Criminal Defense Investigations in North Carolina
A criminal case can raise questions that need more investigation than what is already in the case file. Blackwell's PI Services supports criminal defense attorneys with witness work, fact gathering, scene documentation, public-record research, field investigation, and other case-related investigative assignments.
Our role is to gather and document facts for attorney review—not to provide legal advice or determine legal strategy.
Investigative Support
How a Criminal Defense Investigator Can Help
Different cases require different types of follow-up. Depending on the investigative need, Blackwell's may assist with:
Review Case Information
Review case information and investigative leads provided by counsel to identify people, places, timelines, or facts that may need additional follow-up.

Explore Background & Public-Record InvestigationsField Investigation & Surveillance
Follow up on investigative leads in the field or conduct lawful surveillance when observation and activity documentation are relevant to the assignment.
Explore Surveillance OperationsWhen a Witness Is Part of the Case
Sometimes the first challenge is simply finding the person who may have relevant information. In other situations, the witness is already known and the next step is to document what they remember.
If a witness needs to be located, learn more about our Witness & Subject Locates service.
If the witness is available for an interview, see Witness Interviews & Recorded Statements for information about fact-focused interviews and statements when appropriate.
This keeps the next step clear without requiring you to know which investigative service you need before contacting us.
Case Documentation
Scene and Case Documentation
A location can provide useful context about what could be seen, where an event occurred, or what conditions are observable at the time of the investigation.
Depending on the assignment, Blackwell's may document relevant locations through photographs, video, observations, notes, and other appropriate methods.
For work focused on a physical location, visit Scene Investigations & Evidence Documentation. When the investigative need involves observing activity over time, Surveillance Operations may be more appropriate.

Records Research
Background and Public-Record Research
Publicly available records can sometimes help clarify names, addresses, affiliations, timelines, litigation history, or other information relevant to counsel's review.
Blackwell's researches and organizes objective, legally available information based on the needs of the assignment. We do not make legal conclusions or determine whether a person is credible.

Identify the Investigative Need

Conduct the Appropriate Investigation
The assignment may involve witness work, public-record research, field verification, scene documentation, surveillance, or other lawful investigative activity.
