The people behind
the precision.
Led by co-owners Derek Machens and Brian Meadows, Precision Analytics brings together analysts with extensive experience in major criminal investigations, detailed historical analysis, and presentations for court proceedings.
Our team
Experience earned
in complex cases.
Our team combines more than 50 years of law enforcement experience with 600+ hours of advanced cellular and geolocation training.
Across their careers, our analysts have worked hundreds of major criminal cases. Their experience spans homicide, robbery, carjacking, kidnapping, and murder-for-hire investigations, as well as complex organized crime and federal RICO cases.
We bring that investigative perspective to the detailed historical analysis and courtroom preparation we provide for prosecutors. Our analysts examine cellular and geolocation records, assess patterns of life, and bring timelines, communications, and other evidence together in clear, synchronized presentations.
Our analysts have prepared evidence presentations that have helped cases resolve through negotiated pleas and have testified as experts in state and federal courts. Prosecutors work with a team that understands how the evidence was developed, how it may be challenged, and how to explain it clearly.
Professional credentials
Our analysts’ backgrounds include advanced degrees in Criminal Justice, state and federal awards, and service as federally deputized Task Force Officers. Team members have also developed Missouri POST-approved courses on cellular technology and social media investigations.
Operational experience
Our team’s field experience includes cellular and vehicle location work in fugitive, missing-person, and violent crime investigations.
Derek Machens and Brian Meadows lead the firm, with additional analysts available for casework as needed. The assigned expert and relevant qualifications are confirmed for each engagement.
