Texas Gov. Rick Perry may have to decide whether a death row inmate lives or dies.
The 34-year-old Thompson is set for lethal injection Thursday evening for his part in the fatal shooting of a Houston convenience store clerk.
He was not the triggerman when Mansoor Bhai Rahim Mohammed was gunned down 13 years ago during a robbery. But he was convicted under the Texas law of parties, which made him equally culpable for the slaying.
The shooter, Sammy Butler, received life in prison. Thompson, tried separately, got death.
Perry is not required to follow the board's recommendation.
