DA calls expert who extracted Cohen's cellphone data
Prosecutors have called their next witness: Douglas Daus, who works for the lab that processes devices for the Manhattan district attorney's office.
Daus works as an analyst in the unit of the Manhattan DA's office that handles intake and processing of electronic devices, such as a cell phone seized pursuant to a search warrant. Daus said the unit creates "extractions" of the devices, which are copies of the devices called a Cellebrite or GreyKey report.
The extraction contain "anything that is normally on a phone," according to Daus, including text messages, contacts, call history, and software.
The extraction also includes metadata, which provides a deeper record of when, where, and how a device was used.
For the Trump case, Daus conducted an analysis of two of Michael Cohen's phones -- an iPhone 6S and iPhone 7.
Daus said Cohen consented to the analysis of the devices.
