Washington D.C. police issued an arrest warrant late Wednesday for a suspect in the murder of a corporate executive, his wife, their 10-year-old son, and a family housekeeper in their home last week. The suspect is named as 34-year-old Daron Dylan Wint. He is charged with first-degree murder while armed. Police told the Washington Post that Wint is a native of Maryland, and they did not know his whereabouts.
