A 63 year old diver has died in a Labor Day incident at Lake Tahoe.The crew of Douglas County’s Marine 9 found the man on a diving boat, being given CPR. He was taken to the pier, where Tahoe-Douglas Fire Department paramedics continued to try to get a response, but he was pronounced dead. The man was diving with two friends off Glenbrook at the wreckage of the SS Tahoe in about 360 feet of water. Investigators say he and his companions are experienced divers and had completed a similar dive at the same wreckage the day before. But Monday, he made an emergency ascent to the surface, and when he reached the surface, he was unconscious.
