The Importance of Hands-On Evidence Review

In serious criminal cases, the State’s evidence can seem overwhelming on paper. Lab reports show DNA matches. Forensic analysts provide confident conclusions. Police reports document careful evidence collection. However, paper tells only part of the story.

After 25+ years of criminal defense experience, I have learned that what happens between evidence collection and laboratory analysis matters enormously. How were items packaged? Where were they stored? What other evidence shared the same container? Only by going to the evidence room and examining the physical items yourself can you answer these questions.

Unfortunately, many attorneys never conduct this critical review. Instead, they rely on discovery documents and lab reports, seeing the actual evidence for the first time at trial. By then, it is too late to challenge storage conditions, contamination issues, or chain of custody problems that could have changed everything.

What Paper Discovery Misses

Discovery documents provide essential information: police reports, witness statements, lab results, and photographs. Nevertheless, they cannot show you how officers actually handled and stored evidence. For example, a lab report might confirm a DNA match, but it will not reveal that analysts stored the DNA sample in the same container as other biological evidence from the case.

Similarly, crime scene photographs document what investigators found, but they cannot reveal what happened to that evidence over years or decades in storage. Consequently, only a personal inspection can uncover these critical details.

Paper Discovery vs. Physical Evidence Inspection

How I Conduct Evidence Reviews

When a case involves physical evidence that could determine my client’s fate, I schedule time at the law enforcement evidence room to conduct a thorough inspection. This is not a quick visit. Depending on the volume of evidence, a comprehensive review can take hours or even a full day.

Timing the Evidence View

I typically conduct evidence inspections close to trial so the details remain fresh in my mind during cross-examination and closing argument. However, I never wait until the eve of trial. If the inspection reveals problems—contamination issues, storage failures, chain of custody gaps—I need time to file motions, retain experts, and adjust trial strategy accordingly.

Who Attends the Evidence Review

I bring my investigator, a camera, and a notepad to every evidence view. In capital cases, my trial partner attends as well because two sets of eyes are essential when a client’s life is at stake. Additionally, the lead detective or evidence custodian is typically present. My team photographs every item and documents every storage container. Furthermore, we record detailed notes that can later support motions to suppress or exclude evidence.

What I Look For During Inspection

The goal is to identify anything that could undermine the reliability of the State’s evidence. First, I examine storage conditions: Did technicians keep biological evidence at proper temperatures? Second, I check packaging: Did officers place items that should remain separate in the same container? Third, I assess handling: Do the items show signs of tampering, degradation, or contamination?

Critical Areas to Examine During Evidence Inspection

Case Study: The Cold Hit DNA Case

This capital case from my files demonstrates why evidence inspection can be case-changing—and potentially life-saving. The State sought the death penalty against my client based on DNA evidence from a homicide that occurred more than twenty years earlier.

The State’s Evidence

A “cold hit” had linked my client to the decades-old crime. Investigators found a cigarette butt at the original crime scene, and when DNA from that cigarette was eventually run through the CODIS database, it came back to my client. He was already on death row for a separate homicide, making him an easy target for this cold case.

How Cold Hits Work: DNA Amplification Technology

DNA testing technology has improved immensely over the past few decades. Modern techniques can extract genetic material from even the smallest biological samples. Through a process called amplification, forensic scientists add reagents to the sample that “amplify” or increase the visibility of the DNA profile.

As a result, cold hits on cases from twenty or thirty years ago have become increasingly common. A tiny amount of biological material—such as saliva on a cigarette butt or skin cells on a doorknob—can now yield a usable DNA profile. In other words, evidence that was insufficient for testing decades ago can now generate matches through CODIS.

On paper, the case against my client looked strong. The prosecution had DNA evidence from modern amplification technology and a defendant already convicted of murder. Consequently, they felt confident.

The Evidence Room Visit

Because this was a capital case, my trial partner and I scheduled a full day at the police department evidence room. Our investigator joined us with a camera and notepad, and the lead detective was present as we methodically examined every piece of evidence.

