AUSTIN, Texas (AP) — A Texas man who murdered his strip club manager and another man, then later prompted a massive lockdown of the state prison system when he used a cellphone smuggled into death row to threaten a lawmaker, was scheduled to be executed Thursday. Richard Lee Tabler, 46, would be the second inmate executed in Texas in a little over a week, with two more scheduled by the end of April. He's set to receive a lethal injection at the state penitentiary in Huntsville.
