Last year, Texas Gov. Rick Perry (R) admitted that he “never struggled . . . at all” with whether someone his state executed might have been innocent. Yet a new book written by Columbia Law Professor James Liebman shows that Carlos DeLuna, executed by Texas in 1989, was innocent. According to Liebman, DeLuna was wrongfully convicted and executed for the murder of Wanda Lopez following a botched investigation. DeLuna and the man believed to have committed the murder, Carlos Hernandez, looked so much alike that they were mistaken for each other in photographs by family members.
