From: ' Subject: RE: GS-I4 Justification --- UNCLASSIFIED Date: Fri, 10 Jan 2020 18:27:26 +0000 Importance: Normal Classification: UNCLASSIFIED Hi =, I've massaged the text that was submitted. Over the last year Mr. has exemplified an expert in Digital Video Recorder data recovery. He has completed 23 cases including high profile cases such as; the Epstein case, the Pensacola shooting case, and the Kealoha Corruption case. Mr. testified in the Kealoha corruption trial — case where the local police implicated a relative of the police chief for a crime (mailbox theft) which he did not commit; because they were having a family dispute. Mr. recovered the deleted video from 17 hard drives (3 different models of DVRs) and identified the metadata to include time and date stamps (this became important because the video in question was copied over the day after the police were served with a subpoena). Mr. testified in a Richmond Virginia Murder case where the prosecutor was about to reach a plea agreement for 5 years, after recovering the video of the murders they resulted in judgments of 40 years or more. Mr. prepared to testify in a NC Murder trial, but before he was called to testify the case pled out. Mr. has developed methods of DVR recovery by identifying the file structure and data to be recovered then he either; • Copies the data out and makes the files playable (carving) or • He creates a new file structure and copies the data into the file structure to play through the submitted DVR. (This is why he sometimes need the DVR in question) Mr. has collaborated with other law enforcement partners within the federal government and he keeps contact with the United States Secret Service, Department of Health & Human Services, and the Office of the Inspector General. (Mr. has made additional contacts through the Scientific Working Group — Digital Evidence). He also keeps in touch with Virginia State Forensic Lab and a New Jersey Police agen
