Authorities were on a nationwide manhunt for a marketing professor in the shooting deaths of three people Saturday at a community theater near the University of Georgia. Athens-Clarke County Police Capt. Clarence Holeman said the shooter was the ex-husband of one of the people killed, Marie Bruce, who was in her 40s. Police were looking for George Zinkhan, 57, who has been a professor at the university in Athens since the 1990s. The other victims were a male in his 40s and another male in his 60s. The three were shot multiple times, Athens-Clarke County Coroner Sonny Wilson said. Police were called to the Athens Community Theater about a kilometer from campus at about 12:25 p.m. and found three people shot to death outside, Holeman said. Two others were hit by shrapnel, and their conditions were not immediately known, Holeman said.
