Authorities in the nation's capital say more than one person is responsible for the slayings of four people inside a Washington mansion last week. A fugitive task force arrested Daron Dylon Wint Thursday night, and took five people who were with him into custody. Wint is the only person currently charged with the murder of Savvas Savopoulos; his wife Amy; their 10-year-old son, Philip; and their housekeeper, Veralicia Figueroa. But a court document suggests investigators aren't done making arrests. It says "the crimes described in this affidavit required the presence and assistance of more than one person."
