there is speculation, but it was the Judge, Judge Stephens that Hinted the phone was owned by a third party in open court - and that there are privacy issues.
If that phone is not owned by a relative, I am sure that LE would look at that like aliases. Honest people do not need aliases either.
The phone supports E911. 360 hours of standby time.
Audiovox sold out to another company and the model became CDM9900, but verizon still called it the VX9900.
I think this is the phone listed as VX9900 on the warrant:
