Picture a courtroom as a high-stakes chessboard. The prosecutor makes the first move, presenting evidence and witness testimony. But what if your defense could see several moves ahead, uncovering weaknesses in the prosecution’s strategy and finding pieces the other side didn’t even know were on the board? That’s the power of a strong partnership between attorneys and private investigators. In Tucson, where every detail can tip the scales of justice, these collaborations are often the difference between conviction and acquittal.
Criminal defense attorneys are legal strategists, but even the best strategist needs reliable information. Investigators are the detectives of the defense team, trained to dig deeper, verify facts, and uncover the truth behind the prosecution’s narrative. While police and prosecutors have their investigators, their focus is often on building a case for guilt. Defense investigators, on the other hand, are dedicated to finding the facts that support your innocence or raise reasonable doubt.
In a 2024 study by the National Association of Criminal Defense Lawyers, cases involving a defense investigator were 42% more likely to result in dismissals or reduced charges. This isn’t just a statistic—it’s a reflection of the real impact that a thorough, independent investigation can have on a case.
When the Law Office of Joel Chorny takes on a serious criminal case, the attorney and investigator become a team with a shared mission. The process begins with a detailed review of the prosecution’s evidence. The attorney identifies gaps, inconsistencies, or areas that require further exploration. The investigator then sets out to fill those gaps—re-interviewing witnesses, canvassing crime scenes, and hunting for surveillance footage that police may have missed.
For example, in a Tucson assault case, the prosecution relied heavily on a single eyewitness. The defense investigator tracked down other people who were at the scene, discovering that the original witness had a personal grudge against the defendant. By interviewing these new witnesses, the investigator gathered statements that contradicted the prosecution’s version of events. This allowed the attorney to challenge the credibility of the main witness in court, leading to a not-guilty verdict.
Investigators also play a crucial role in analyzing physical evidence. They may examine police reports for errors, review forensic lab results for inconsistencies, or consult with experts in fields like ballistics or toxicology. Their findings often become the foundation for legal motions, such as a motion to suppress evidence obtained in violation of a client’s rights.
One of the most overlooked benefits of attorney-investigator partnerships is their ability to connect with people who might be reluctant to talk to lawyers or police. Investigators are skilled at building rapport with witnesses, sometimes spending hours or even days to earn their trust. This patient, persistent approach can uncover crucial information that would otherwise remain hidden.
Consider the story of Maria, a Tucson nurse accused of prescription drug theft. The prosecution’s case was based on security footage showing Maria near the medication storage area. The defense investigator, however, noticed that the timestamp on the footage didn’t match the clinic’s official logs. After digging deeper, he discovered that the camera’s clock was set 20 minutes fast. He also obtained Maria’s phone records, which showed she was on a call with her sister at the time of the alleged theft—her cell phone pinged a tower miles away from the clinic. This evidence, combined with statements from coworkers, convinced the judge to dismiss the charges. Maria kept her license and her reputation, all thanks to the investigator’s attention to detail and the attorney’s legal strategy.
Today’s investigators don’t just rely on shoe leather and intuition. They use advanced technology to track digital footprints, analyze GPS data, and recover deleted messages or files. In Tucson, where many cases involve digital evidence from phones, computers, or social media, having an investigator who understands these tools is critical.
For instance, in a recent drug case, the defense investigator used cell tower data to prove that the defendant wasn’t near the scene of the alleged transaction. This kind of technical expertise can be the key to unlocking reasonable doubt and challenging the prosecution’s timeline.
Attorney-investigator partnerships are governed by strict ethical rules. Investigators must operate within the law, avoiding illegal surveillance or coercion. Everything they discover is protected by attorney-client privilege, meaning it cannot be shared with prosecutors unless the defense chooses to present it in court. This confidentiality encourages clients and witnesses to speak openly, knowing their information is secure.
Attorneys like Joel Chorny carefully select investigators with proven track records and require written collaboration agreements to ensure professionalism and compliance. According to a 2025 Arizona State Bar report, teams that followed these protocols reported zero ethics violations—a testament to the importance of trust and transparency.
Let’s walk through a step-by-step case study that shows how attorney-investigator teamwork can change a life.
Step 1: The Arrest
Carlos, a Tucson mechanic, is arrested for burglary after being identified by a neighbor who glimpsed the suspect running away at night. The prosecution’s case relies on this single eyewitness and a partial shoeprint found near the scene.
Step 2: The Defense Team Forms
Joel Chorny reviews the police report and immediately brings in a seasoned investigator. The investigator visits the crime scene, noting that the area is poorly lit and that the neighbor’s view was partially blocked by a fence.
Step 3: Digging Deeper
The investigator interviews other neighbors and finds a teenager who saw someone else, taller and wearing different shoes, running away that night. He also obtains security footage from a nearby business, showing Carlos at a gas station miles away at the time of the crime.
Step 4: Analyzing Evidence
The investigator compares the shoeprint to Carlos’s shoes and finds a clear mismatch. He consults with a forensic expert, who confirms the print could not have come from Carlos.
Step 5: The Courtroom
With this new evidence, Joel Chorny challenges the prosecution’s case, discredits the eyewitness, and presents the alibi. The jury finds Carlos not guilty.
This case highlights how the combined efforts of attorney and investigator—legal insight, fieldwork, and technical analysis—can expose weaknesses in the prosecution’s case and secure justice for the accused.
