Atlanta ? A domestic dispute erupted in gunfire at CNN’s headquarters complex Tuesday, killing a woman and critically wounding the ex-boyfriend who pulled a gun on her, authorities said.

The man and woman were arguing near the main entrance of the complex when the man shot her, police officer James Polite said. The armed man was then shot by a CNN security guard.

The woman, who checked and stocked honor bars at a hotel attached to CNN Center, was Clara Riddles, 22, of College Park, said Caryn Kboudi, a spokeswoman for the Texas-based Omni Hotel chain.

She was pronounced dead on arrival at Grady Hospital, said hospital spokeswoman Denise Simpson. Her ex-boyfriend, identified as Arthur Mann, in his late 30s, was in stable condition. He is being charged with murder, Polite said.

Soon after the shooting, CNN coverage of it was being shown on large-screen televisions inside the atrium, near where the shooting had taken place.
