A 16-year-old was charged as an adult on Wednesday in the killing last week of a man in the Congress Heights neighborhood of Southeast Washington, according to D.C. police and court documents.

Anthony Williams, who lives in Southeast, was ordered detained until a preliminary hearing scheduled for Nov. 25 in D.C. Superior Court. He is charged with second-degree murder in the Nov. 5 shooting of 25-year-old James Edward Booker, also of Southeast.

Police said Booker was shot four times — in his right and left chest, right thumb and buttocks — during a confrontation in the 3200 block of 6th Street SE, in front of Martin Luther King Jr. Elementary School. Police said he ran several blocks to the 500 block of Alabama Avenue SE, where he collapsed.

The arrest affidavit filed in D.C. Superior Court says an officer found him a few minutes before 10 p.m., conscious and able to say, “I don’t know,” when asked who shot him. He died less than an hour later at Howard University Hospital, at 10:48 p.m.

Court documents say that a witness saw the young suspect, holding a revolver in his right hand, talking with Booker, and then saw the suspect raise his right hand several times before running away. The witnesses said he had seen the 16-year-old hanging in the neighborhood often and that he appeared in a video posted on YouTube.

Police say Williams belongs to a crew that has a series of videos on the Internet site in which members appear talking about life on the streets. They flash money and talk of being “O.G.” — original gangster — and they call their group a “movement.” One says, “If I don’t got my gun, I got my knife.” Various names include “620 Long Money” and “620 Da Squad Gutter.” The “620” is defined as an expletive in urban slang.

Police said in court documents that Williams appears on one video wearing a light blue windbreaker jacket with white script on the back. The witness to the killing had a picture of Williams wearing that jacket saved on his smartphone, police. said. The witness also said that the suspect had argued with the victim’s relatives in the past, according to the affidavit.
