This case involves a female deputy who died in a boating accident during a training exercise in Michigan. The deputy frequently performed road and marine patrol. She was training on a lake with other deputies when she was ejected from a boat. Her life jacket became entangled in the boat propeller and she went underwater for several minutes. The deputy was rescued and resuscitation was attempted but failed. An expert in marine training was sought to opine on deputy marine training standards and protocols to ensure passengers are safe during training exercises.
