Ahead of tonight’s scheduled execution of Nathaniel Woods in Alabama, O.J. Simpson has weighed in on Twitter and questioned the fairness of the case.

Barring court intervention or a commutation from Gov. Kay Ivey, 43-year-old Woods is scheduled to die by lethal injection at 6 p.m. at Holman prison, which houses Alabama’s death row. Woods was sentenced to death for the 2004 shooting deaths of three Birmingham police officers.

Advocates have said Woods shouldn’t be executed because he wasn’t the trigger man. Kerry M. Spencer, the man convicted of firing the deadly shots, has also been sentenced to die but an execution date hasn’t been set.

Questions about the quality of Woods’ legal assistance and claims of police misconduct have been receiving attention in the weeks leading up to the execution, including in a recent story co-published by AL.com and The Appeal.

“Everyone deserves a fair trial and appeal,” O.J. Simpson wrote on Twitter this afternoon. “Come on Alabama do what’s right.”

Simpson, a former NFL star, was notoriously accused and acquitted in criminal court of the murders of his former wife, Nicole Brown Simpson, and her friend Ron Goldman. Simpson was found responsible for the deaths in a civil lawsuit.

Simpson is among multiple groups and advocates, including Martin Luther King III and celebrity Kim Kardashian West, who have asked for a halt to the execution.

“It’s just wrong,” Simpson said in a video on Twitter.
