as armed robbery and firearm-related crimes. The decision reflects the government’s position that particularly serious juvenile offenses warrant stronger criminal consequences to protect public safety.
The case also reflects a broader crackdown on violent juvenile crime in Washington, D.C. U.S. Attorney Jeanine Ferris Pirro said the prosecution sends a clear message that violent offenses committed by minors will be aggressively prosecuted. She criticized what she described as lenient approaches toward repeat juvenile offenders and emphasized that victims’ rights must remain the priority regardless of a defendant’s age. Pirro stated there would be “zero tolerance” for violent crimes involving firearms if the allegations are proven in court.
Although the charges are serious, the three teenagers remain presumed innocent unless proven guilty beyond a reasonable doubt. Their initial court appearances marked the beginning of criminal proceedings, during which prosecutors must present evidence supporting the allegations. Defense attorneys will have the opportunity to challenge the government’s case as it moves through the judicial process.
The prosecution comes amid continuing concerns over rising violent crime involving juveniles in the District. Federal and local officials have increasingly relied on coordinated enforcement strategies targeting armed robberies, illegal firearms, and repeat violent offenders. The current initiative seeks not only to arrest suspects but also to deter future offenses through stronger enforcement and prosecution.
Legal observers note that charging juveniles as adults remains one of the most significant prosecutorial decisions in violent crime cases because it can substantially increase sentencing exposure if convictions are secured. The outcome of this case may influence future decisions involving juvenile defendants accused of serious firearm-related offenses in Washington, D.C.
As the case proceeds, the court will determine whether the prosecution can prove the allegations against the three defendants. The proceedings are expected to be closely watched as part of the District’s broader effort to address violent crime while balancing public safety and juvenile justice considerations.
