Two District men pleaded guilty Friday to killing a rider on a Metro bus last year, the U.S. Attorney’s office said.

Delron Atchison, 24, of Northeast, and Vincent Gray, 22, of Southeast, pleaded guilty to second-degree murder in D.C. Superior Court. Atchison also pleaded guilty to three counts of assault with a dangerous weapon because three other passengers were seated near the man the pair targeted.

Authorities said that the two men fought with the victim, Demetrius Thompson, 22, of Southeast, on Oct. 19 last year. Shortly after the fight, the assailants boarded a bus around midnight in the 2100 block of Alabama Avenue SE in which Thompson was a passenger. Atchison pulled out a handgun and shot Thompson twice, according to prosecutors.

The incident was caught on security video, and the two were arrested five days later in Orlando. They are set to be sentenced Dec. 14.
