A man was fatally stabbed at the Woodley Park Metro station early Saturday morning, and D.C. police say they are questioning “several suspects” in connection with the incident.

The stabbing occurred about 1:15 a.m., said Officer Paul Metcalf, a D.C. police spokesman. He said the victim was taken to a nearby hospital, where he was pronounced dead. Metcalf said it was possible others were also hurt, though, none fatally.

Other details of the incident remained unclear. Metcalf said investigators were still investigating what sparked the stabbing and whether it started inside or outside the Metro station. Of the suspects, Metcalf said investigators were trying to “see what part they played” and, in some cases, to “see if they were actually involved.”

“It’s a larger, more complicated investigation,” Metcalf said.

Jesse Blumenthal, 23, of the District, said that when he went into the station just before 1:30 a.m., he saw a crowd of people around someone lying on the ground, in front of the turnstiles. Blumenthal said a woman was trying to resuscitate the apparent victim.

Blumenthal said that he continued down to the platform, and within minutes, police were handcuffing several young men and telling them to sit on the ground.

“It was clearly tense, and there was something going on,” Blumenthal said.

Blumenthal said he saw police cuff five or six people. He said officers searched the train tracks and sent several trains through the station without allowing the conductors to open the doors.

A Metro spokesperson did not immediately return a phone message seeking comment.
