Cincinnati campus officer shoots and kills unarmed black male

[Rotobeast]

If I were to speculate (keep that word in mind)........

I would say that she killed herself due to not being able to get out of jail, to start/continue (not sure if she had started, yet) her new job.
Given her supposed predisposition to depression and lack of any other outside stimulus (I cannot use the toilet without my cell phone), she likely obsessed on the issue and drove herself mad.
