Lifeguards were called to La Jolla Shores Saturday morning to rescue a diver who suffered a serious medical condition while out in the water, authorities confirmed.
Lifeguard officials said the 50-year-old male diver was out on a group dive at around 8:30 a.m. when he began having difficulty breathing. Emergency crews pulled him from the water.
He was given CPR and transported to Scripps Memorial Hospital La Jolla in serious condition. He died a short time later, San Diego police confirmed.
Further details about what lead to the diver's distress and death were not immediately released. The Medical Examiner will determine the man's cause of death at a later time.
An investigation is underway. Authorities said they’re not sure if the diver’s condition was related to scuba diving or the result of some unrelated, pre-existing medical condition.
The Medical Examiner's office later identified the diver as San Diego resident Richard Reichert.