Together, we documented how officers had stored each item over the past two decades. Our team photographed containers, recorded storage locations, and noted which items shared packaging. Although the process was tedious, it was essential. Then we found it.

The Critical Discovery

The Daubert Motion

Armed with photographs and documentation from our evidence room visit, I filed a Daubert motion challenging the admissibility of the DNA evidence. Under Daubert, scientific evidence must meet reliability standards before a court can admit it. Evidence that officers stored in a manner that creates contamination risks fails this standard.

The motion detailed exactly what we found: two pieces of biological evidence, both critical to the case, stored together for decades. Any competent forensic expert would acknowledge that this storage method created an unacceptable risk of cross-contamination.

The Result

Why Many Attorneys Skip Evidence Inspection

Conducting a thorough evidence review takes time—hours or even days that many attorneys are unwilling or unable to invest. Furthermore, scheduling access to evidence rooms requires coordination with law enforcement. The work itself is tedious: opening boxes, photographing containers, and recording observations.

As a result, too many “trial” attorneys see the physical evidence for the first time when it appears in the courtroom. By then, the opportunity to challenge storage conditions, contamination issues, or chain of custody problems has passed. Consequently, the jury sees the evidence without ever learning about problems that a thorough inspection would have revealed.

When Failing to Inspect Evidence Is Ineffective Assistance

Defense attorneys have a constitutional obligation to investigate their client’s case. When physical evidence is central to the prosecution—such as DNA, fingerprints, drugs, or weapons—failing to personally inspect that evidence can constitute ineffective assistance of counsel.

Consider the cold hit case above. If I had simply accepted the lab report at face value, my client might have received a death sentence based on contaminated evidence. The storage problem only came to light because we spent a full day in the evidence room examining every item. Consequently, an attorney who skipped this step would never have discovered it.

Therefore, if a court convicted you based on physical evidence that your attorney never personally examined, you may have grounds for post-conviction relief. An experienced appellate attorney can evaluate whether the failure to inspect evidence prejudiced your defense.

Experience in Capital Cases

I am Tampa Criminal Defense Attorney Rocky Brancato. With over 25 years of criminal defense experience, including service as Chief Operations Officer of the Hillsborough County Public Defender’s Office, I understand what thorough case preparation requires. As a death-qualified attorney, I have handled capital cases where the stakes could not be higher.

The cold hit DNA case taught me—and should teach every defendant—that lab reports are not the final word. Physical evidence has a history: collection, transportation, storage, and handling. Problems can arise at any point in that chain. Ultimately, only an attorney willing to spend hours in an evidence room will uncover them.

My client faced the death penalty based on DNA evidence that seemed airtight. Nevertheless, a full day of tedious evidence inspection revealed that improper storage had compromised the State’s key evidence. That discovery saved his life.

Who is the Best Sex Crimes Attorney in Tampa Bay

Tampa Homicide Defense Attorney

A combat veteran still serving in the Army Reserves. A cold-hit DNA match from an eight-year-old sexual battery case. And crime scene photos so graphic they would have guaranteed a conviction if this case had gone to trial without the right investigation.

The prosecution believed they had an airtight case. Years earlier, investigators had recovered a partial DNA profile from a brutal sexual assault. Then, when they ran it through CODIS—the national DNA database—it produced a “cold hit” linking to my client.

However, cold hits are only as reliable as the science and interpretation behind them. And in this case, the science was wrong. I am Tampa Criminal Defense Attorney Rocky Brancato. This post is part of our forensic series put out by the Brancato Law Firm, P.A., your Tampa criminal forensic evidence law firm.

Why I Challenged the State’s DNA Evidence

Most attorneys accept DNA evidence at face value. After all, juries treat DNA as almost infallible. But I knew that DNA analysis involves human interpretation—and humans make mistakes.

So I started by subpoenaing the bench notes from the state’s forensic laboratory. These are the raw, handwritten or typed records that DNA analysts create during testing—notes on procedures, observations, amplification levels, and more. Essentially, they reveal not just the conclusions, but the entire process.

