Beyond Trial.
Led by Private Investigator J.P. Miller, Truth Hunter Investigations provides expert appeals and habeas corpus investigations for attorneys handling post-conviction cases.
A conviction does not always mean every investigative lead was fully explored. New evidence may come to light, a witness may provide different information, or records may reveal problems that were not discovered during the original proceedings.
Our investigators work with appellate and post-conviction attorneys to examine those issues and develop investigative information that may support further legal review.
If you're handling an appeal or post-conviction case that requires a closer look at the evidence, contact Truth Hunter Investigations to discuss how we can support your investigation.

A Fresh Examination
of the Record
A conviction doesn't mean every fact has come to light. Truth Hunter Investigations takes a fresh look at criminal cases, pursuing overlooked witnesses, missing evidence, conflicting testimony, and investigative misconduct.
We locate previously unknown eyewitnesses, alibi sources, and neighborhood residents who were never interviewed during the original investigation but hold crucial details about the incident.
Our team tracks down original physical evidence, unproduced laboratory notes, and missing chain-of-custody documentation that should have been provided to the defense prior to trial.
We cross-reference trial transcripts with original 911 audio recordings, dispatch logs, and field interview cards to expose major contradictions in state witnesses’ testimony.
We examine the original detective files for signs of coercive interrogation tactics, fabricated probable cause, improperly conducted photo lineups, and systemic misconduct.
We search municipal and state archives for evidence of undisclosed deals with jailhouse informants, concealed exculpatory material, and intentional Brady violations.
Forensic science evolves rapidly. We identify older forensic findings or cell tower records that a qualified expert may need to review.

Why
Experience
Matters
Appeals and habeas cases require seasoned investigative experience because successfully overturning a conviction demands complex record reviews and exceptional patience in long-term investigations. They also require a fresh perspective and a deep understanding of appellate strategy.
J.P. Miller brings this experience as a decorated combat veteran and former Fulton County District Attorney’s Office Major Crimes Division investigator, handling homicides, racketeering, and major enterprise cases.
Having trained law enforcement nationwide, Miller knows how to identify overlooked evidence, investigative shortcuts, and procedural errors, helping post-conviction counsel develop evidence and sworn affidavits to support constitutional claims.

Ineffective assistance claims
06
Wrongful convictions
Post-conviction investigations can become important when new information raises questions about the original trial or conviction. These cases require careful investigation because relevant information may be buried in old records or connected to people who haven't been contacted in years. We investigate those issues carefully, document what we find, and provide the information to the attorney handling the post-conviction matter.

Beyond
the Verdict.
Appeals investigations examine whether the original decision was procedurally fair and sound. We focus on procedural errors, investigator bias, and newly discovered evidence that may support overturning or reconsidering a conviction.
How Can Our Private Investigation Team Help After a Conviction?
01
We comb through thousands of pages of original trial and motion hearing transcripts, police bench notes, and exhibit lists. This meticulous review highlights critical inconsistencies, unpursued leads, and procedural errors that may have occurred during the initial trial proceedings.
02
Perspectives, loyalties, and circumstances change over time. We locate original trial witnesses and conduct professional, unpressured interviews to discover if their original statements were influenced by police coercion, fear, or unfulfilled prosecutorial promises.
03
Evidence once considered insignificant can become critical to a habeas petition. We search for physical items, surveillance video footage, or dispatch records that trial counsel never requested or that the state failed to disclose.
04
We follow up on alternative suspect leads, alibi details, and neighborhood tips mentioned in initial police logs but never investigated by law enforcement or previous defense teams.
05
Appellate and habeas litigation follows strict procedural rules and filing deadlines. We work closely with appellate counsel to align affidavits, timelines, and field reports with their post-conviction legal strategies.
Before You Reach Out.
Get clear information about our work, the process, and what to share through our helpful FAQ.
Yes. When an attorney identifies specific issues that may support a wrongful conviction claim, an independent investigator can help investigate those issues and develop additional factual information.
A Brady violation occurs when the prosecution fails to disclose material, exculpatory evidence to the defense. An investigator uncovers these violations by:
• Searching public archives
• Interviewing witnesses
• Locating undisclosed police files that prove favorable evidence was withheld
Yes. We use advanced skip-tracing databases, public records searches, and persistent field canvassing to track down witnesses who moved away or lost contact since the original trial took place.
We document witness recantations carefully so defense counsel can evaluate them for use in court. We conduct recorded, voluntary interviews, explore why the witness originally gave false testimony, and secure detailed, sworn affidavits that clearly explain the truth without coercive pressure.
Yes. Our firm assists appellate counsel on state habeas proceedings throughout Georgia, federal post-conviction motions across federal district courts, and provides nationwide post-conviction consulting.
