          About Haskell (Trey) Tull

          Haskell (Trey) Tull is a Criminal Investigator at The Nieves Law Firm, providing our attorneys with an experienced investigator they can rely on as they work through the criminal justice process for their clients. Trey’s experience in the criminal justice system is thorough, having previously worked in law enforcement and spending nearly 10 years working in various capacities including patrol, investigations, SWAT, and as a K9 handler. He investigated numerous crimes ranging from misdemeanor drug cases to felony sex assault crimes and homicide cases. He began noticing that police officers were not following the correct protocols and procedures when investigating crimes, however, and the officers and their corresponding agencies were not being held accountable. This is what ultimately caused him to leave the law enforcement field and begin practicing as a private investigator. Trey uses his prior work experience to help defend the clients we represent by ensuring law enforcement agencies are following the correct policies and procedures when investigating crimes.

          Trey’s certifications and experience make him an invaluable asset at The Nieves Law Firm, and one that most law firms and attorneys do not have access to. He has received a number of certifications related to the crime investigations, including certifications as a Standardized Field Sobriety Testing (SFST) Instructor, a Drug Recognition Expert (DRE), a Field Training Officer (FTO), a Department of Homeland Security Active Shooter Instructor, a Close Quarters Combat Instructor, and a Chemical and Less Lethal Munitions Instructor. This provides Trey and The Nieves Law Firm’s team with firsthand insight into the tactics law enforcement officers use and how they are supposed to be utilized to safely conduct operations. He has extensive experience in the standards and training set forth by the National Highway Traffic Safety Administration (NHTSA), which is important because failure to follow these standards invalidates the results of the tests.

          Prior to joining The Nieves Law Firm, Trey worked as an independent private investigator after leaving the law enforcement field. He is a Veteran of the Marine Corps, where he was honorably discharged at the rank of Sergeant. Trey had multiple deployments, serving in Afghanistan in support of Operation Enduring Freedom and Iraq in support of Operation Iraqi Freedom.

          When Trey is not assisting our attorneys with the investigation of crimes or determining the validity of law enforcement investigation procedures, he enjoys doing a variety of physical activities. He spends his spare time working out, running, and hiking. As a native of Louisiana, Trey spends most Saturdays in the fall cheering on the LSU Tigers.
