A Texas Supreme Court ruling has again cleared the way for the execution of Robert Roberson, who would become the first person in the U.S. to be put to death over a murder conviction tied to a case of shaken baby syndrome, a diagnosis that some medical experts have questioned.
Roberson was convicted of killing his 2-year-old daughter in 2003 and had been slated to die by lethal injection on Oct. 17. But the execution was halted after a bipartisan group of Texas lawmakers, including some who believe Roberson is innocent, issued a last-ditch subpoena ordering Roberson to testify at the Capitol days after his execution date.
