Oh, my gosh. This is so tragic. All they time and energy and emotional investment, just gone. I know the feeling well, and it can also include rage over how unfair mother nature can be.
Putting up hot wire is a good start, but to be effective, it has to be mounted against a barrier so the bear can' just jump over or hope between wires. They must be invited to engage with the hot wire and you do that by baiting it with peanut butter. The bear has to contact the wire with nose or mouth since all other parts are well insulated.
Ask me anything about bears. I've had them in my house twice for destruction derbies and just last summer in my coop. I've never had a bear attack when the hot wire was activated. They've all been when the wire was off.
