Richard Lee Tabler executed for 2004 Texas double killing in dispute with his strip club manager

A Texas man who killed his strip club manager and another man, then later prompted a massive lockdown of the state prison system when he used a cellphone smuggled onto death row to threaten a lawmaker, was executed Thursday night.

Richard Lee Tabler, 46, was given a lethal injection at the state penitentiary in Huntsville. The time of death was 6:38 p.m. CST, 15 minutes after a lethal dose of the powerful sedative pentobarbital was administered in his arms.

"There is not a day that goes by that I don't regret my actions," Tabler said, strapped to the death chamber gurney, looking at relatives of his victims who watched through a window a few feet away.
