Helping Attorneys Build
Stronger Defenses.
J.P. Miller is a decorated combat veteran, former Fulton County DA Major Crimes investigator, and court-qualified expert in criminal street gangs who understands how police compile files.
Defense attorneys need more than the evidence contained in a police report. Truth Hunter Investigations provides independent investigative support, careful evidence documentation, and direct collaboration with defense counsel to uncover facts that deserve a closer look.
We turn discovery materials and investigative findings into organized reports and clear visual trial aids, giving defense counsel the information needed to examine evidence, identify inconsistencies, and challenge the prosecution's case.
THE DEFENSE ADVANTAGE
TRUTH HUNTER INVESTIGATIONS
The Details That Can
Change A Case.
A strong defense starts with a thorough investigation. Truth Hunter Investigations digs deeper into the evidence, witnesses, records, and timelines to uncover overlooked details, identify investigative gaps, and give defense attorneys a clearer picture of the case.
FIND THE WITNESSES
We track down hard-to-find eyewitnesses, alibi sources, and reluctant participants using advanced skip-tracing databases and persistent field canvassing to secure clear, unvarnished statements.
REVISIT THE SCENE
A crime scene can contain details that are easy to overlook after the initial investigation. We can examine available information and conduct investigative work focused on the physical circumstances surrounding an incident.
REBUILD THE TIMELINE
A reliable timeline can help bring a complicated case into focus. We synthesize CAD dispatch logs, 911 audio, cellular data, and video records into precise chronological timelines that expose impossibilities in the prosecution's version of events.
04
REVIEW THE FOOTAGE
Security footage, surveillance video, and other recordings can provide valuable evidence. We canvass surrounding areas to locate dashcam, commercial, and residential footage before it is overwritten, analyzing every angle frame by frame to verify movements.
05
FOLLOW THE RECORDS
Publicly available records and digital information can provide useful leads. We search background databases, social media profiles, and public court filings to locate valuable impeachment material and verify the credibility of adverse witnesses.
06
FIND THE GAPS
We look at the existing investigation and identify areas that may need additional attention. That can include missing witnesses, unexplored leads, conflicting statements, incomplete documentation, or other investigative gaps.

When Our P.I.
Steps In

Every detail deserves a closer look.
01
Re-interviewing key witnesses
02
Locating missing or reluctant witnesses
03
Investigating alternative suspects
04
Challenging incomplete police investigations
05
Preparing for trial or plea negotiations
06
Developing mitigation evidence
A criminal defense attorney may know the law and understand the courtroom, but a private investigator brings a different skill set to the table.
Sometimes the most important information is outside the case file.
It may come from a witness who was never interviewed, a video that needs closer review, a timeline that doesn't line up, or someone who can provide important context about what happened.
