Police, FBI scrutinizing video footage of Capitol Hill intern's shooting

No arrests have been made in the shooting death of a Capitol Hill intern, but police have recovered a black Acura in the suburbs and are analyzing video camera footage from the scene, D.C. police chief Pamela Smith said Thursday.

The big picture: The death of 21-year-old Eric Tarpinian-Jachym — who police say was an innocent bystander caught in crossfire — got the attention of federal officials after Rep. Ron Estes (R-Kan.) announced his killing on Wednesday evening.

Driving the news: D.C. police are working with ATF and the FBI, which is helping enhance "grainy" video footage in the hopes of releasing images to the public, Smith said.

• Two groups had an altercation near the scene on Monday. It escalated into gunfire at 7th and M streets NW outside of the Mt Vernon Square/Convention Center Metro stop around 10:30pm.
• Two others shot — a woman and a 16-year-old boy — were taken to the hospital with injuries, police said. Tarpinian-Jachym died on Tuesday.
• A vehicle linked to the suspects was found in a "neighboring jurisdiction," Smith said.
• Detectives are studying footage to identify any weapons used, none of which have been recovered yet, Smith said.

What they're saying: "It is our pledge to bring whoever is responsible to justice," Mayor Muriel Bowser said at a press conference Thursday.

Zoom out: Tarpinian-Jachym's killing is the 85th homicide so far this year, and the tragedy has the potential to focus more congressional attention on the management of the District.

• Congressional intervention in D.C.'s public safety laws has increased in the past two years, with the House passing a bill last month to allow the D.C. police union to negotiate disciplinary issues in the collective bargaining process.
• Homicides are slightly down (by 4%) compared to the same time last year, according to police data.