Additionally, I obtained the electronic raw data from the lab’s DNA analysis. Then I sent everything to a confidential private laboratory for independent review. These consultants would never testify—instead, they provided a neutral second opinion and advised me on what to look for.

The Turning Point: A Critical Mismatch

My confidential lab’s review uncovered a critical issue. According to their analysis, the state’s DNA analyst may have misinterpreted one of the alleles on my client’s DNA profile at a specific genetic location.

In forensic genetics, this matters enormously. A DNA profile must match at every required location; otherwise, the person is excluded. Consequently, one mismatch can mean the difference between identification and exoneration.

Bringing in the Right Expert

To fully address the issue, I retained a university professor—an expert geneticist and DNA specialist with extensive courtroom experience. Importantly, this expert could not only understand the science but also explain it clearly to a judge or jury.

He reviewed everything: the state’s lab reports, the bench notes, the raw data, and the findings from my confidential lab. His conclusion confirmed what we suspected—there was a mismatch. Specifically, the DNA profile the state relied on did not match my client at one critical locus.

But his work did not stop there. He traveled with me and sat by my side during every deposition of the state’s forensic experts. Furthermore, he prepared me with the right questions, flagged subtle inconsistencies in their findings, and helped shape a clear and persuasive challenge to their interpretation.

When the State’s Own Experts Admitted the Truth

Then the tide began to turn. One of the state’s own experts ultimately agreed: they had it wrong. The DNA did not match at the required threshold.

Meanwhile, another state expert could not bring herself to admit her mistake. However, her testimony crumbled under scrutiny. Faced with mounting scientific evidence and internal disagreement among their own analysts, the prosecutor had no choice.

What This Case Taught Me

Had we not gone the extra mile—had we not challenged the assumptions and brought in the right expert—my client might have spent the rest of his life behind bars for a crime he did not commit.

Like many of my most significant victories, this case was won not by theatrics or charm. Instead, it was won by science, preparation, and partnership with a true expert.

Frequently Asked Questions

Can DNA evidence be wrong?

Yes, absolutely. While DNA science is powerful, the results depend entirely on proper laboratory procedures and accurate interpretation. Consequently, analyst errors, contamination, degraded samples, and misread alleles can all lead to false matches.

What is a CODIS cold hit?

A CODIS cold hit occurs when DNA from an unsolved crime matches a profile in the FBI’s national DNA database. However, these matches require the same rigorous verification as any other DNA evidence. A cold hit is only as reliable as the science behind it.

What are DNA bench notes?

Bench notes are the raw, contemporaneous records that DNA analysts create during testing. Specifically, they document procedures, observations, amplification levels, and interpretive decisions. Defense attorneys can subpoena these notes to evaluate whether the analyst followed proper protocols.

How do you challenge DNA evidence in Florida?

Challenging DNA evidence requires obtaining the laboratory’s bench notes and raw electronic data, then retaining independent experts to review the analysis. Most importantly, defense counsel must depose the state’s analysts and expose any errors or inconsistencies in their methodology.

What does it mean if DNA doesn’t match at one locus?

In forensic DNA analysis, a profile must match at every required genetic location. Therefore, if there is a mismatch at even one locus, the suspect should be excluded. One mismatch can mean the difference between conviction and exoneration.

Why do I need a DNA expert in a sexual battery case?

Sexual battery cases often rely heavily on DNA evidence. Juries treat DNA as nearly infallible, so without your own expert to challenge the state’s analysis, you have almost no chance of fighting back. As a result, the right expert can mean the difference between prison and freedom.

Facing DNA Evidence in Your Case?

DNA evidence is not infallible. Unfortunately, laboratory errors, analyst mistakes, and flawed interpretations happen more often than prosecutors want to admit. If you are facing charges based on DNA evidence, you need an attorney who knows how to challenge the science.

For over 25 years, I have defended clients against the most serious charges in Tampa Bay. As a result, I understand how to subpoena laboratory records, retain the right experts, and expose flaws in the state’s forensic analysis.
