Oct. 16 (UPI) -- A Texas man could become the first person executed over a conviction case based on shaken baby syndrome even though a detective who helped set those wheels in motion now says he is innocent. The Anderson County District Court on Tuesday denied Robert Roberson's motion to stop his execution warrant for the 2002 death of his 2-year-old daughter, allowing his planned Thursday execution in Huntsville, Texas to move forward.
