Robert Roberson, who had been set to be the first person in the U.S. to be put to death for a murder conviction tied to a diagnosis of shaken baby syndrome, had his execution delayed after a dramatic few hours of legal wrangling among three different Texas courts.

Robert Roberson, a condemned man whose execution was halted, is expected to appear in person Monday at a legislative hearing in Austin, Texas.

Questions remain over what happens next after the execution of Robert Roberson was temporarily halted by the state Supreme Court on Thursday.

Roberson, 57, had been set to become the first person in the country to be put to death for a murder conviction tied to a diagnosis of shaken baby syndrome.
