If you’re the perp, would you rather leave her body in her house or some place that could be traced to you?
Especially if the person who hired you wanted her to be found while he was out of town...
I’m guessing the person behind the killing didn’t want her body left at the house where the kids would find it.
Unless she just encountered a crazy stranger when she arrived home.
But who would take a body away in a hockey bag?
