It’s easy to walk away from work or your love life but a child. That’s hard to comprehend.It is unknown. RFG was a prosecutor and probably would have been aware of data security.
For all we know, RFG could have erased the drive, separated it from the laptop, tossed both, and planned to go into work on Monday and say that he lost it.
If RFG absence is voluntary (walkaway or suicide), the laptop is probably related. If this is homicide, it may not be.
