Shannon Locke is a Board Certified Criminal Defense Attorney who believes deeply in putting his client’s needs at the center of his representation. In the fifteen years he has practiced criminal law Mr. Locke has tried cases ranging from Murder to Aggravated Assault, Possession with Intent to Deliver, to DWI to Domestic Violence. While based in San Antonio, TX Mr. Locke has practiced in a number of Texas counties and has tried cases in Hays, Kendall, Gillespie, and Bexar County and dismissed cases in counties such as San Patricio County, Guadalupe, Nueces, Kerr and Comal County. Mr. Locke understands that a criminal case is a crisis for his clients no matter how big or how small the accusation. As a result, he works hard to understand their needs, communicate with them after hours, and do everything possible to minimize the consequences of their criminal accusations.

Mr. Locke’s career prior to becoming a defense attorney allows him to understand how people who are accused of crime suffer under the burden of the accusation. After working at a Fortune 500 company for three years, he attended the University of Arizona Law School and graduated in 2002. He became a prosecutor at the Pima County Attorney’s Office. As an Assistant County Attorney in the Pima County Attorney’s Office, he prosecuted for the Misdemeanor Unit, the Vehicular Offenses Unit, the Property Crimes Unit and the Gang Unit. During his time with the Pima County Attorney’s Office, Mr. Locke first chaired one hundred jury trials ranging from misdemeanors to gang crime. In 2005, Mr. Locke was the only prosecutor in Pima County to successfully first-chair two first degree murder trials.

After moving to San Antonio, Texas he worked in the Bexar County District Attorney’s Office. There, he prosecuted financial crimes in the White Collar Crime Unit. He recently left the Bexar County District Attorney’s Office and is using his trial experience and complex litigation skills. Whether it’s a misdemeanor DWI or a complex Federal case Mr. Locke will work to find the best possible solution for your case.

As a criminal defense attorney Mr. Locke puts his trial experience to work for you. He looks at every case asking himself three questions 1) Were your constitutional rights violated? 2) How will the State prove this case beyond a reasonable doubt? 3) If we go to trial what are the risks the client might face? After evaluating the case he meets with his clients to inform them of his findings and how he can use the results of the investigation to achieve his client’s goals. At The Locke Law Group we consider legal representation a sacred trust. You have trusted us with your freedom and strive to honor that trust.
