From AP:
A Texas man who could be the first person in the U.S. executed for a murder conviction tied to a diagnosis of shaken baby syndrome is facing a lethal injection Thursday evening amid assertions by his attorneys and a diverse coalition of supporters who say he’s innocent and was convicted on faulty scientific evidence.
Robert Roberson waited to hear whether his execution might be stopped by either Gov. Greg Abbott or the U.S. Supreme Court—his last two avenues for a stay. He is scheduled to receive a lethal injection at the state penitentiary in Huntsville.
