APPENDIX B. DIVE FATALITY CASE REPORTS
entangled in his own line and his gas supply was exhausted. The autopsy disclosed changes
associated with drowning. Toxicology tests were positive for cocaine and cocaine metabolites.
The significance of the cocaine cannot be determined because of the decomposition that
occurred but it does indicate fairly recent use of the drug.
04-38 Double Fatality. Experienced technical and cave diver, obese with heart disease,
made a dive with buddy into a complex cave system using mixed gas, body found the next
day at 240 feet
Cause of Death: Drowning due to Insufficient Air Entrapment (cave)
This 38-year-old male was a very experienced technical diver with cave diving certification. He
and another experienced diver entered a complex cave system using mixed gas. When they did
not exit the water at the expected time, a person on shore summoned assistance and a search
was undertaken. The diver’s body was located the next day, at a depth of 240 ft (73 m). His gas
supply was exhausted. The autopsy disclosed changes associated with drowning, along with
obesity and left ventricular hypertrophy.
04-23 Poorly conditioned but experienced AOW diver with past medical history of seizures
and cocaine addiction, made night dive to collect game, separated from buddy and
entangled in anchor line, found that air was never turned on
Cause of Death: Drowning due to Insufficient Air due to Entrapment (anchor line)
This 33-year-old male was an experienced diver with advanced open-water certification. His past
medical history included seizures that required medication for control. This was due to a cocaine
addiction but according to reports he had been off medication and free of seizures for some time.
The planned dive was a night dive off a boat in order to collect lobsters. As the diver and his
buddy descended, the buddy saw a light on the bottom and swam toward it, thinking it was the
decedent. It turned out to be just the decedent’s light and weights. The buddy then saw the
decedent 10 fsw (3 msw) above him and entangled in the anchor line. The buddy could not
untangle the diver’s equipment from the line so he removed the diver’s buoyancy compensator
and brought the stricken diver to the surface. The diver was taken to a recompression chamber
where he was pronounced dead. When the tank was found, the pressure gauge read zero psi. An
evaluation of the diver’s equipment revealed that his air was turned off and that there was plenty
of air in the tank. The logical conclusion is that the air was initially turned on and for whatever
reason was turned off before the diver entered the water. The diver would have been able to take
a few breaths before there would have been no air in his hose. He also had integrated weights as
well as weights in the pockets of his buoyancy compensator, in addition to the weight belt he had
dropped. The autopsy revealed an obese diver with liver steatosis, a tongue contusion, and
changes associated with drowning.
B.6 Proximate Cause: Drowning / Various Causes
04-10 Diver with AOW certification, unknown experience, planned night dive but never
submerged, signaled to boat with light before lost consciousness
Cause of Death: Drowning
This 61-year-old male had advanced open-water certification but an unknown amount of diving
experience. He was making a night dive from a boat but he did not submerge with the rest of the
divers. The diver signaled back to the boat with his light before he lost consciousness. The diver
was pronounced dead at a local emergency room. The autopsy demonstrated changes consistent
