ATLANTA – An ex-con who spent four years in prison for a fatal robbery in Florida will spend the rest of his life behind bars after being convicted Wednesday of killing his ex-girlfriend at the CNN headquarters complex last April.
Arthur Mann, 40, was convicted by a jury of murder, kidnapping, aggravated assault with a deadly weapon and several firearms possession charges in the slaying of 22-year-old Clara Riddles.
A judge then sentenced Mann to life in prison without parole, prosecution spokeswoman Lyn Vaughn said.
Prosecutors said 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 and wounded by a security guard.
The lunchtime shooting on April 3, 2007, created chaos at one of the city's most popular landmarks about 14 hours after the nearby Georgia Dome hosted the NCAA basketball championship game.
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 four.
