Digital video recorder (DVR) and network video recorder (NVR) systems are everywhere — in businesses, homes, warehouses, parking lots, and along public roadways. When an incident becomes the subject of litigation, the surveillance footage captured by these systems can be the single most important piece of evidence in a case. But DVR evidence is also among the most fragile and most frequently mishandled digital evidence we encounter in our practice. The difference between foot

By Lance Sloves, CCE, CCPA | Computer Forensic Services, Inc. | Dallas, Texas A practical guide to collecting, processing, and loading ESI from computers, Office 365, OneDrive, Teams, and cell phones into a review platform — fast. If you're a litigation attorney staring down a two-week production deadline with ten custodians, each generating data across computers, email, cloud storage, Teams, and cell phones, you're looking at one of the most common yet operationally complex

By Lance Sloves, CCE | Computer Forensic Services, Inc. | Dallas, Texas When a case hinges on digital evidence — and increasingly, most cases do — the first and most critical step isn’t analysis. It’s collection. A forensic examination is only as good as the data behind it, and if that data isn’t collected properly, preserved defensibly, and documented thoroughly, even the most compelling findings can be challenged or excluded. At CFSI, we perform forensic data collections ac

By Lance Sloves, CCE | Computer Forensic Services, Inc. | Dallas, Texas When attorneys bring us a motor vehicle accident case, the first question is almost always the same: Was the driver on their phone? The answer rarely comes from witness testimony or cell carrier records alone. It comes from the phone itself. In a recent case involving a highway collision on SH-114 in the Dallas-Fort Worth Metroplex, our forensic examination of the at-fault driver’s iPhone told a story th

By Lance Sloves, CCE | Computer Forensic Services, Inc. | Dallas, Texas The short answer is: less time than you think. And in some cases, the clock started ticking the moment the driver picked up the phone after the crash. Cell phone evidence in trucking accident cases is among the most volatile categories of digital evidence an attorney will encounter. Unlike a paper document sitting in a filing cabinet, digital data on a smartphone is constantly being created, modified, and

By Lance Sloves, CCE | Computer Forensic Services, Inc. | Dallas, Texas In the last several years, cell phone evidence has become one of the single most decisive categories of evidence in commercial trucking litigation. When an 80,000-pound tractor-trailer collides with a passenger vehicle, the stakes are enormous, and proving or disproving driver distraction often determines the outcome. As a digital forensics examiner who has analyzed cell phones in hundreds of cases, I can

By Lance Sloves, CCE | Computer Forensic Services, Inc. | Dallas, Texas One of the most common mistakes we see in trucking accident litigation is the assumption that call detail records and a forensic cell phone extraction provide the same information. They do not. The difference between these two evidence sources can determine whether a distracted driving claim survives a motion to exclude or collapses under cross-examination. After more than two decades of performing cell p

In wrongful death litigation, understanding exactly what happened in the minutes leading up to a fatal accident can be the difference between justice and injustice. When a pedestrian is struck and killed by a commercial vehicle, questions immediately arise: Was the pedestrian distracted? Were they on their phone? Could they have avoided the collision? And critically — could the driver have seen them? In a recent case involving a fatal pedestrian accident in a North Texas resi

In personal injury litigation involving vehicle accidents, one of the most critical questions is often: Was the driver using their cell phone at the time of the collision? Call Detail Records (CDR) obtained from cellular carriers can provide powerful forensic evidence to answer that question — but only if they're properly interpreted. In a recent case involving a vehicle accident in Southeast Texas, our firm was retained to analyze AT&T Call Detail Records belonging to a def

By Lance Sloves, CCE | Computer Forensic Services, Inc. On September 6, 2018, off-duty Dallas Police Officer Amber Guyger entered the apartment of 26-year-old Botham Jean — one floor directly above her own at the South Side Flats complex — and fatally shot him, claiming she believed he was an intruder in her home. What followed became one of the most closely watched murder trials in Dallas County history, a case that drew national attention and raised profound questions about

By Lance Sloves, CCE, CCME | Computer Forensic Services, Inc. In digital forensics, there's a critical difference between observing that something could have happened and proving that it did happen. That distinction was at the heart of a custody case that went all the way to the Fifth District Court of Appeals in Dallas — and the appellate court's 2022 opinion serves as a textbook example of why forensic testing matters.
