I noticed in the timeline thread, we don't have times on the Pick Your Part trip to Hayward or on the bank trip. I've seen divergent news stories on the auto salvage trip, some saying "hours before" Hasanni went missing in the afternoon, some saying "that morning."
To me, these two pieces of information are important. Right now, what we know for sure is that if it occurred that day and LR is truly the only party with knowledge, he had roughly 8 1/2 hours (7 a.m. - 3:30 p.m.) to kill Hasanni, come up with a plan, make alibi trips (drive time being important + ATM time + yard time), and clean up or stage any evidence and handle body disposal. That's the window, of course, if he committed the crime right at 7:01 a.m. The more time we know was taken, the tighter the time window (and the closer the body would have to be).
For instance, if JC's story is correct, and supposing (though not likely) the second she left, Hasanni was hurt within 15 minutes. Even if he spent only half an hour planning, that's still 45 minutes. Add in even a 15 minute trip to the bank and a 20 minute trip to Hayward, and you've eliminated 1 hour 20 minutes from the timeline, taking you to 7 hours and 10 minutes. Add 5 minutes spent at an ATM and 10 minutes at the auto yard parking lot and you now have less than 7 hours.
Even if you eliminate care time for Aayliah (diapers, food, etc.), possible gas trip, shower, clean-up, preparation of body for transport, walking from car to exact dump site, and other variables, would this mean that Hasanni has to be within 3.5 hours of Roxie Terrace (or Hayward) if LR did it that day?
