Drug cases in Texas can move quickly and carry consequences that last far beyond the courtroom. You may be facing accusations related to possession, distribution, or drugs found in a vehicle, home, or on your person. In many situations, people are charged based on proximity to something, assumptions about intent, or a search that should never have happened in the first place.
My name is Paul Key. I am a criminal defense attorney serving McKinney and the surrounding North Texas area, including Collin County and Dallas County. I have been practicing law since 1996. I served as an Army JAG and worked in the Collin County District Attorney’s Office before dedicating my private practice to criminal defense. If you want a lawyer who will defend you instead of pressuring you to plead guilty, call me. I will speak with you in confidence about your case and explain what it would cost for me to defend you through trial.

Drug cases are often built early—through statements, consent to searches, or assumptions made before evidence is fully tested. The safest move is to stop talking about the case with anyone but your lawyer. Do not try to explain the situation, do not consent to searches, and keep all paperwork if you have been arrested. Possession is a legal concept, and the State must prove more than mere presence, especially when drugs are found in a car, apartment, or shared space.
Statements and searches can lock in the case early.
The State must prove control and lawful police conduct.
Early action gives you a real chance to defend the case.
Many drug arrests follow traffic stops, “probable cause” claims, consent searches, and searches tied to warrants. These steps are not automatic and they are not immune from challenge. A case can change significantly depending on whether the officer had legal grounds to stop you, extend the stop, search your vehicle, or enter your home.
My job is to examine what actually happened, not what the report claims happened. That includes looking closely at:
If the State’s evidence was obtained unlawfully, it can be challenged. That is why early defense work matters.
Drug cases require careful review of facts, timelines, and evidence handling. They also require an understanding of how prosecutors build these cases and how they try to prove possession, intent, and knowledge.
When I defend a drug charge, I typically focus on:
● Obtaining and reviewing offense reports, witness statements, and any dash/body camera video
● Evaluating the legality of the stop, detention, and search
● Identifying suppression issues when evidence was gathered improperly
● Reviewing lab testing and chain of custody issues where the substance must be proven
● Challenging assumptions about who owned or controlled the alleged drugs
● Evaluating whether the State can prove intent when the charge goes beyond simple possession
● Preparing the case as if it may need to go to trial
Some cases can be resolved without trial. Some should be tried. Either way, you should not be pressured into pleading guilty without understanding the evidence and the long-term consequences.

People often come to me for drug charges because they are trying to understand how they could be arrested when the facts are not as simple as the police report makes them sound. Common situations include:
If you are not sure whether the State can prove the drugs were yours, that is exactly what a defense attorney is supposed to test. Call and we will talk through what happened.

Drug cases often hinge on what Texas law considers possession. The State typically must prove more than “it was nearby.” They often try to prove knowledge and control, sometimes using circumstantial facts like where something was located, who owned the vehicle, or what was said during the stop.
In real life, drugs can be left in a vehicle by someone else. They can be found in shared spaces. A person can be accused simply because they were present. These cases require careful, methodical defense work to separate assumptions from proof.
If you are facing a drug charge in McKinney, Collin County, or Dallas County, do not assume the State’s version is the only version.
Drug charges can bring significant consequences, depending on the alleged substance, amount, and circumstances. A responsible lawyer does not promise outcomes without reviewing the evidence. What I can do is make sure you understand what you are facing and defend the case in a way that protects your future. Depending on the charge, consequences may include:
Jail or prison exposure
Probation or community supervision requirements
Fines, fees, and court costs
Drug testing and treatment requirements
Employment, professional, and career consequences
Driver’s license and immigration consequences
A criminal record from a drug case can create long-term barriers. That is why it matters to defend the case properly from the beginning.
Drug cases are prosecuted locally, and the way these cases are handled can depend on court practices and prosecutorial approach. I have practiced law since 1996, including service as an Army JAG and work in the Collin County District Attorney’s Office. My private practice has been dedicated to criminal defense, and most of my cases are in Collin and Dallas Counties. That local familiarity matters when you are dealing with a system that is moving quickly and expecting you to make decisions before you have full information.
If you are in McKinney, TX 75070 or nearby and you need help with a drug charge, call me.

Yes. The State may still try to prove possession using circumstantial evidence, even when ownership is disputed. A defense attorney’s job is to force the State to prove the case and to challenge assumptions.
That is common. Cases like this often turn on who had control, who had access, and what evidence exists to connect the drugs to a specific person. The facts matter, and they need to be analyzed carefully.
In most situations, no. Statements can be misunderstood or used against you later. If your side needs to be presented, it should be done through counsel.
Yes, depending on what happened. Stops, detentions, consent searches, and warrants can all be challenged when they violate constitutional requirements. That is one reason why video and timelines are so important.
Consent does not automatically end the defense. The circumstances of consent and what happened during the search still matter. The case needs to be reviewed to determine what can be challenged.
Fees depend on the charge and what it will take to defend the case properly. After I understand the facts and what you are facing, I will explain the fee and what it covers.
That depends on the charge, your history, and the evidence. The purpose of an early, structured defense is to reduce risk and protect your future as much as possible.
If you are facing drug charges in McKinney, Collin County, or Dallas County, you need a defense strategy built on evidence, constitutional protections, and preparation. You also need a lawyer who will defend you rather than pushing you into a guilty plea because it is easier for the system.
