If he’s put to death, Robert Roberson III, who is autistic, will become the first person in the country to be executed in a “shaken baby syndrome” case.

A man whose execution was halted will testify at a legislative hearing about a “junk science” law in Texas that many say should have saved him long ago.

Just four days ago, Roberson was minutes away from being executed while a flurry of legal motions and appeals ended with the Texas Supreme Court issuing a stay. On Monday, he's set to testify to a state committee.

The Texas Attorney General’s Office swiftly appealed to the Court of Criminal Appeals, which overruled the lower court’s order and put execution back on track. But an appeal from the lawmakers to the Texas Supreme Court was the final say Thursday: The execution, for now, was off.
