The Texas House Committee on Criminal Jurisprudence has issued an unprecedented subpoena for death row inmate Robert Roberson, who is scheduled for execution today for the alleged 2002 killing of his 2-year-old daughter, Nikki, in a case linked to shaken baby syndrome. The unanimous vote by the committee came after Roberson's clemency request was denied, amid growing concerns over the validity of the scientific evidence used in his conviction. Lawmakers and advocates have called for a 30-day reprieve to allow for further investigation into new medical and scientific evidence suggesting that Nikki's death was due to natural causes rather than abuse. This move has sparked a significant bipartisan effort to address perceived flaws in the justice system, particularly regarding the application of a 2013 law designed to rectify wrongful convictions based on discredited science. Legal experts have noted that the use of a subpoena in this context is highly unusual and raises questions about the separation of powers. As the execution looms, Roberson's legal team continues to argue for his innocence and the need for a thorough review of his case.
