Ok - so that would put her at home on night of 15-16th. Still interesting. Could that mean home on the 27th too then? She had to get those groceries that Tony saw from somewhere.
That night really is interesting, though. She's home all night she has an 80-minute conversation with AL @ 11:54pm, and then there is a TON of texts back and forth between the 2 of them until 3am.
At 3:00am AL calls her back and they speak again for 15 minutes.
She sends him one last text at 3:30 am and then there is nothing.
At 7:45 am on the 16th she tries to call the "7686" number and a "4909" number tries to call her, but there is no timed conversation, nor is there a cell tower ping.
She sends a text to AL @ 8:46am, and then he finally calls her back @ 11:47am, and they talk for 19 minutes.
There has to be something to the long call and the flurry of texts overnight.
