Criminal Defense Attorney San Antonio

Criminal cases in Texas are governed by the Texas Penal Code and the Texas Code of Criminal Procedure. In a large jurisdiction like Bexar County, how prosecutors build and present a case can vary significantly depending on the complexity of the investigation, the agencies involved, and the evidence collected.

The burden of proof rests entirely with the prosecution. You are not required to prove your innocence.

To secure a conviction, the State must establish every element of the alleged offense beyond a reasonable doubt.

You are also protected by constitutional rights that apply at every stage of a criminal case, including:

• The right to remain silent
• The right to legal counsel
• Protection against unlawful searches and seizures
• The presumption of innocence.

A criminal defense attorney’s role is to enforce these rights, challenge the State’s evidence, and hold the prosecution to its burden.

The strength of any criminal case comes down to the evidence—how it was obtained, how it is interpreted, and whether it can withstand legal scrutiny.

In a jurisdiction like San Antonio, cases may involve multiple officers, departments, or agencies, which can lead to inconsistencies in reports, gaps in documentation, or conflicting accounts that must be carefully analyzed.

An effective defense begins with a structured review of how the case was built. Key questions often include:

• Was there lawful probable cause for the stop, search, or arrest?
• Were constitutional rights violated during the investigation?
• Is the evidence reliable, or can it be challenged?
• Are there inconsistencies in reports, witness statements, or procedures?

Building a defense may involve multiple layers of analysis, including:

• Reviewing police reports and bodycam footage
• Analyzing surveillance, digital, and forensic evidence
• Evaluating laboratory and toxicology results
• Challenging field alcohol tests or chemical testing procedures
• Filing motions to suppress unlawfully obtained evidence
• Identifying weaknesses or gaps in the prosecution’s case.

Dr. Patino’s medical background can also play a role in cases involving personal injury allegations, intoxication testing, or disputed forensic evidence.

This includes analyzing how injuries are interpreted, evaluating toxicology results, and identifying inconsistencies between medical findings and the State’s theory.

Some criminal cases can be resolved through negotiation. Others require litigation and trial.

A strong defense strategy prepares for both from the outset.

This may involve:

• Filing pre-trial motions to challenge evidence or procedure
• Negotiating with prosecutors based on evidentiary weaknesses
• Preparing a case for jury trial when necessary.

A trial-ready approach can influence how prosecutors evaluate a case and whether they are willing to offer more favorable resolutions.

Most criminal cases in San Antonio are handled through the Bexar County criminal court system.

Lower-level offenses may begin in municipal or justice courts, while more serious charges proceed to county or district courts.

Law enforcement agencies commonly involved in criminal investigations include:

• San Antonio Police Department
• Bexar County Sheriff’s Office
• Texas Department of Public Safety.

Major highways such as I-10, I-35, Loop 410, and U.S. 281 are frequent locations for traffic stops, DWI investigations, and drug-related arrests.

San Antonio also sees a higher volume of federal criminal cases than many Texas cities, often involving multi-agency investigations, federal task forces, and proceedings in federal court.
