Just take a glance at her criminal record, job history, or that interview with her coworker, and it’s pretty apparent that she’s always been trash.
This wasn’t some mentally stable woman who suddenly went off the deep end. This was a volatile, self centered, ill tempered sociopath, who committed one of the worst crimes imaginable.
I’m not saying anyone could have predicted it would go this far, but it wouldn’t be hard to see her for what she was. Especially for those who spent any length of time with her.
And that’s the frustrating thing, this didn’t have to happen.
