A Texas judge has blocked the execution of the first man to be put on death row in the US for murder charges related to “shaken baby syndrome”, less than two hours before the capital punishment was due to be carried out.
Robert Roberson, 57, was sentenced to death in 2003 for the death of his two-year-old daughter, Nikki Curtis, after a post-mortem examination concluded she died of injuries from abuse.
Roberson and his lawyers have long maintained the child died of complications from pneumonia.
Following his stay of execution, Roberson voiced his shock and thanked his supporters, US media reported.
The prisoner was due to be executed at 18:00 local time (23:00 GMT) on Thursday.
But only 90 minutes beforehand, a Travis County judge issued a temporary restraining order to stop it going ahead, so that Roberson could testify in a hearing at the state legislature next week.
The decision came after a panel of the Texas House of Representatives issued a highly unusual subpoena for Roberson late on Wednesday, hoping that authorities would have to send him to appear at a hearing on 21 October.
A bipartisan group of 86 Texas lawmakers, dozens of medical and scientific experts, attorneys and others – including best-selling author John Grisham and pro-death penalty Republicans – have all called for Roberson to be pardoned.
The group argued that the conviction was based on outdated science, before authorities gained a proper understanding of “shaken baby syndrome”.
“In Robert’s case there was no crime and yet we’re about to kill somebody for it in Texas,” Grisham told reporters in September.
Roberson’s lawyers have also argued that his autism – which was undiagnosed at the time of Nikki’s death – was used against him after police and medical staff became suspicious at the lack of emotion he displayed.
Autism can affect how a person communicates with others.
In a statement reported by the BBC’s US partner CBS News, Roberson gave his reaction to the judge’s intervention, praising God and thanking his supporters.
“He was shocked, to say the least,” Texas Department of Criminal Justice spokesperson Amanda Hernandez told the Associated Press.
