Firefighters salute during a memorial service for fallen Houston firefighters Wednesday, June 5, 2013, in Houston. Four firefighters searching for people they thought might be trapped in a blazing Houston motel and restaurant last Friday were killed when part of the structure collapsed and ensnared them. Killed in the fire when the motel structure collapsed were Capt. Matthew Renaud, 35, engineer operator Robert Bebee, 41, firefighter Robert Garner, 29, and Anne Sullivan, 24, a probationary firefighter who had graduated in April from the Houston Fire Department Academy.
