This is the SW for the AT&T air card Merritt was in posession of at the time of the murders.
As of this warrant it appears that investigators did not know where Charles Merritt was when he accessed Joey’s QB account. Did they not ask him?
The dates as to when the McStay computer was accessed from within the home conflict with the dates given in the preliminary hearing.
This is Joey’s office where his desktop computer lived. How could someone freshly covered in blood enter this room and go to work on the computer?
