- Nationwide Digital Forensic & Cyber Investigation Services
Long term investigations produce enormous digital records: dozens of phones, years of carrier data, wiretap line sheets, surveillance logs and cloud accounts. The government's summary of all that is a theory. The data itself is testable.
Digital forensics in an organized crime case works at scale. The examination normalizes multi year, multi device productions into a single queryable timeline, attributes each device and account to a person on evidence rather than assumption, tests the alleged hierarchy against actual communication patterns, and reconciles wiretap line sheets, surveillance logs and carrier records against device artifacts. Discrepancies between those sources are where the defense evidence usually is.
A long term investigation produces more data than any narrative can hold, so the government produces a narrative instead: an affidavit, line sheet summaries, a hierarchy chart and selected exhibits. Counsel receives the summary plus a production so large that unstructured review is impossible. The practical effect is that the theory goes untested, not because it is strong, but because the data is unwieldy.
Scale also hides ordinary error. Across years of records there will be reassigned numbers, replaced handsets, shared devices, misattributed accounts, clock drift between record systems, incomplete carrier productions and line sheet summaries that compress ambiguous audio into confident paraphrase. Each of those errors is individually small and collectively decisive.
An independent review converts the production into structured data, then tests the specific propositions the indictment depends on: who used which device, who spoke to whom, when each event occurred, and whether the roles described in the chart appear in the communication record.

Illustrative only. An inventory review is the first deliverable in every large file.
| Question | Short answer |
|---|---|
| Can multi year productions be analyzed practically? | Yes, by normalizing records into structured data and querying them rather than reading them. |
| Do line sheets accurately reflect intercepted calls? | Not always. Summaries compress and interpret. Comparing them against the audio and metadata is standard defense work. |
| Can device use be attributed over years? | Often, using handset changes, subscriber records, device artifacts, account sign ins and usage patterns. |
| Does encrypted messaging leave artifacts? | Frequently. Local databases, notification history, backups and usage records survive even when content does not. |
| Can hierarchy claims be tested? | Yes. Direction, initiation, response latency and network position all speak to the roles the chart asserts. |
| Are surveillance logs reliable timelines? | They are observations with their own error. Reconciling them with device data often exposes conflicts. |
| Is a peripheral defendant separable? | Usually. Individual analysis routinely produces a profile very different from the group narrative. |
Attribution is a timeline, not a fact. The gaps belong in the record.
Converting carrier records, extraction exports, line sheets and financial data into a common schema with consistent identifiers and a single time base so they can be compared.
An investigator's summary of an intercepted communication. It is an interpretation, and the underlying audio and metadata are the evidence.
Records of which devices used which numbers over time, essential for attributing years of communication to a person rather than a line.
Local databases, keys and caches, notification history, backup copies and usage records left by secure messaging applications on the device itself.
A measurable property of a person in a communication graph, including degree, reciprocity and betweenness, useful for testing asserted roles.
| Source | Event time | Basis |
|---|---|---|
| Surveillance log | 20:15 | Observation |
| Carrier record | 20:42 | Network |
| Device artifact | 20:44 | Local clock |
| Line sheet header | 01:42 | UTC export |
Four sources, four clocks. Reconciliation is not a formality.
Illustrative only. Where the chart and the graph disagree, the graph can be reproduced.
We normalize carrier records, extraction exports, platform productions, line sheets and financial data into one queryable dataset with a single time base and verified identifiers. This is the step that makes every later analysis possible and reproducible, and it frequently reveals gaps in the production itself.
Multi year cases involve replaced handsets, ported numbers, shared devices and family accounts. We build an attribution history for each line and device using subscriber records, device artifacts, account sign ins, backup records and usage patterns, then flag every period where attribution is unsupported.
Line sheet summaries are compared against the underlying metadata and, where available, audio. Surveillance logs and pole camera records are checked against device location artifacts and carrier records. Conflicts among these sources are common and are documented precisely.
The government's chart asserts roles. The communication graph either supports them or it does not. We measure who initiates, who responds, who is reciprocal, who appears only through intermediaries, and how each defendant's position changes over time.
Where secure applications are involved, we examine what the device retains: local databases, notification history, installation and usage records, backup copies and synchronization traces. We report the limits honestly, because overstated claims about encrypted content do not survive scrutiny.
We document acquisition levels for every seized device, hash verification, chain of custody, tool versions, examiner methodology, and which devices in the file were never examined at all. Unexamined devices in a conspiracy case are a discovery issue and a cross examination theme.
Long cases require attribution to be stated year by year, not once.

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 and data analysis experts for defense counsel in federal and state organized crime prosecutions nationwide, including files with dozens of devices and years of records. Engagements generally follow four steps.

That approach turns an unmanageable production into a set of testable propositions about attribution, timing and communication patterns.
Yes. A line sheet is an investigator's contemporaneous summary. Comparing it against call metadata, the recording where available, and the surrounding communication record frequently shows compression, paraphrase or interpretation that the underlying evidence does not support.
From the device, often a great deal: installation and usage records, notification history, local database artifacts, backup copies, and evidence of when the application was active and with whom communication occurred. Content is sometimes unavailable, and we say so plainly rather than speculating.
We can measure their position in the communication graph objectively: initiation, reciprocity, direct versus indirect contact, time distribution and content availability. Where the data does not support the asserted role, the measurement shows it in a form suitable for testimony.
That is a finding worth pursuing. Unexamined devices frequently hold exculpatory context, and their absence from the report is a legitimate basis for a motion to compel further examination or production of the images.
Yes, including appointed counsel matters with approved expert funding under the Criminal Justice Act, as well as retained counsel in state and federal courts nationwide.
