Negligent homicide, involuntary manslaughter, or at the least wrongful death. I liken it to the gen manager of a chem plant in Houston who sent workers out without the proper training or PPE, resulting in their deaths. Criminal and civil penalties should apply.

Of course, the operative term you used is "had to be rescued". I don't believe anyone should be compelled to risk their health and safety in an attempt to save someone else. It is one thing to volunteer, even to get paid for that, because you can always refuse it, but does anyone really have to be rescued these days?

I nonehteless have great respect for those who go in harm's way to try and help others in need, even if the need is self-generated.

I would surely hope the DA would press charges. At least the family well ought to.
