DC police are searching for a third suspect charged in the murder of Capitol Hill intern Eric Tarpinian-Jachym. Here's what we know about the case.

DC Metropolitan Police are actively searching for a third suspect charged in the murder of Eric Tarpinian-Jachym, a Capitol Hill intern whose death has shaken Washington's tight-knit Hill community. At least two other individuals have already been charged in connection with the killing, and authorities are pressing to bring the final suspect into custody.

🔑 Key Takeaways

  • DC Metropolitan Police are searching for a third suspect charged in the murder of Capitol Hill intern Eric Tarpinian-Jachym.
  • At least two other suspects have already been charged in connection with the killing.
  • Tarpinian-Jachym's death has prompted urgent conversations about intern safety in and around Capitol Hill.
  • The case is drawing scrutiny from Members of Congress and Hill leadership offices.
  • MPD is urging anyone with information on the third suspect's whereabouts to contact authorities immediately.

A Capitol Hill Community Shaken by Violence

Eric Tarpinian-Jachym was not just another name on a staff directory. Like thousands of young people who flood Capitol Hill every year — fresh out of college, full of ambition, staffing offices from Rayburn to Russell — he came to Washington to build something. His murder has cut through the usual noise of the Beltway and landed like a gut punch on every intern, every young staffer, every Hill rat who walks those marble hallways and then catches the Metro home alone at night.

The DC Metropolitan Police Department (MPD) confirmed that three suspects have been charged in connection with the killing. Two are already in custody. The third remains at large, and MPD is treating the search as urgent. The department has urged residents with any information to come forward immediately.

As of this reporting, MPD has not publicly released the identity of the outstanding third suspect, but investigators are actively working the case. For the young professionals who commute through Eastern Market, walk the Hill's residential streets between Pennsylvania Avenue SE and Lincoln Park, and grab coffee at the same spots Tarpinian-Jachym likely frequented — this is personal.

Who Was Eric Tarpinian-Jachym?

Capitol Hill interns occupy a unique place in Washington's ecosystem. They're the engine room of Congress — answering constituent calls, running legislation to the floor, attending hearings, and absorbing the machinery of American democracy at its most raw. Most are in their early 20s, many are far from home, and nearly all of them navigate DC's streets on a shoestring budget.

Tarpinian-Jachym's death is a stark reminder that the prestige of a Hill badge doesn't insulate young people from the dangers that can surface in any major American city. The Washington Post has covered the broader challenge MPD faces in addressing violent crime in neighborhoods adjacent to the Capitol complex, where the contrast between institutional power and street-level vulnerability is sharpest.

For DC's political community, the loss of an intern to homicide is rare enough to be genuinely alarming. Hill offices have begun quietly circulating safety reminders to their staff, and at least one senior Member's office confirmed to WDCM that leadership is monitoring the situation closely.

MPD's violent crimes unit is leading the investigation. Two suspects already charged suggests prosecutors at the US Attorney's Office for the District of Columbia have enough to move — but the third outstanding charge signals investigators believe there's a critical piece of this case still walking free on DC streets.

That detail matters. In cases involving multiple defendants, the uncharged or uncaptured suspect often holds key information — or played a central role that prosecutors want to lock down before trial. The US Attorney's office, which handles felony prosecutions in the District, typically coordinates closely with MPD on multi-defendant murder cases to ensure charges stick and plea negotiations don't unravel the broader case.

MPD has not disclosed the specific circumstances of the killing — location, manner, or motive — pending the active search. But FOX 5 DC, which first reported the third suspect charge, confirmed that the investigation is moving swiftly. Anyone with information is asked to call MPD's tip line at 202-727-9099 or text 50411.

Why This Matters in Washington

Capitol Hill is not just a neighborhood — it's a symbol. And when violence reaches it in the form of a young intern's murder, it forces a conversation that Washington's political class sometimes prefers to avoid: the city's uneven relationship with public safety. The Hill's residential streets — from Barracks Row to Stanton Park — are home to staffers, lobbyists, and longtime DC residents alike. They share the same sidewalks, the same bus stops, the same vulnerability.

For young Black and brown Washingtonians who have watched violent crime stats rise and fall with administrations and police chiefs, the political machinery that accelerates when a Hill intern is killed can feel frustratingly selective. That tension — between who gets urgency and who waits — is woven into DC's identity. See our DC Power Players Index for a broader look at the figures shaping how the District responds to public safety crises.

What's undeniable is this: Eric Tarpinian-Jachym came to Washington to be part of something. His death demands accountability — and MPD, the US Attorney, and Congress should feel the weight of that expectation equally. Track DC politics and power moves as this case develops.

What Happens Next: Congress, MPD, and a City Watching

Members of Congress whose offices employed Tarpinian-Jachym or whose staff knew him are expected to issue statements as more details emerge. The Capitol Police — a separate law enforcement agency from MPD that handles security on the Capitol campus itself — is also likely monitoring the case, given the victim's connection to the institution.

On the investigative side, the clock is ticking. The longer the third suspect remains at large, the greater the risk that evidence degrades, witnesses become harder to reach, or the narrative of the case shifts in ways that complicate prosecution. NPR has reported extensively on the structural challenges DC prosecutors face in multi-defendant homicide cases, particularly when defendants are charged but not yet apprehended.

The bottom line: Three people have been charged in the murder of a young man who came to Washington to serve the public. Two are in custody. One is not. MPD needs the public's help — and the public deserves answers.
