Dad was open water certified only, and the kid had 0 scuba training/certifications. The dad never should have been in a cave and he certainly shouldn't have had his kid in any cave let alone in the Eagles Nest system. They were diving on straight air with MD of 233ft on their computers when the bodies were found. The kid was found on the ceiling of the ballroom at around 76 ft back gas empty on doubles, dad was found in 100+ ft. With proper training they would have realized that their gas was poison at that depth. The dad would/should have been charged with manslaughter had he not expired in the system. caves are no joke and the Nest is the Grand Canyon / Mt Everest of systems. Stupid and senseless on the dads part, he led that kid to his grave. Now we may all lose the ability to explore the Nest, it was taken away before, and it may very well be taken away again.
