Regarding the victims being targeted, I think “targeted” can mean a number of things, some of which introduce more risk to the community than others.Still catching up but wanted to park my thoughts :
JUST MY OPINION.
I am not sure I completely buy the Targeted theory, I think it is possible perp just didn't finish what he/she was doing.
I think statements were made too early in this case and I understand the feelings of families that things are not moving as quickly as they hope.
I agree with those that people should perceive a risk to safety is out there.
I think entry was gained through an unlocked door or even a window I can tell you even in cold I sleep with a window cracked I just like the crisp fresh air and I hate heaters.
Questions I have that make little sense lol, was there a fire pit outside, I could see them enjoying that area off the kitchen by a fire pit and maybe being in and out and not realizing the door was ajar or unlocked.
I think as details emerge, much more will fall into place.
For example, someone might target an individual person like an ex or a supervisor or a celebrity or public figure. Someone might target a couple people or a small group such as an ex and their new partner or their spouse and their kids or their classmates. Someone might target all those they’ve ever felt slighted by or hold grudges against (can be few or many). Someone might target what they perceive to be certain types or classes of people like “Staceys and Chads” or “sorority girls” (Elliot Rodgers type). Of course violent crimes against people of specific races, ethnicities, religions, sexual orientations and gender identities are sometimes targeted. The broader these categories get, the less comfortable I’d feel with the assertion that the community at large is not as risk.
Unless police believe it was targeted in a very narrow way, such as a disgruntled ex targeting an individual or a couple, I would feel very fearful in that community. And even if narrowly targeted, it’s scary enough to know someone capable of that degree of violence may be within the community.
