- Nationwide Digital Forensic & Cyber Investigation Services
Robbery prosecutions combine eyewitness identification with video and a phone timeline. Digital evidence is the part that can be measured, and measurement frequently narrows the case.
In a robbery case digital forensics tests identification, presence and the money trail. Store and transit surveillance is usually too compressed and too low resolution to identify anyone, and that limit can be measured. Carrier records place a handset in a sector, not at a counter. Payment application records show transfers, not purpose. Independent review documents each limit and rebuilds the timeline from source artifacts rather than from a summary.
The typical robbery file contains a short surveillance clip, an identification, a phone extraction summary and sometimes a payment application screenshot. Presented together they feel mutually reinforcing. Examined separately, each one has a specific and often severe limitation that the file never states.
Surveillance systems in retail and transit environments record at low resolution and low frame rate over long retention windows, and the copy produced to the defense is frequently a re encode. A phone extraction summary lists artifacts without stating acquisition level or time zone. A payment screenshot shows a transfer without the account history, device attribution or the surrounding transactions that explain it. Each gap is testable, and testing frequently changes the weight of the whole.
Independent review measures what the video can support, reconstructs device activity artifact by artifact with a stated clock, maps carrier records as coverage, and rebuilds financial application activity from full account exports rather than screenshots.
// Excerpt, device examination summary Acquisition level: not stated Hash verification: not recorded Time zone of report: not stated Artifacts listed: selected keywords only Raw image produced to defense: no Cloud accounts identified: none
A summary without acquisition level, hashing or time zone cannot be evaluated, and every missing line is a discovery request.
| Question | Short answer |
|---|---|
| Can store video identify my client? | Often not. Effective resolution on the subject and frame rate set measurable limits. |
| Does the phone place my client at the store? | It can place a device in a sector coverage area. That is not a street address. |
| Do payment app records prove proceeds? | They prove a transfer occurred. Purpose, control and source require additional proof. |
| Can a screenshot be authenticated? | Only weakly. Native exports with account and device metadata are far stronger and should be demanded. |
| Are multiple defendants' phones useful? | Very. Comparing devices frequently contradicts the asserted roles and movements. |
| Does deleted data recovery help? | Sometimes. It depends heavily on device, operating system version and acquisition level. |
| Is the state's report testable? | Yes. Acquisition level, hashing, tool version and time zone handling are all subject to audit. |
A single transfer looks like proceeds. The same transfer inside a four year pattern with the same counterparty looks ordinary.
The number of pixels actually covering the subject in the frame, which sets a hard ceiling on identification regardless of enhancement.
The variable geographic area served by an antenna sector. Coverage overlaps heavily in dense retail corridors and does not resolve to a storefront.
A record produced directly by the platform in its own format with account, device and timing metadata, as opposed to a screenshot.
Whether the extraction was logical, file system or full physical. The level defines the outer bound of what any report can contain.
Comparison of timelines, communications and artifacts across multiple defendants' devices to test asserted roles and coordination.
| Parameter | Measured | Requirement |
|---|---|---|
| Subject pixel height | 44 px | Substantially higher |
| Frame rate | 6 fps | Higher for motion detail |
| Face pixels between eyes | under 10 | Insufficient |
| Lighting | Mixed, backlit | Controlled |
| Compression | Heavy, blocking visible | Artifacts present |
Measurements replace argument. When the numbers fall below the requirement, the opinion follows from the numbers.
Sources that carry their own verifiable metadata outperform sources that require interpretation.
We measure effective subject resolution, frame rate, exposure and motion blur, then state precisely what identification the media can and cannot support. Where only a re encoded copy exists, we document what the re encode destroyed and demand the original.
The phone timeline is rebuilt from the extraction with each entry traced to a source artifact and a stated clock. Background writes, application syncs and duplicated entries are separated from genuine user activity.
Call detail records are analyzed as network engineering data and mapped as sector coverage with stated uncertainty. In dense commercial areas the serving sector routinely spans many businesses and several blocks.
Screenshots are replaced with native account exports where obtainable. Full transaction history, device attribution, account creation records and surrounding transfers frequently give a transaction an ordinary explanation.
Where several devices exist we compare communications, activity timing and movement artifacts across them. Coordination asserted in statements often has no support in the device record, and sometimes the record contradicts it directly.
We document acquisition level, hash verification, chain of custody, tool and version, time zone declaration and whether conclusions trace to underlying artifacts, then convert every gap into a discovery request or a cross examination line.
Once each entry is traced and the clocks are stated, the reinforcing narrative separates into independent and much weaker parts.

Each unchecked line is a motion, a cross examination question, or both.

Retained through counsel so the work stays inside the attorney work product framework.
The acquisition level is the ceiling on every conclusion in the report. Support varies by device and operating system version.
We report what the evidence supports and never speculate about content that no longer exists.
We work as independent digital forensic experts for defense counsel in robbery and armed robbery matters nationwide, including video limitation analysis, device examination and testimony.
Elite Digital Forensics is an independent digital forensic firm serving attorneys and their clients nationwide. Our examiners include former law enforcement forensic examiners and court qualified expert witnesses who work on criminal defense, civil litigation and corporate matters. We do not provide legal representation. We provide defense aligned forensic review, documented findings and testimony grounded in what the evidence supports.
Scope and schedule are set with counsel before work begins.
Send us the media, the extraction report and the discovery index. We will measure what the video supports and rebuild the device timeline from the source artifacts.

We measure the pixels covering the subject, the frame rate, the exposure and the motion blur, and compare those parameters against what is required for any identification opinion. When the media falls below that threshold, the limitation is stated with its measurements.
Carrier records identify the antenna sector that served a connection. In a commercial corridor that sector commonly covers many buildings and several blocks, and the network selects sectors for engineering reasons including load and interference. Anything presented as a point location should be treated as an interpretation, not a measurement.
The native account export from the platform rather than a screenshot, including full transaction history, account creation data, linked devices, IP session logs and any dispute records. Those elements allow authentication and frequently place the transaction inside an ordinary pattern of activity.
Almost always, where it is produced. Cross device analysis compares communications, activity timing and movement artifacts, and it regularly shows that the coordination described in a statement has no counterpart in the data or is contradicted by it.
We document what was lost, request the original file and recorder export, and limit our opinions accordingly. If the original is unavailable because of a retention failure, that failure itself becomes a substantive issue for counsel.
Early enough to send preservation demands to the retail or transit operator, the payment platform and the carrier. Surveillance systems commonly overwrite within days or weeks, and platform logs have retention limits that pass quietly.
