Final Crisis

The investigations into both deaths continue, and the heroes don't find many acceptable answers. Batman's investigation of one body is hindered by the rival investigation of the Alpha Lanterns, John Stewart's investigation of the first crime scene is hindered when he is attacked by a fellow Lantern, and Wally West and Jay Garrick's investigation into the second crime scene is hindered by the arrival of an ally not scene in years, who is not alone.
