Police said gunmen in two speeding cars opened fire on a crowd, wounding 13 people on March 11.
Four days after the attack, detectives arrested Craig Steven Wilson, 19, of Southeast.
He has been charged with assault with intent to kill and is scheduled to go to trial in September.
Police said another suspect, whose name was not released, is jailed in another jurisdiction on unrelated charges.
Bobb turned himself into D.C. police Thursday evening, officials said.
The March shootings occurred in front of Tyler House, a subsidized apartment building in the 1200 block of North Capitol Street that is near a large nightclub.
The area is blocks from NoMa, short for north of Massachusetts Avenue, a developing neighborhood of upscale condos, shops and restaurants. D.C. Police Chief Cathy L. Lanier has made such areas a law enforcement priority.
Police said the gunmen opened fire about 2:10 a.m., after the nearby Fur nightclub had closed, and authorities have said that many of the victims had just come from the club.
A GPS tracking device attached to Wilson’s ankle because he had violated parole on a stolen property conviction showed he was at the club before the shooting and in front of Tyler House at the time it began, according to court papers.
Authorities have released a video that shows two cars speeding south on North Capitol Street with bursts of gunfire visible from the windows and people tumbling to the sidewalk after being struck.
Police have not released a motive, and authorities familiar with the case said Thursday it is unclear if anyone in the crowd had been specifically targeted. Police have not been able to tie the shooting to the nightclub, although in March, Lanier said patrons often hung out in front of Tyler House after closing time.
The club’s building has been sold, and officials expect Fur to be gone soon.
On May 6, police said a 19-year-old man was stabbed in the chest and suffered a broken cheekbone during a fight at a go-go concert at Fur, and Lanier ordered the club shuttered for 72 hours.
On Wednesday, the D.C. liquor control board unanimously voted to keep it closed until it is in compliance with regulations. It was the third time in three years that Lanier had ordered Fur closed after a violent attack.
