A bit pointless but a few things in that.
Firstly, I genuinely don’t think they have much of a clue. The chief was quite open about that numerous times. I think they did the press conference to keep communication going but seem no further forward.
Only interesting areas of substance to me:
They still think it’s targeted. That’s quite relevant because by now they also have all of the expert views behind the scenes. Suggests that the FBI, behavioural analysts etc… also have seen enough to believe this was not a random stranger killing. I put more emphasis on that now.
Big key key bit of info was that they were ALL believed to be asleep when killed. Blows apart a few theories on this board that Ethan and Xena were only harmed as they came across the perpetrator/were witnesses.
it also begs the question in that case why were the other two left alone?
So only key info for me out of that is a targeted killing of 4 individuals where all 4 were asleep, offered no threat or risk of exposure of the crime. So what’s the key there. Is there a common factor across the 4 whilst they were all deliberately targeted. I see no other reason why the killer would seek out all 4 unless there was a reason to do so if it wasn’t a case that some were killed only to cover up any evidence.
