About

Enrique Santos, an investigative analyst with the U.S. Attorney's Office, testified on Day 21 about forensic work performed on three phones attributed to Casandra Ventura. He described full file-system extractions, recovery of some deleted records, and integrity-checking procedures, including the use of hash values.

Santos also explained how Cellebrite reports can present digital material differently from the underlying data. His testimony addressed participant names, timestamps, emojis, audio links, screenshot metadata, and the possibility that deleted messages may have missing or corrupted fields in report outputs.

On cross-examination, defense counsel questioned him about recovered deleted WhatsApp messages, the use of different forensic-analysis tools, and a screenshot's capture date. Santos said deleted data can remain hidden until overwritten and gave a qualified assessment that a capture date best reflects when an image was captured or screenshotted, rather than necessarily when the underlying conversation occurred. After he was excused, the Court admitted Government Exhibit 1309 and the exhibits listed in Government Exhibit 1503.
