John Trenary Joins SEARCH as Director of Digital Forensics Services

New title

SEARCH is pleased to announce that Mr. John Trenary has joined our management team as Director of Digital Forensics Services. In this role, John will direct SEARCH’s national program that offers comprehensive digital forensics services to local, state, and federal justice and public agencies. This includes investigations (computer, mobile, cloud) with a specialized focus on Medicare fraud.

“John is a recognized leader with deep knowledge and significant experience in digital forensics examinations and a commitment to finding justice for crime victims,” said SEARCH Executive Director David Roberts. “He leads a team of experienced examiners who work with agencies across the nation to support digital forensics investigations.”

John began his duties March 25. He recently retired after 25 years of service from the Linn County (OR) Sheriff’s Office, where he was a Deputy Sheriff, Cybercrimes Detective, and Digital Forensics Laboratory Manager. His last 10 years of experience involved conducting criminal investigations that focused on digital forensics analysis (computer, mobile, memory, cloud, network, data sets) and on investigations with technology as the nexus. He also frequently provided sworn expert witness testimony.

John is no stranger to SEARCH, having worked as a contractor since 2018, providing cybercrime and digital forensics training to justice agencies across the nation, authoring technical publications for law enforcement under auspices of the U.S. Department of Justice, and providing technical peer review expertise.

John is a member of the International Association of Computer Investigative Specialists (IACIS), and a former member of the U.S. Secret Service’s (USSS) National Computer Forensics Institute Technical Advisory Council, the Internet Crimes Against Children (ICAC) Task Force, the Linn/Benton Cybercrime Working Group, and the National White Collar Crime Center. The USSS recognized Mr. Trenary in 2022 and 2023 as a Top Forensic Examiner and in 2021 with the Significant Case Award. The Linn County Sheriff’s Office honored him in 2021 as Employee of the Year, and in 2018 and 2020 as the Detective Division Employee of the Year.

Mr. Trenary earned a Professional Science Master’s degree in Cybersecurity and a Graduate Certificate in Digital Forensics, both from the University of Rhode Island, and a master’s degree in Business Administration from the University of Phoenix. He is a Certified Forensic Computer Examiner (CFCE) through IACIS; he also earned the following Global Information Assurance Certifications (GIAC) through the SANS Institute: Certified Forensic Analyst (GCFA), Certified Forensic Examine (GCFE), iOS and macOS Examiner (GIME), and Advanced Smartphone Forensics (GASF).
