This is NOT a neighborhood for a woman to stroll alone at 3 am.
In Austin sexual assault and rape of men is known to individuals that work the rape crisis centers. In Brownsville the disappearance of Americans in general, but specifically women, is all too common.
I say take care of your business during the waking hours.
But hey, just as people won't choose their friends wisely neither will they let someone tell them they can't be out at 4 AM.
"This is NOT a neighborhood for a woman to stroll alone at 3 am."
She's no doubt very "smart" what with being a graduate student, etc.
But I have heard that alcohol is a mind altering substance. And I have also heard that the first effect of drinking alcohol is loss of inhibition, distorted judgement, etc.
So I suppose it was possible that earlier, before drinking she might say she wouldn't walk around this neighborhood at 3:00 AM.
But she apparently did, after her mental abilities were changed.
It is even possible the person/people that raped and murdered her were drinking or drugging.
Lesson. She was obviously innocent. And the killer is evil.
Leave out the alcohol and she has a taxi ride home, perhaps a hangover.
Add alcohol. She is brutally murdered.
