First, my sympathies to maxaroad & family for their tragic losses.
And then some first impressions I have about this case: The throwing of the brick, especially since robbery doesn't seem to be the motive and it would be obvious people were home (car in front, maybe lights on?), sounds to me like something done out of extreme, uncontrollable anger. It seems like it was done more to show how angry the perpetrator was, and not so much as a way to get in the house.
The article said that Ann and her husband hadn't lived in town long. Is there something connected to the place where they used to live? I'm just considering whether someone connected to their life in their old town saw the obituary and found where they now lived that way. That's another reason why robbery doesn't make sense; if a person saw the obit with the time of the wake and wanted to rob the house, they'd have done it while the wake was going on and not afterwards. But I can't imagine what kind of situation where they used to live might prompt such a violent killing.
The news report that they didn't live there long was wrong. They were there for at least the 20 years I knew them.
