Richard Alpert


Richard Alpert is one of the nation’s foremost experts in the prosecution of intoxication related offenses ranging from Driving While Intoxicated to Intoxication Manslaughter. He served as a prosecutor in Tarrant County for 30 years before retiring. He is the author of DWI Investigation and Prosecution and Intoxication Manslaughter Investigation and Prosecution.

He has spoken at over 400 seminars training prosecutors, judges, defense attorneys, scientists, medical personnel and law enforcement agents. Richard Alpert also served for almost two decades as the Course Director for the Texas District and County Attorney Association’s Trial Skills Course and Intoxication Manslaughter School. He also served on the Texas Forensic Science Commission.

Richard Alpert is currently working as a lecturer, instructor, and legal consultant with focus on alcohol and drug related crashes and trial advocacy training to aid in the professional development of prosecutors and law enforcement professionals in Texas and throughout the United States. He is also employed as a member of the Adjunct Faculty at Baylor Law School.  Prosecuting attorneys, law enforcement agencies, and civil attorneys representing victims of drunk drivers may contact him through this website. He is not available for consultation on defense matters. 

To be a prosecutor in Texas is to be part of a family, a family that fights for justice, a family full of brothers and sisters that are not afraid to march forward, when the odds are against them and their only weapon is the heartfelt belief that their cause, no matter how hopeless, is just. We do this not for fame, for most of the battles we fight are out of the public eye. We do this not for money, for most others in our profession are better compensated. We do this because we are called to do this. We do this because our hearts tell us we must. When one of us wins a battle, we rejoice. When one of our number falls, we grieve. And when one of our family falls, dragged down by an enemy that fires and flees, we all weep, we all pray, and we all know that the best way to honor the memory of our fallen brother is to carry on.

Texas Prosecutor's Creed
by Richard Alpert

In my 35 year career, I have never met a more passionate, bold, and more knowledgeable person on DWI as Richard Alpert. His boldness led to a new normal in DWI enforcement, not only in Texas but in many states throughout the country. His passionate approach ushered in the Gold Standards of Truth and Justice with DWI blood draw evidence. Richard is simply top shelf and one of the best prosecutors in Texas. It is an honor to call him “friend” and it has been great honor being in the battle with him.

Bill E Waybourn
Tarrant County Sheriff


Richard Alpert has tried over 155 jury trials including:

  • 37 Homicide/Death Trials
  • 2 Capital Murders
  • 14 Murders
  • 6 involved officers killed in the line of duty.

Richard Alpert gained national recognition for successfully prosecuting Chante Mallard in the Windshield Murder case. He also tried the first DWI Felony Murder in Tarrant County. Richard Alpert was the lead prosecutor in the so-called “Affluenza Teen” Ethan Couch’s criminal case, in which Ethan Couch was convicted of Intoxication Manslaughter.

Richard is probably one of the most prepared lawyers I have ever seen. I’ve prosecuted with him, defended against him and judged him in criminal cases and his preparation was always the same. He does not leave any stone unturned. Richard is credited with bringing DWI science and victim advocacy to the forefront. His knowledge of specimen analysis is only matched by scientists. He is brilliant. I can’t say enough good things about him.

Richard has always pushed those of us around him to be better at what we do — and those of us around him are all the better because of it. I have seen Richard Alpert go toe-to-toe with the toxicologist on the other side, knowing the papers and studies they were using, and also knowing the papers and studies that dispelled their stand on the matter. He is a true master, a great teacher, mentor, and friend.
