There is a huge mistake in this reasoning! Time dilation goes to infinity at the center of the black hole - at the singularity, not at the event horizon! The event horizon could be millions of miles (many AUs) away from the singularity. Near the event horizon, her husband is likely to be falling rapidly into the black hole and is not going to be stuck indefinitely. So, it's Murder 1, immediately.

That is incorrect. The inside and outside of the black hole are causally disconnected. For someone who passes the event horizon the entire future history of the universe plays out above them as the universe warps down into a single beam of light as the black-ness engulfs you.

From the perspective of someone outside, nothing ever "crosses" the event horizon - it just slowly redshifts into darkness and appears to take infinity to "touch" the even horizon.

There is nothing "happening" inside of any black hole right now that has any corresponding time in the outside universe. From our perspective, it happens in the infinitely far future.

"For someone who passes the event horizon the entire future history of the universe plays out above them"

I believe this is only true if you have found a way of lingering with zero speed at the event horizon. If you are entering it at near light speed, as you likely would, you will be ingested as a part of "treadmill" containing yourself as well as all the light and will not see much of the future history.

Think of it this way: 1) the closer to the speed of light the bigger difference between your time frame and an external observer's. 2) at the speed of light the universe will age to infinity as you watch 3) inside the event horizon, even the speed of light is not enough to escape.

For an external observer you'll appear to slow down as you approach the event horizon. However feeding blackholes do increase is size obviously (or they would all be the same size), which may well save you from the (from an external perspective) an infinite descent.

No there isn't. As far as external observers are concerned, an object falling into a black hole takes an infinite amount of time to cross the event horizon. It vanishes from sight because its emissions get red-shifted beyond detection range, but in principle you could still see it however far in the future you care to go, "frozen" in place over the horizon, still approaching it asymptotically.

Not a physicist, but Wikipedia seems to disagree with this.
