Robert Roberson, facing his third execution date for a 2002 death linked to shaken baby syndrome, maintains his innocence. His lawyers and supporters argue the conviction relied on outdated science and that his autism contributed to a wrongful conviction. A bipartisan group of lawmakers previously secured a last-minute stay. Prosecutors and some medical experts maintain the child died from abuse, while Roberson's defense asserts pneumonia was the cause. Supporters are again rallying for a reprieve.
