As snow falls, a line of Great Falls police officers stand at attention and salute in remembrance of nurse Darcy Dengel outside the Central Assembly of God Church in Great Falls, Mont., on Monday, Feb. 12, 2007. Dengel, a flight nurse, was killed last week near Belgrade, Mont., when a Benefis Mercy Flight air ambulance crashed with her onboard. Dengel was engaged to Great Falls police officer Rob Beall. The pilot and a paramedic also died in the crash.
