I dived at that site two weeks before the accident. Visibility was very bad, about 1m and cleared up only below 20m where visibility was OK but no light, all pitch black. Not unusual there in summer with algae and rain. We had planned to practice free ascent, but then decided not to due to extremely bad visibility over a steep slope, and had a nice after-work dive to 35m instead. It's a steep slope down to 50m, a wall on one side with a big mirror installed at 32m for selfies. Popular spot, but definitely not the place to go for your very first cold water mountain lake dive.
The guide was sentenced because he left the victim at 36m. According to the expert witness the victim was overweighted but the guide could have easily inflated the victim's BC; there was no technical problem, the guide just didn't do it and went up alone.
Although they had paid the guide for the event, I don't think that it was relevant for this particular case. Any diver deserting his buddy in need for no reason would've been investigated for involuntary manslaughter. It's because team members agree to help each other and the victim accepted an elevated risk because of that agreement. (Whereas refusing to help a random stranger in need whom you met accidentally, is a mere crime of omission with lower penalty.) The qualification and experience of the defendant raises the bar on how much you can expect from him, and an instructor will be held to higher standards than a fresh OWD.
