Thanks for helping me out on this. I know I'm not up on everything.
BBM - it's possible the timing could be narrowed to somewhere between 8 pm - 11pm (to 1 am)? Allison's Mom talked to her at 8 and dad tried to text at 11pm. When did the sister talk to her to hear she booted the BF out?
If they have surveillance video for 1 am, did they eliminate the BF? One article said they couldn't eliminate that it was someone she knew, but that's not saying much.
Are they thinking someone could have been int he house for two hours (11pm or before to 1am)?
Your guess about the time is about as good as mine, even with the ever-changing news reports and police leaks and community meetings.
About the sister's report of Allison booting Alex out of the house - we don't know where she heard this. We don't know if Alex told her this or if Allison told her parents this and they told the sister. Or if Alex told the parents.
I think that Minnesota is on Central Time and so the time difference at that time (before DST kicked in) would have been one hour. So if her mom spoke with her about 8 pm her time it would have been 7 pm AZ time. If her dad texted her at 11 pm it would have been 10 pm AZ time.
Everyone who knew her states she never had her phone off. So I suppose we can assume that sometime after she spoke with her mom at 7 pm her phone was disabled in some way. I don't know what prevents a text message from going through. I have an iPhone and even if I turn my phone off text messages will still go through. Of course I don't get them or read them until I turn my phone back on. That part is a bit of a mystery to me. In spite of what her friends and family said, it is still possible that Allison might have turned off her phone for a while. So, it's difficult to pinpoint exactly when the perp might have arrived and departed based on calls or texts to her cell phone. At some point I do feel pretty certain that the killer did disable it, for obvious reasons.
I don't know how they have eliminated the BF as a suspect, but I have read and "heard" that they have.
I think it is doubtful Allison would have let someone come in her house that she didn't know at a late hour.
Based on the times, etc. I'm thinking the killer might have arrived as early as 8 or 9 pm AZ time and departed at 1 AM as stated by LE. And again, I am going back to her not letting anyone in way late so I'm assuming those times from when she spoke to her mom and then her dad's text didn't go through at ten pm.
I'm thinking she let them in because she knew them. They were there for awhile. An argument ensued. A terrible struggle. She was killed. He tried to destroy the evidence. He couldn't. He finally panicked and left.
This is again...pure conjecture. I have no crystal ball or inside information about who killed her or the manner in which she died or the times.
IMO
