A diver attempting a world record found the body of another diver that had been missing for 10 years. He died trying to recover it!

In October 2004, 50-year-old David Shaw ventured into Bushman's Hole, the third deepest freshwater cave in the world.

Only two men before Shaw had reached the depth and survived. He was about 800 feet down and sweeping his high-powered flashlight around him when he made a shocking discovery.

Shaw found the body of a diver that had attempted this same dive 10 years ago, Deon Dreyer. Dreyer, a 20-year-old South African, had descended into Bushman's and blacked out.

His body was skeletal from sitting in the water for a decade and his tank was stuck in the mud and debris around him. Shaw tried to move him, believing that he should return to the body to Dreyer's parents, but he couldn't do so.

He continued on his dive but vowed to return another day for Dreyer's body. It became his personal mission. He told Dreyer's parents that he would recover their son, he trained, he planned and enlisted help.

Tragically, when Shaw finally went down into Bushman's to make the recovery, things went wrong and he too lost his life.
