Criminal Charges We Defend in Grayson County

The Law Offices of Richard C. McConathy handles a comprehensive range of criminal charges in Grayson County and surrounding areas. We understand that every criminal case is different, and we tailor our defense strategies to the unique circumstances of each client. Whether you’re facing misdemeanor or felony charges, our attorneys have the experience and dedication to protect your future.

DWI / DUI Defense

Texas law considers you legally intoxicated if your blood alcohol concentration (BAC) reaches 0.08% or higher. Commercial drivers face stricter limits at 0.04%, and Texas maintains zero tolerance for drivers under 21. DWI charges carry serious consequences including license suspension, steep fines, jail time, mandatory alcohol education programs, and ignition interlock requirements.

Drug Crimes

Drug charges in Texas range from simple possession to manufacturing and distribution. Penalties vary dramatically based on the type and amount of controlled substance, with some possession charges qualifying as state jail felonies or higher.

We defend clients against charges involving marijuana, cocaine, methamphetamine, prescription drugs, and other controlled substances. Our defense strategies often focus on challenging illegal searches and seizures, questioning the chain of custody for evidence, and negotiating reduced charges when appropriate.

Assault and Violent Crimes

Assault charges in Texas encompass a wide spectrum of offenses, from Class C misdemeanor assault by contact to first-degree felony aggravated assault.

Domestic violence cases receive particular scrutiny from prosecutors and often include protective orders that can affect your living situation and contact with family members. We’ve successfully defended clients by demonstrating self-defense, challenging witness credibility, and exposing inconsistencies in the prosecution’s case.

Theft and Property Crimes

Property crimes include shoplifting, burglary, robbery, auto theft, credit card abuse, and various fraud offenses. The severity of theft charges depends on the value of property involved, with thefts under $100 qualifying as Class C misdemeanors and thefts exceeding $300,000 constituting first-degree felonies. Our attorneys work to negotiate reductions, seek dismissals, or pursue alternative sentencing options like deferred adjudication when possible.

Juvenile Crimes

Young people make mistakes, but those mistakes shouldn’t define their entire future. We represent minors charged with offenses including underage drinking, drug possession, theft, assault, and other criminal violations.

The juvenile justice system operates differently from adult criminal court, with greater emphasis on rehabilitation rather than punishment. Our goal is to help young clients avoid lasting consequences that could affect college admissions, scholarships, and future employment opportunities.

Understanding the Grayson County Court System

When you’re arrested in Grayson County, your case will be processed through one of the local courts depending on the severity of your charges.

The main Grayson County Courthouse is located at 100 W Houston St, Sherman, TX 75090, while district courts (handling felony cases) are located at the Grayson County Justice Center at 200 S Crockett St, Sherman, TX 75090. Understanding what happens at each stage can help reduce anxiety and ensure you’re prepared.

What to Expect at Your Arraignment

Your first court appearance, called an arraignment, typically occurs within 48 hours of arrest if you’re in custody. During this hearing, the judge will inform you of the charges against you, ask how you plead, and set bond conditions.

Having an attorney present at your arraignment is vital because bond amounts can significantly impact your ability to continue working and preparing your defense. We regularly appear at the Grayson County courthouse and can often arrange to meet you there or arrive shortly after you’re released.

Understanding Bond in Grayson County

Bond amounts in Grayson County vary based on the severity of charges, your criminal history, and ties to the community. First-time DWI offenses often see bonds ranging from $500 to $2,000, while felony charges can result in bonds of $10,000 or higher.

The Grayson County Jail is located at 200 S Crockett St, Sherman, TX 75090 (adjacent to the courthouse). If you’re unable to post bond immediately, your attorney can file a motion for bond reduction or advocate for personal recognizance release based on your circumstances.

DWI Charges in Grayson County

Texas DWI law prohibits operating a motor vehicle in a public place while intoxicated, defined as having a BAC of 0.08% or higher or lacking the normal use of mental or physical faculties due to alcohol or drugs. Law enforcement officers in Grayson County, including Sherman Police Department, Denison Police Department, Texas Highway Patrol, and Grayson County Sheriff’s Office actively patrol for suspected impaired drivers, particularly on Highway 75, Highway 82, and FM 120, especially during holidays and weekends.

First-Time DWI Offense

A first DWI conviction in Texas is a Class B misdemeanor carrying potential penalties of up to 180 days in county jail, fines reaching $2,000, loss of driver’s license for up to one year, mandatory alcohol education classes, community service requirements, and possible ignition interlock device installation. We’ve successfully defended hundreds of first-time DWI cases, achieving dismissals, reductions, and not guilty verdicts.

Second DWI Offense

A second DWI elevates to a Class A misdemeanor with increased penalties including up to one year in jail, fines up to $4,000, license suspension for up to two years, and mandatory installation of an ignition interlock device. Prosecutors take repeat offenses seriously, but experienced defense attorneys can still challenge the evidence and fight for reduced charges.

Felony DWI

A third DWI conviction becomes a third-degree felony punishable by two to ten years in state prison and fines up to $10,000. DWI also becomes a felony if someone suffers serious bodily injury (intoxication assault) or dies (intoxication manslaughter) as a result of the intoxicated driving.

What to Do If You Are Arrested in Grayson County

Your actions immediately following an arrest can significantly impact your case outcome:

  1. Remain calm and cooperative during the arrest process while protecting your rights
  2. Exercise your right to remain silent—anything you say can be used against you
  3. Request an attorney immediately and clearly state you want legal representation
  4. Do not answer questions without your lawyer present
  5. Contact a criminal defense attorney as soon as possible after release

Early legal representation is critical because evidence disappears, witnesses’ memories fade, and prosecutors begin building their case immediately.

DWI Defense Strategies Used by Our Attorneys

Successfully defending DWI charges requires technical knowledge, trial experience, and attention to detail.

Challenging the Traffic Stop

Law enforcement officers must have reasonable suspicion of criminal activity or traffic violations to initiate a traffic stop. If the officer lacked proper justification for pulling you over, any evidence obtained during the stop may be suppressed. We scrutinize dash cam footage, officer reports, and witness statements to determine whether the stop was lawful.

Questioning Breathalyzer Accuracy

Breath testing devices require regular calibration and proper maintenance to produce accurate results. Improper administration, medical conditions, residual mouth alcohol, and machine malfunctions can all produce falsely elevated BAC readings.

Improper Field Sobriety Testing

Standardized field sobriety tests must be administered exactly as prescribed by the National Highway Traffic Safety Administration. Many officers fail to follow proper procedures, give incorrect instructions, or conduct tests under conditions that make accurate performance impossible. Physical conditions, injuries, footwear, road surface, and weather can all affect test results.

Violation of Constitutional Rights

Your constitutional rights don’t disappear when you’re suspected of DWI. Unlawful stops, illegal searches, failure to read Miranda warnings before custodial interrogation, and coercive questioning all violate your rights. When police violate constitutional protections, the evidence they obtain may be suppressed.
