At least two things are certain: He knew she was drowning, and he took his good ol' time getting to the surface for help.
I just read the accounts.
Shoot him!
I was wondering about what happened here, what the rest of the story was. The link helps.
As far as taking “his good ol’ time getting to the surface for help,” there is something that happens to a scuba diver if they don’t take their “good ol’ time getting to the surface.” It’s called the bends: http://scuba-diving.suite101.com/article.cfm/the_bends_in_scuba_diving
I’m not defending this guy, esp. with the info. on him cutting the flowers off her grave. However, it is clear to me that many here don’t know beans about scuba diving. (On the other hand, some do, for example the poster above who mentioned that if you aren’t looking, WWIII could be going off behind you and you wouldn’t notice — well, unless there were shock waves etc.)
