What Criminal Defense Attorneys Look for When Reviewing Evidence

When reviewing evidence, a San Antonio criminal defense attorney looks for contradictions, missing information, reliability problems, and evidence that the prosecution may not be able to use in court. A police report, video, witness statement, or forensic report may look convincing on its own, but reviewing it alongside the rest of the case can reveal important questions.

If you’ve been arrested or charged with a crime, reach out to Amanda Hernandez Law, PLLC. Our criminal defense lawyer in San Antonio can compare the prosecution’s evidence, check how it was obtained, and identify problems that may support an evidence challenge or another defense strategy.

Does the Evidence Tell a Consistent Story?

Defense lawyers may compare police reports, witness statements, body-camera footage, photographs, dispatch records, and other records. They may find differences in the time of an incident, where people were located, what someone saw, or what happened afterward. A difference doesn’t automatically mean someone lied, but it can give the defense a reason to investigate further.

How Did Police Obtain the Evidence in San Antonio?

Lawyers also ask how police or investigators obtained physical and digital evidence. For example, our San Antonio criminal defense attorney may examine how officers searched your vehicle, home, or phone and whether they had the legal authority to do so. If evidence came from a search or seizure that violated the law, they may ask the court to exclude it from your case.

Can This Evidence Actually Be Used in Court?

Not everything in a police or prosecution file automatically goes before a jury. Texas Rule of Evidence 402 generally allows relevant evidence but excludes evidence that’s not relevant. Other evidence rules may also limit what the prosecution can present. For instance, a photograph may relate to the case but still face an objection under another evidence rule. A defense lawyer reviews the evidence with those rules in mind.

Could The Evidence Mislead the Jury?

Relevant evidence can sometimes create an unfair risk of confusing or misleading the jury. Texas Rule of Evidence 403 allows a court to exclude relevant evidence when its value is substantially outweighed by concerns such as confusion, unfair prejudice, or misleading the jury. A lawyer may raise this issue when a piece of evidence could distract the jury from the actual facts it must decide.

Do the Witness Statements Match the Other Evidence?

Attorneys may compare what a witness told police with what that person later says in court. The review can also show whether the witness personally saw the event or learned about it from someone else. If your case involves an eyewitness, for example, our San Antonio criminal defense lawyer may compare the witness’s description with surveillance video, photographs, and other accounts of what happened.

How Reliable Is the Scientific and Expert Evidence?

DNA, fingerprints, toxicology results, digital records, and other technical evidence may require close review. Under Texas Rule of Evidence 702, expert testimony is permitted when a qualified expert’s specialized knowledge will help the factfinder understand the evidence or determine a fact at issue. Defense attorneys may examine the expert’s qualifications, testing methods, underlying data, and conclusions.

What Evidence Is Missing?

Criminal defense attorneys may also ask what evidence is missing. That could include unavailable surveillance video, missing body camera footage, records that were never collected, or witnesses who were never interviewed. Missing evidence doesn’t automatically prove that the prosecution’s case is wrong or weak. It may, however, give the defense specific issues to investigate further.
