The impending execution of Robert Roberson, a Texas inmate set to be the first in the U.S. executed over a shaken baby syndrome conviction, faces significant scrutiny. Just a day before his execution, a state committee made a historic decision to subpoena Roberson to testify, raising questions about the legal proceedings surrounding his case. Despite last-minute appeals and a growing chorus of support advocating for his clemency, the Texas Board of Pardons and Paroles denied his request, asserting that the conviction would stand. Leading voices, including author John Grisham, have criticized the Texas judicial system for its handling of the case. With doubts lingering over the validity of shaken baby syndrome as a cause of death and a controversial diagnosis being put to the test, Texas lawmakers are stepping in with unprecedented measures to potentially delay the execution. As the hours tick down, the debate continues over whether Roberson is truly guilty of the crime for which he is set to be executed.
