A Texas appeals court has ordered a halt to a district court’s inquiry into whether Cameron Todd Willingham, executed in 2004 for setting a 1992 fire that killed his three daughters, was innocent. The stay was sought by Navarro County District Attorney R. Lowell Thompson. It’s merely the latest attempt by Texas officials (Thompson’s office prosecuted Willingham), including Texas Gov. Rick Perry, to stave off any formal inquiry into Willingham’s execution.
