About

Called by the government on Day 7, Stephen Flatley, an FBI digital-forensics examiner, described imaging Government Exhibit 54, preserving the original drive, and using hash comparison to verify the forensic image. He identified registry information, emails, and Word documents recovered from the drive, including documents stored in the Ghislaine user's documents folder and metadata listing gmax as author or last saver for certain records.

On cross-examination, defense counsel questioned the source and history of the cloned drive and the limits of the document metadata. Flatley said he did not know who created the documents, where the computer was located, who had access to it, or why a different hard drive had been copied. He explained that Word author and date fields may be populated from account settings or the computer system.

On redirect, Flatley testified that the emails he reviewed from Government Exhibit 54 were from the gmax1@mindspring.com account. On recross, he agreed that an installed email client may refresh from its server whenever a computer connects to the internet.
