A court in Texas has halted the execution of Robert Roberson, whose 2003 murder conviction over the death of his 2-year-old daughter was based on the “shaken baby syndrome” theory, which has never been scientifically validated. On Thursday, a narrow 5-4 majority of Texas’s Court of Criminal Appeals granted Roberson’s request to stay his execution, citing a Texas law that allows for new trials in cases with flawed scientific evidence. The trial court that convicted Roberson will now consider whether he should be granted a new trial. Throughout his more than two decades on death row, Roberson has always maintained his innocence.
