Criminal Defense Investigations

Licensed defense investigators supporting Dallas-Fort Worth defense attorneys. Witness interviews, scene work, alibi verification. 40+ years experience.

Criminal defense attorneys in Dallas-Fort Worth retain EJR Agency for one reason: thorough investigative work that holds up in court. With over 40 years of experience supporting Texas defense practices, our investigators understand what attorneys need — admissible evidence, credible witness statements, scene documentation, and findings that can withstand cross-examination.

We interview witnesses the prosecution missed or ignored. We re-examine crime scenes with fresh eyes. We verify or disprove alibis through field investigation. We locate and serve subpoenas on subjects who have gone off the grid. And we deliver case files prepared specifically for courtroom presentation — not generic investigative reports.

Defense investigations require a different mindset than civil work. Stakes are higher, timelines are tighter, and findings must be defensible under hostile cross-examination. EJR investigators have testified in Texas courts and understand both the evidentiary requirements and the strategic context of how findings will be used at trial.

Common Case Scenarios

Witness the Prosecution Missed

A defense attorney suspects there were additional witnesses to an incident that prosecutors did not interview. EJR canvasses the area, locates two witnesses with conflicting accounts of the timeline, and documents statements that become central to the defense.

Alibi Verification

A defendant claims to have been at a specific location during the time of the alleged offense. EJR verifies the alibi through surveillance footage requests, witness interviews, transaction records, and digital footprint analysis — building a documented timeline.

Prosecution Witness Background Check

A key prosecution witness has credibility issues that were not raised at the indictment stage. EJR builds a background profile showing prior false statements, motivation to testify, and inconsistencies that defense counsel uses on cross-examination.

Engage a Defense Investigator

Defense investigations are time-sensitive. Witnesses move, memories fade, scenes change. The earlier our investigators start work on your case, the stronger the evidence record at trial.

Criminal Defense: Frequently Asked Questions

How does a private investigator help a criminal defense attorney?

Defense investigators handle the field work attorneys cannot do themselves: locating and interviewing witnesses, examining scenes, verifying alibis, conducting background investigations on prosecution witnesses, locating documents, serving subpoenas, and building admissible evidence files. EJR investigators have supported Dallas-Fort Worth defense practices for over 40 years and understand exactly what attorneys need to prepare a strong defense.

Are private investigator findings admissible in a Texas criminal trial?

Yes, when collected using legal methods and properly documented. EJR investigators are trained in evidence handling, chain-of-custody documentation, and Texas evidentiary standards. Witness statements, photographic evidence, and timeline documentation produced by our investigators are routinely admitted in Texas criminal proceedings, and our investigators are prepared to testify if needed.

Can a private investigator interview prosecution witnesses?

Yes, witnesses can be interviewed by defense investigators if the witness consents. EJR investigators are trained in interview techniques that elicit accurate, detailed statements without leading or pressuring witnesses. Statements are documented contemporaneously and can be used to impeach inconsistent trial testimony.

How quickly can you start on a criminal defense case?

EJR can begin work within 24-48 hours of attorney engagement. Time-sensitive defense cases — those approaching trial dates or where evidence may degrade — receive priority. Our 24/7 operations desk handles urgent defense investigation requests across DFW.

Do you work directly with the defendant or only the attorney?

EJR works through the defense attorney to maintain attorney-client privilege coverage of investigative work product. The attorney directs the investigation, receives all reports, and decides what to share with the client. This structure protects the integrity of the investigation and the privilege protecting the work.

What types of criminal cases do you investigate?

EJR has investigated cases across the full range of Texas criminal practice — from misdemeanor defense to capital cases. Common case types include assault, drug offenses, theft, fraud, DWI, sexual assault defense, and homicide defense. Our investigators have experience with cases at every level of state and federal court.

Criminal Defense Across DFW

Criminal defense cases originating in DFW often require investigation in other Texas counties or across state lines — locating witnesses, examining scenes, verifying alibis. EJR investigators travel for cases when warranted.
