A 37-year-old Mission Viejo man died after diving in Laguna Beach on Tuesday, according to Lt. Jason Kravetz.
A woman who lives above Totuava Beach called police at 1:10 p.m. to report two distressed divers. She said they were attempting to get ashore but were getting tossed around in the waves.
One diver made it to shore, got rid of his gear and jumped back into the water to rescue the other man, who was in full cardiac arrest when he was brought to shore.
Lt. Kravetz confirmed that the two men were brothers.
Police, fire and lifeguards attempted to resuscitate him. He was transported by helicopter to Mission Hospital in Mission Viejo, where he was pronounced dead.
