How about not going into a bear's territory to begin with? There is the reasoning that animals are only threatening when threatened. Or if you are in their territory. I bet a lot of people would be angry or attack if a stranger was walking through their backyard making a lot of noise.
Anyway, the elevator story. I can't find a known site but according to a few, they were married for 5 years. So I imagine / guess that she wanted a divorce. Perhaps was cheating. Just like when you move, you know where you are going. That's what the majority of people in relationships do. Which is the wrong thing to do and why there is violence. The average man or woman for that matter isn't going to get aggressive for no reason.
The sites say the guy got 31 years. And that the wife might have been dead before the fall. Which is good or bad depending on how you look at being strangled to death by your husband. No one is jumping from the 4th floor to get away from their husband no matter how much they want a divorce. If you look at the video, she seems to be pushing for a lower floor. Maybe to get to the lobby and possible doorman. She didn't want to get to the apartment. She probably thought she could beat him to the elevator.
I can't find pictures of the apartment. But if it was an underground garage with a gate. Then the elevator was probably her only hope. As the garage remote would probably be in the car. And I guess she couldn't make the stairway. Either way, as the lawyers say, divorces are the worst cases to deal with.
Another elevator one that is also like a horror movie in how he just drops the body.
I need to stop looking at this stuff. In a horror movie is one thing. In real life is crazy.
