A judge granted a request to delay the execution of a man scheduled to become the first person in the U.S. put to death for a murder conviction tied to a diagnosis of shaken baby syndrome.

The Texas Supreme Court halted Thursday night’s scheduled execution of a man who would have become the first person in the U.S. put to death for a murder conviction tied to a diagnosis of shaken baby syndrome.

The late-night ruling to spare for now the life of Robert Roberson, who was convicted of killing his 2-year-old daughter in 2002, capped a flurry of last-ditch legal challenges and weeks of public pressure from both Republican and Democratic lawmakers who say he is innocent and was sent to death row based on flawed science.
