A civilian contractor who worked with the Navy’s marine mammal program died during a nighttime diving exercise in the San Diego Bay on Monday.
Coll Perske, 29, was taking part in an exercise near the boat launch at Naval Air Station North Island when he did not resurface, according to the San Diego County Medical Examiner’s office.
The ME said co-workers helped Perske to the surface and performed CPR. Paramedics arrived and transported him to the UC San Diego Medical Center, where he was pronounced dead.
