The family obviously wants it because the family wants answers, as they have been stating for weeks.
The fact that SDCSD is retaining possession of the phone, under the guise of "examining" it with suddenly new software that was unavailable on September 2, when RZ's death was officially declared a *suicide* and after the case was legally closed with so-called "iron clad" scientific evidence - well, it gives one pause for thought.
I, for one, will NOT apologize for being suspicious.
The family hasn't made any official request as far as I know. I doubt LE or any court will just hand a piece of property over without a legal document requesting it.
