- Nationwide Digital Forensic & Cyber Investigation Services
A single alleged transaction usually rests on an informant's phone, a short recording, a set of text messages and an officer's account. Each of those has forensic properties, and each one can be examined independently.
Sale and delivery cases turn on a narrow set of digital evidence: the messages that set up the alleged transaction, the informant's device, the audio or video recording, and the location data around the buy. Independent forensics reconstructs the complete message thread rather than the excerpt, tests whether the recording is complete and unedited, examines whether the informant's phone was preserved at all, and compares the claimed timeline against device artifacts.
In a typical controlled buy file, the digital evidence is thin and heavily mediated. The messages arranging the transaction are usually produced as screenshots from an informant's phone rather than as an extraction. The recording is often partial, starting after contact and stopping before departure. The informant's device is frequently returned or never imaged, which permanently removes the most direct record of the arrangement.
Identification is the other weak point. Where the recording is poor and the officer's observation is from a distance, the state may lean on a phone number, an account name or a contact label as identification. Each of those is a technical claim about attribution that can be tested against subscriber records and device artifacts.
An independent review pursues the complete communication record, authenticates and analyzes the recording, tests the identification chain, and documents what was never collected. In a single transaction case, what is missing often matters as much as what exists.

Illustrative only. Six of these lines convert directly into discovery requests.
| Question | Short answer |
|---|---|
| Was the informant's phone preserved? | Frequently not. Its absence is a documented discovery issue and a cross examination theme. |
| Can a recording be tested for edits? | Often. Container structure, encoding history, continuity and metadata can indicate interruption or editing. |
| Are screenshots acceptable evidence of the arrangement? | They carry no database context. Native extraction is the standard for message evidence. |
| Does a contact label identify a person? | No. Labels are user created text and prove nothing about identity. |
| Can device data test the buy timeline? | Yes. Location artifacts, app usage and network joins independently document movement and activity. |
| Is a phone number sufficient identification? | No. Subscriber records, reassignment history and device artifacts all bear on who used a line. |
| Do the officer's notes match the data? | That comparison is standard, and discrepancies of time and sequence are common. |
Every link in an identification chain is a technical claim that can be tested.
Pre buy and post buy reports, funds records, surveillance notes and recording logs. Their internal timeline can be compared against device and carrier data.
Whether an audio or video file represents an uninterrupted capture. Encoding structure, timestamps and container metadata can reveal starts, stops and re encodes.
Imaging the confidential source's phone at the time of the operation. Where it was not imaged, the primary record of the arrangement is gone.
The evidentiary path from an account, number or label to a named person. Every link is testable against subscriber and device records.
Direct collection of message databases with true timestamps, ordering and deletion state, as opposed to screenshots or printouts.
| Event | Report | Device artifact |
|---|---|---|
| Pre buy briefing | 15:40 | Not applicable |
| Arrival at location | 16:05 | 16:22 |
| Transaction | 16:10 | No device activity |
| Departure | 16:15 | 16:31 |
Illustrative only. Independent records either corroborate a narrative or they do not.
The available evidence quality, not the case size, determines what can be proven.
Where any device is available, we extract natively and rebuild the entire arrangement thread with true timestamps, direction, deletions and gaps. Excerpted screenshots regularly omit who initiated contact, how many attempts went unanswered, and the exchanges that frame the alleged agreement.
We document whether the source's phone was imaged, when, at what acquisition level, and what was produced. Where it was never preserved, that fact is stated precisely along with what evidence it would have contained, which supports both discovery motions and cross examination.
Recordings are examined for continuity, encoding history, container structure, timestamp consistency and signs of re encoding or interruption. We also assess intelligibility limits honestly, because a poor recording cannot support a confident identification.
Phone numbers, account handles and contact labels are traced through subscriber records, reassignment history, device artifacts and account data. Contact labels in particular are user created text with no evidentiary weight on their own.
Device location services, mapping history, wireless and Bluetooth connections and vehicle data are compared against the pre buy, buy and post buy times in the reports. Discrepancies in sequence or duration are documented precisely.
We review what was collected from each device, hash verification, chain of custody, tool versions and time zone handling, and we produce a list of what should exist and was not produced. In a single transaction case that list is often the most valuable deliverable.
A recording proves what it captured, and the gaps belong in the analysis.
[x] Acquisition level documented [ ] Hash values recorded and verified [ ] Chain of custody complete [~] Tool and version identified [ ] Raw acquisition produced to defense [ ] Time zone of report stated [ ] Cloud and account sources identified [~] Conclusions tied to underlying artifacts
Each unchecked line is a motion, a cross examination question, or both.
Independent examiners and court qualified expert witnesses, including former law enforcement forensic examiners. Work product protected when retained through counsel.

| Question asked | Does the data support the investigative theory | What can the data prove and what can it not prove |

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 state and federal sale, delivery and distribution matters nationwide. Engagements generally follow four steps.

We state precisely what evidence the device would have held, including the complete arrangement thread, deletion state, contact history and location artifacts, which supports a motion to compel and provides direct cross examination material.
Often. Encoding structure, container metadata, continuity of the audio stream and timestamp consistency can indicate stops, starts and re encoding. We also state clearly when a recording is inconclusive rather than overreaching.
No. Contact labels are text the device user typed. They can be a nickname, a wrong name, or intentionally inaccurate, and standing alone they establish nothing about who used a number.
Frequently. Location services, mapping history, wireless network joins and vehicle records provide an independent movement record with far more precision than the surveillance notes, and sequence conflicts are common.
We attempt to tie each screenshot to an underlying source, including native databases, notification history, backups or platform records. Where no source exists to corroborate an image, that absence is documented as part of the authentication analysis.
Yes. Single transaction files are often the best fit for independent review, because the digital evidence is narrow, concentrated and fully testable within a short engagement.
