Dreyer's father, Theo (who owns a business that sells and services two-way radios) and mother, Marie, raised him in the town of Vereeniging, about 35 miles south of Johannesburg.
He was helping a team, assembled by Nuno Gomes, set up conditions for a deep technical dive scheduled to take place later that week.
[2][1] Two weeks after Dreyer's death, Theo hired a small, remotely operated sub used by the De Beers mining company.
[1] Dreyer's parents erected a plaque on a rock wall above the Bushman's Hole entry pool, in memory of their son.
Shaw's close friend and support diver, Don Shirley, also nearly died and was left with permanent damage that has impaired his balance.
