Fat, tattooed, and scarred

"Questions emerge over police handling of Toulouse, France killings" by Alex Lantier (my emphasis in red):

"Heisbourg also raised questions about Merah’s training as a gunman, apparently acquired during a couple of trips to Afghanistan and Pakistan, though he spent most of his time working as a mechanic: “This ‘lone wolf’ acted in ways the most experienced mafiosi do not dare attempt. He ran his operation himself, and carried out the killings with an unprecedented degree of cold calculation and absence of hysteria. Even the September 11 terrorists were more unnerved. He has therefore received absolutely first-rate training. Who trained him and how?”
Indeed, some questions remain as to whether Merah in fact was the killer. He did not resemble the description given by witnesses at the Montauban shooting, who spoke of a corpulent figure with tattoos and a scar on the left cheek. By contrast, Merah was thin and had no facial markings."
