At least one member of the U.S. Marshals Service shot and killed a man in Northeast D.C.’s Mayfair neighborhood Wednesday afternoon, a law enforcement source told WTOP.

The shooting happened around 2:30 p.m. in the 3700 block of Hayes Street, on the eastern banks of the Anacostia River just southwest of Kenilworth. Julian Marquette Bailey, 43, was killed.

According to a U.S. Marshals spokesman, marshals responded to a call about a person threatening to kidnap and hurt someone while holding a gun on Hayes Street.

Marshals were already patrolling the area as part of President Donald Trump’s law enforcement surge in D.C., and were the first to respond to the reported crime scene.

Marshals found the victim at the location and found Bailey on Hayes Street.

“The suspect, they said, did produce a weapon and pointed it at deputies. And it was then, according to this U.S. Marshals spokesman, that a marshal shot and killed this person,” WTOP reporter Scott Gelman said from the scene. “There’s still a lot of unanswered questions.”

In a statement to WTOP, U.S. Park Police said they tried saving the suspect’s life at the location and pronounced him dead at the scene. Bailey was airlifted by helicopter to a hospital after the shooting.

The U.S. Marshals Service told WTOP no law enforcement personnel were injured. The Force Investigations Team of D.C. police’s Internal Affairs Bureau is investigating the shooting.
