A man convicted in the shooting death of a convenience store clerk became the 400th person to be executed in Texas since the state resumed capital punishment in 1982. Johnny Ray Conner, 32, asked for forgiveness repeatedly and expressed love to his family and his victim's family, who watched him through windows in the death chamber on Wednesday evening. "This is destiny. This is life. This is something Allah wants me to do," he said. "I'm not mad at you. When I get to the gates of heaven, I'm going to be waiting for you. Please forgive me." Conner was convicted in 1999 for fatally shooting Houston convenience store clerk Kathyanna Nguyen, 49, during an attempted robbery.
