An ex-con who spent four years in prison for a fatal robbery was indicted Tuesday on murder charges in the fatal shooting two weeks ago at the CNN headquarters complex.

Prosecutors did not say whether they would seek the death penalty against Arthur Mann for the April 3 slaying of his ex-girlfriend, 22-year-old Clara Riddles. They plan to meet with her family within the next few weeks to discuss sentencing options.

Mann, 39, is charged in the indictment with murder, felony murder, kidnapping with bodily injury, aggravated assault with a deadly weapon, possession of a firearm during the commission of a felony and possession of a firearm by a convicted felon, according to the district attorney's office.

The indictment says Mann confronted Riddles at her job at a hotel attached to the CNN Center and dragged her by her hair to an escalator. When she tried to resist, he shot her twice, prosecutors said.

Riddles died at a hospital. Mann was shot by a security guard and has been recovering.

Records show Mann has an extensive criminal record, including convictions in Florida for car theft and sex with a minor. He also has a murder conviction in Florida for killing someone while committing a robbery, records show. He was sentenced to 10 years for the murder but served only four.

According to Riddles' employer and a police statement, Riddles lived in College Park, a suburb south of Atlanta. A police spokesman has said she had lived for a time with Mann in Fairburn but did not live with him at the time she was killed.

Prosecution spokeswoman Lyn Vaughn said she did not know if Mann, who is still in the hospital, had an attorney yet. A preliminary hearing is scheduled for Wednesday.
