(AP) — Gov. Rick Snyder has ordered that flags be lowered to honor three Michigan Marines who were killed in a Black Hawk helicopter crash off the coast of Florida during a training mission this month. Staff Sergeants Marcus Bawol of Warren, Trevor Blaylock of Lake Orion and Andrew Seif of Holland were among seven Marines and four Army soldiers killed March 10 when the helicopter crashed in a nighttime training exercise in dense fog.
