Marine Officers Dismissed After Mortar Explosion
HICKORY,--Three marine officers are being held responsible for an explosion that killed a Hickory Marine and several members of his unit.
Reports say 21-year-old Lance Corporal Mason Vanderwork and seven other Marines from Camp Lejeune died during a training exercise in Nevada in March.
Investigators haven't revealed what caused the explosion but say three officers have been removed from their jobs and will be reassigned.
The pentagon has suspended use of high explosive and mortar rounds until further notice.
