near the corner of Connecticut Avenue and Van Ness St. The gunfire erupted shortly before 3:30 p.m. The man had been “linked to social media postings” that emerged as part of the investigation, Assistant Police Chief Stuart Emerman said. Police did not release the suspect’s name, pending notification to his family, but earlier had said they were seeking a 23-year-old Virginia man as a person of interest in the shooting. For hours, authorities had warned worried residents to stay inside their homes while they conducted a massive manhunt for the shooter. The four victims - a 54-year-old man who is a retired police officer, a woman in her 30s, a woman in her mid-60s who was grazed by a bullet, and a 12-year-old girl who was shot in the arm - were all expected to recover, police said. The shooting was recorded and posted online on 4chan, an online message board. Hours earlier, police believe the man had erected a “sniper-type setup” with a tripod and rifle in his apartment and began firing indiscriminately at people walking below, Metropolitan Police Chief Robert Contee said. The suspected gunman was found dead Friday night inside an apartment at the scene as Metropolitan Police Department officers conducted door-to-door searches of buildings in the area. WASHINGTON (AP) - At least four people, including a 12-year-old girl, were shot when a gunman unleashed a flurry of bullets in the nation’s capital Friday, leading to lockdowns at several schools and leaving a community on edge before the suspect was found dead hours later.
