not guilty

State v. A.J.

412th Brazoria County

5/7/21

Aggravated Assault with a Deadly Weapon Client is a local criminal and civil trial lawyer. Three years ago, on 5.5.2018 he was taking his wife to get waxed before her 4D Ultrasound. Yes, they were expecting their first child. While he is waiting in the car, another lady gets into her car and bumps his door and breaks his mirror. He gets out and lets her know she hit his car. She denies it ever happens. Rather than be confrontational he takes a picture of her and her license plate and goes into the waxing salon. The lady then gets on the cell phone and calls her husband to come down there and handle it. The guy “victim” double parks his jag in the fire lane and walks right into the salon at 11:50am and calls our client out.  Mind you our client is an African American male, 5’11” 240lbs with full sleeve tats, a beard, played full back for Texas A&M and has been a concealed hand gun owner for the past 10 years. The “victim” is also an African American male about 6’3” 215 with bulges in his pockets. (I even asked the jury in opening and closing: who walks in and calls our client outside when he is a big dude, unless you have the ultimate equalizer…).  Our client has no idea who this guy is but politely declines. The man tells our client that he threatened his wife and child and to get outside. Our client starts putting 2 and 2 together (even though he never saw a child) and says it’s a civil matter.  Guy that gets shot says then why didn’t you call the police and our client says again, cause it’s a civil matter. The guy then says: it’s no longer civil, it’s physical now. The owner of the shop asks them to leave because of this commotion. Client knows that he can’t stay and be a trespasser, so as they are walking towards the door, he sees a huge gun printing through the t-shirt in the small of the man’s back.  Our client draws his Glock .40 to defend himself if necessary. As the other guy opens the door, he spins back to face my client in the doorway. As he spins, he reaches for the small of his back.  Our client has no choice but to fire his weapon. He hits the man square in the chest and once under the right arm pit as the man spins instinctively after being shot. Our client get out of the doorway and gives the gun to his wife to put in her purse and surrenders peacefully to police. During the trial and investigation we were able to show the jury what appeared to be a big gun in the small of his back. Additionally, yes the man that was shot was an engineer, but he was also a convicted felon at the State and Federal level. He and his wife knew that he would go back to prison if he really had a gun, so conveniently the gun disappeared. We were able to show how his wife was a trauma nurse but did nothing to help her shot husband, instead ran back to her car (maybe to put something in it?) and then get her purse out and never let the police near her purse. Trial was a week long and one of the most contentious trials I’ve ever experienced. I tried it with Steve Gonzalez out of Brazoria who was simply masterful. He was amazing to watch in trial. We fought the DAs, Judge, and witnesses every day. The DAs only called witnesses that they liked their version. They constantly left out the truth and would only allow evidence in that helped them. Although we stipulated to all of the evidence, the State would object to evidence they didn’t like to be sustained by the Judge. In the end, the jurors got it right and gave our client his life back. Almost 3 years to the date, he was given a second lease on life.  Thank you so much to the ladies and gentlemen of that jury for seeing the truth and realizing that he acted in self-defense for his life. It was a very difficult case since no weapon was found on the man that got shot, but the jury understood that you can use deadly force against deadly force whether it’s a real gun or not, and it’s all in the mind of the person protecting themselves. Thank you to God and that jury for getting it right. I see our client around the courthouse. They are expecting their second child and he thanks God and them too. The man that was shot survived thanks to 4 heroic nurses that were close by and able to save his life. This case goes to show the real harsh reality when a licensed gun owner is in real fear for their life and what happens when they have to act to save your own life.

If Mark can’t get you a win, nobody can

Simply put, Mark Thiessen is a criminal defense all-star. If he can’t get you a win, nobody can. I’ve worked with Mark and his team on two very different cases, and both times I’ve been blown away by the level of honesty, strategy, and respect that Thiessen Law Firm brings to the table. You can feel the difference the second you step in the courtroom with Mark by your side. The time he has taken to build relationships and earn respect is clear. He knows how to push the envelope while still being respectful of the system when it matters. Best of all, he knows where the “win” is, even when “not guilty” isn’t possible. He won’t send you to trial when he knows it won’t work, and he won’t just roll over and charge you for the same lame deal everyone gets. Mark and his team carefully look at ...

Mark Thiessen Has The “IT” Factor

Often times we hear about how Michael Jordan or Tom Brady just have/had that "IT" factor. In the sporting world the "IT" factor will win you games and championships. In the work world the "IT" factor will earn you praise, money, pretty girls/or guys if that’s your preference and MONEY..... When it comes to the LAW and the "IT" factor; it can mean your freedom or justice. We often take our freedoms for granted and find ourselves on the other side of the law. In that case we have to rely on a lawyer to defend our rights when we or someone else violates our freedoms. In my case, my freedom was violated when an intoxicated group of people decided to gang up on me at a house party in what I would consider a nice part of Houston. Never would I have thought that I would have to defend my freed...

My case is now dismissed and I can finally put this all behind me.

I am a professional business leader part of a Fortune 1,000 company. A year and a half ago my mother has just diagnosed with stage four ovarian cancer. At 8 pm on a Thursday night my stepdad called and told me that she had been rushed to the medical center. I made a terrible decision!! To get in my car to be there for my mother. I was pulled over and charged with Driving while intoxication. Never being faced with anything like this, I did not where to turn for help. I called a friend that had gone through something very similar in the past and she without hesitation told me to call Mark, she gave me his cell phone number and within 24 hours I was sitting in his office. He was very honest and sympathetic to my situation. He took my case and we went through the process. He always t...

