DeKalb County early Friday evening identified the man killed in a Dunwoody shooting on Thursday. Police said they're "aggressively" trying to figure out why Allen Wolfenbarger, 30, was shot. "There are no new developments," police spokesoman Bettina Durant said in the shooting death of man that police believe had stopped at the Texaco in the 4300 block of North Peachtree Road to buy gas.
