FYI if anyone wants to know just how loud even a small caliber handgun sounds when fired check this out.
Yah even a .22lr makes a pretty noticeable bang. But I will say I have shot my .22L riffle right outside my back door and the wife didn't even hear it from inside and she was only our entry way and family room away. The tv was on and kids were playing in their toy room likely making some noise as well, so there were other relevant factors as well.
Now sound obviously does carry much better outside and I bet if I had asked my neighbors that were outside a 1/4 mile down the road, I'll guarantee they would say they heard it.
But my point is It's not always heard
I'm not sure it matters really bc I don't think there was evidence of a firearm being used inside the house. I think we would have seen evidence of a bullet hole etc if one was used in the bedroom and I think that would have been in the original AA.
But if there was one used a few things to keep in mind.
The bedroom was in the basement, sound wouldn't travel thru basement walls nearly as well as it would thru wood framed upper level exterior walls. Even upper level exterior walls have insulation etc. Additionally how many exterior walls, sections of exterior fencing, there are between the gun and the person that would be expected to hear it would be a significant factor too IMO
It was the middle of winter, no windows would likely be open hence harder for sound to get out and harder for neighbors to hear inside their homes.
Outside gun shot near sierra pines possibility
Same here assuming nobody was outside any of the near by houses (windows closed, winter) and there were no vehicles in close proximity at the time of a small caliber gun shot, It wouldn't surprise me to learn that nobody noticed it.
All just speculation as we don't even know for certain that a gun is even involved, per the AA it seems that there's a possibility of it but hopefully we learn more at the probable cause hearing.