I couldn’t have gone with a better law firm

I have to start off by saying how thankful I am that my case was dismissed. I never thought I would need a criminal lawyer but life happens. Mark kept me informed during the entire process. My case was rescheduled a few times, which was incredibly frustrating, but Mark kept calm. He had a game plan from start to finish. I couldn't have gone with a better law firm.

I recommend Mark Thiessen

Bonjour. Je tiens à apporter ici le témoignage de mon entière satisfaction concernant l’action menée par Maitre Thiessen au cour de l’instruction préalable à mon procès devant la cour criminelle du comté de Harrys. Je me suis fait arrêté par la police et contrôlé positif à l’éthylomètre au volant. Ceci est considéré comme un crime au Texas. Après avoir passé deux jours en prison j’ai été relâché sous caution et j’ai pris contact avec Maitre Thiessen sur les conseils d’un collègue de travail. Maitre Thiessen était connu de mon collègue après une conférence qu’il avait faite au sein de l’entreprise afin d’exposer et d’expliquer les lois en vigueur au Texas auprès des expatriés. (je n’étais malheureusement pas présent le jour de cette conférence !) Pendant toute l’instruction, Mai...

In one word – Fantastic

I am in my late forties and was in a bit of legal trouble for the first time in my life. It is a very stressful time for somebody who is going thru this first time. First the arrest then going through the booking process and finally spending 8-9 hours waiting to be released. Once I got out I started my research on what to do to minimize the impact. My charge was failure to ID to a police officer (a class B misdemeanor - lets just say I was in the wrong place at the wrong time and when an officer showed up i panicked and did not want to give my ID in front of people who were being questioned for possession of drugs. Anyway i got a few references of lawyers and started going and meeting the lawyers and also doing internet research on them as well as on my pending charge. Since this wa...

Thank you, Mark, for saving my career

"I’m in medical sales, so when I was wrongly accused and my career was on the line, I called the best: Mark Thiessen. Mark came highly referred to me from my friends. After reading his reviews on line and meeting him in his office, I knew I could trust Mark to fight for me. Every time he walks in the court the DAs, Judge and staff all greet him. I was honestly proud that was my lawyer when he came in. I had a very complex case with some tough issues, but Mark didn’t give up. He told me: if they want to label you a criminal and cost you your career, they can find you guilty over my dead body. We set it for trial and Mark showed up very ready. The State actually dismissed my case before trial. I was so excited but, I kind of wanted to see Mark in trial. The guy is a...

Mark Thiessen is a Jedi Master of his craft

"Mark Thiessen is a Jedi Master of his craft. Mark and his team have a keen and tactical approach to handling your case, yet still manage to maintain a lot of empathy in their communication with you. A rare combination indeed. They definitely made this process of navigating the court system as smooth as it could possible be. Things such as answering my texts late at night even on the weekends, and being there in person at the office for meetings were quite clutch. I am more than glad I went with Mark and his firm when I was a lost pup browsing the endless aisles of law firms showing up via google, ads, family recommendations, etc. Cheers to the Thiessen Law Firm."

The Best Lawyer in the Industry

I chose Mark Thiessen to represent me in a DUI / DWI case and it was the best selection/decision that I could have made. I found out about Mark through Internet search and reached out to him and his office. Upon meeting with Mark - I immediately knew that he was the right lawyer/attorney to represent me and give me the best opportunity to win my case. Mark is an expert attorney with a work ethic that is second to none. He is always available. He is a master of his craft and will give you the best opportunity to win your case. He will be prepared and he will do everything to ensure your case is won. He will actually be more knowledgable on the aspects of law, facts of the case, than the individuals that have accused you of your offense. He was highly successful in my case, even despite s...

If You Want a GREAT Lawyer, Mark Thiessen is Your Man

I found Mark Thiessen through several of my friends. I was having serious issues with the lawyer I had at the time. He kept telling me I was going to jail when I had done nothing. He did not believe me, and I believe he was gonna have me put in jail and not fight for my innocence. From the moment I met Mark Thiessen, I knew he was going to do everything for me to keep me from that horrid jail. I was not allowed to leave my county. He drove all the way up to The Woodlands to meet me at Starbucks to speak on my case. He got all the charges against me dropped within minutes. He's truly the best lawyer. He has a lot of respect from his piers including the judge that actually told me I was very lucky to have such a great lawyer. And trust me, I know I was lucky to have found him, and that is...

His knowledge of the legal system was astounding

After being arrested for a first time DWI, I felt scared, lost, and worst of all alone. I quickly started asking around and reading reviews. Time and time again the name Mark Thiessen was the main constant to every conversation or search. He, himself, called me back in less than 24-hours, set up a consultation the next day, answered all my outrageous questions patiently, and proceeded to give me an overview of how the process would play out. His knowledge of the legal system was astounding. Everyone knows DWI’s will come with a price tag as well. But I felt the price and payment plan were very reasonable, especially when your talking about your own future. You get what you pay for and WOW! I got that and even more through the process. Some people’s minds work systematically, if A happen...
