In a documentary about the gun massacre at a cinema in Aurora, Colorado, presenter Amal Fashanu is shown the application form that suspect James Holmes submitted when he tried to join a gun club in the weeks before the attack.
The owner of Lead Valley Range, Glen Rotkovich told Fashanu: "This is the actual application that I received from him, with his name, address and all the general information on it and his parents' address in San Diego."
