Do you think a stranger would be apt to do this, or someone from the community/area?

"Do you think a stranger would be apt to do this, or someone from the community/area?"

It's difficult to speculate on that question.

On the one hand, locals would certainly come to mind first but IF it was a "professional hit" then professionals would naturally "case" the joint first. "Casing a joint" could sometimes take weeks.

Rebecca was a physical therapist. Wonder if she ever had a problem with one of her patients ?

Maybe someone was watching her, saw husband leave the house early as usual, thought he'd be gone a while. Perhaps Michael's return home startled him and he panicked . If she recognized the person it could explain why there was no sign of a forced entry.
