Even if she knew there was danger, yes what were her options? The police cannot save her from a man obsessed with hurting her. A restraining order does not mean anything if a killer is determined.
We can see MM was clever about skirting the law, covering up. So MT may not have had enough to go to the police. Even if she had evidence that he broke into her home, are the police going to extradite him from Illinois? How long will it take? Even if he is arrested he gets an attorney and is out on bail. Etc etc.
MT had a family to think of. Her husband had to get to work each day. One child going to preschool perhaps. Another child, an infant needing a high level of care. She cannot just uproot them and go into hiding and disrupt their routines. And where does she go anyway? Moving from hotel to hotel? Not a good long term solution. Stay with her family and put them in danger as well? Disrupt their lives too. Not a good long term solution either.
Even if she could convince her husband to move away, he would have to go through a credentialing process in another state. And they would be away from MT's family, her support system. And MM would find her anyway.
Also it was the holidays, a lot going on. She may have thought, let's just get through the holidays. Not hit the panic button, give everyone a nice Christmas. I will deal with this in January.
Perhaps she may not have realized that time was of the essence, her ex was dramatically out of control due to career setbacks and possible drug abuse. So perhaps she minimized it due to lack of good up to date information.
I am a retired mental health professional. I am trying to explain the typical thought processes of women who are being abused/stalked, etc. And how they do not have a lot of good options.
Another member of this forum who has been abused and stalked, put it very well. The victim must also go through mental gymnastics and a cost benefit ratio on every decision.
