D.C. police arrested an 18-year-old man in the killing of a 15-year-old boy near Nationals Park in October.
Thomas Johnson was shot and killed near his home in the 1300 block of Half Street SW about 1:30 p.m. Oct. 9, just hours before thousands of Nats fans were set to attend a playoffs watch party at the stadium.
Witnesses said someone chased him and then shot him in a courtyard. They said they heard five shots. Johnson fell to the ground after being shot multiple times.
The victim had been targeted, police said.
Police arrested 18-year-old Javon Gunter Friday and charged him with first-degree murder while armed.
Nationals Park is about three blocks east of the scene of the shooting.
