A shootout in Bushwick yesterday afternoon left a woman dead—an innocent bystander who was watching her 8-year-old nephew play nearby. 44-year-old Jesselle Page was shot in the upper torso around 4:45 p.m. when two men began firng at one another as she was walking into her housing project on Moore Street. A neighbor told the News, "The blood was all over the floor." Page was rushed to Woodhull Hospital where she was pronounced dead. The Post reports that in nearby South Williamsburg yesterday another shooting at a children's birthday party at South Second and Havemeyer streets left a young mother injured.
