A Texas judge has blocked the execution of Robert Roberson, the first man in the US sentenced to death over charges related to “shaken baby syndrome,” less than two hours before his scheduled execution.

Roberson, 57, was sentenced to death in 2003 for the death of his two-year-old daughter, Nikki Curtis, after an autopsy determined she died from abuse-related injuries. However, Roberson and his legal team have consistently maintained that the child died from complications of pneumonia.

Roberson was set to be executed at 6 p.m. local time (11 p.m. GMT) on Thursday, but a Travis County judge issued a temporary restraining order just 90 minutes before the execution. The ruling allows Roberson to testify in an upcoming state legislature hearing scheduled for next week.

The decision came after a Texas House of Representatives panel issued a rare subpoena for Roberson late Wednesday. The bipartisan group of lawmakers, along with medical experts, attorneys, and prominent figures like best-selling author John Grisham, argued that Roberson’s conviction relied on outdated science regarding shaken baby syndrome.

In addition to the flawed science, Roberson’s lawyers also contend that his undiagnosed autism was used against him during the investigation, as authorities misinterpreted his lack of emotional display as suspicious behavior.

In a statement reported by CBS News, Roberson expressed shock at the last-minute intervention, praising God and thanking his supporters for standing by him.
