<p>A woman was killed and a man was critically wounded by a shooting Tuesday inside the building complex that houses CNN's headquarters. Police described the incident as a "domestic situation."</p><p>A man and a woman were involved in an argument near the main entrance of the complex when the man pulled a gun and shot the woman, and the armed man was then shot by a CNN security guard responding to the scene, Atlanta Police officer James Polite said.</p><p>The woman, who worked at the Omni Hotel attached to CNN Center, was identified as Clara Riddles, 22, of College Park, according to Caryn Kboudi, a spokeswoman for the Irving, Texas-based Omni Hotel chain.</p><p>Police said the man and woman had a "prior relationship." Kboudi said Riddles worked at the Atlanta hotel. She said she did not know what Riddles did at the hotel, and that the hotel was not aware of any domestic problems the woman had.</p><p>She was transported to Grady Hospital after the shooting and was pronounced dead on arrival, hospital spokeswoman Denise Simpson said. The man was in critical condition at the hospital.</p><p>CNN reported that the offices of its Internet operations, CNN.com, were immediately evacuated. Video footage showed police pointing guns at a man lying on the ground at the bottom of the escalator going from CNN Center to Omni Hotel lobby.</p><p>An announcement over the building's public-address system said there had been gunfire "with potential casualties." Police cordoned off an area by the escalators near the main entrance of the building, facing Centennial Olympic Park.</p><p>"I heard four or five shots. I really didn't see it. I got out of there quick," said Jas Stanford, 27, who had been helping take down a temporary stage in the park used for college basketball's Final Four festivities.</p><p>Besides CNN, the complex includes the Omni Hotel, a large atrium, food court, a book store and some souvenir shops. It's connected to Philips Arena, home of the NBA's Atlanta Hawks and NHL's Atlanta Thrashers. Nearby is the Georgia Dome, the home of the NFL's Atlanta Falcons and where college basketball's national championship game was played Monday night.</p><p>The CNN Center also is just across the street from Centennial Olympic Park, where a bomb exploded during the 1996 Summer Olympics, killing a woman and wounding more than 100 people.</p><p>Jacques Richard, 60, of Paris was part of a group touring the CNN studios when he heard the gunfire. He said the group was immediately brought down an elevator and dispersed. "We had our guide with us and everyone was calm," he said.</p><p>In the food court, Trina Johnson, 44, of Atlanta, was with her daughter on a family outing.</p><p>"All of a sudden we heard a big boom. We thought it was an explosion," she said. "We didn't see the gun. Everybody just started running."</p><p>Don Shields, manager of the Atlanta Braves Clubhouse store, which is just down the hall from where the shooting took place, said when he heard the "bang, bang, bang," he immediately yanked down the store's entrance gate and quickly escorted the store's two dozen customers at the time into a back room for their safety.</p><p>"I always said to myself I'm going go back there if anything happens," Shields said, referring to the back room. "Since 9/11, everyone has to think that way."</p><p>Soon afterward, CNN's own coverage of the shooting was being shown on large-screen televisions inside the atrium, near where the shooting had just taken place.</p><p>___</p><p>Associated Press Writers Harry R.
