"Detectives have identified the deceased victim as a 16-year-old male," police said in the statement.
Another 14-year-old victim in the incident is still receiving treatment from gunshot wounds at Harborview Medical Center, the statement said.
Seattle Police Chief Carmen Best said during a press conference on Monday that investigators have no information about the incident and no leads on possible suspects.
Last week, three people were shot within 48 hours, including a 19-year-old man who died, according to police reports.
City efforts to dismantle the zone have so far been thwarted by protesters, who reportedly blocked authorities from reaching the victim who was fatally wounded in last week’s shootings.
Last week, one of the protest leaders, David Lewis, told Sputnik that the Capitol Hill Organized Protest (CHOP) area is not an autonomous zone as alleged by President Donald Trump and others. He also said the group has no plans to secede.
