As an experienced diver and certified scuba instructor, Milton Floyd knew the dangers of surfacing too quickly. He also knew the potential risks of helping another diver in trouble.
"The rule is, if someone is in distress, you never make a second victim," his wife, C. J. Floyd, said Monday. "Milt knew that."
But on Saturday, Floyd and two experienced diving companions blew through decompression precautions while ascending from about 200 feet below the surface of Lake Wazee in west central Wisconsin.
Within hours of racing to the surface, Floyd, 60, of Minneapolis, was dead. So was James Jordan, 57, of Eagan, who had a heart attack while surfacing with Floyd.
The third diver, Milos Squires, 53, of Chaska, was treated for hours in a hyperbaric chamber at Hennepin County Medical Center and then released. The chamber, where Floyd also was treated, is used to eliminate the deadly nitrogen buildup in divers who surface too rapidly.
As the Jackson County Sheriff's Office sought to piece together what happened, investigators and medical experts are sure decompression illness brought on by the rapid ascent factored into the two deaths.
As Floyd's widow also looked for answers, she considered the possibility her husband bypassed decompression protocols because his friend Jordan was in trouble.
She has been analyzing the diving computer from his gear, seeking clues about what happened below the surface. She said the computer indicates her husband was making a normal ascent until something happened about 60 feet below the surface.
